greenland shark size

All sleeper sharks – out of which the Greenland shark is but one species – are known for their slow swimming and low activity levels. How big does the Greenland shark get? Norway persecuted Greenland sharks during the 1970s, because they were considered to be a nuisance that threatened other fisheries. Coloration can range from pale creamy-gray to blackish-brown and the body is typically uniform in color, though whitish spots or faint dark streaks are occasionally seen on the back.[9]. Greenland Sharks can also live for a very long time, some scientists have estimated that the larger sharks are over 200 years old based on how much they grow in size per year. The species has been observed at a depth of 2,200 metres (7,200 ft) by a submersible investigating the wreck of the SS Central America that lies about 160 miles (260 km) east of Cape Hatteras, North Carolina. [31] In 2016, a study based on 28 specimens that ranged from 81 to 502 cm (2.7–16.5 ft) in length used radiocarbon dating of crystals within the lenses of their eyes to determine their approximate ages. [26][28] The shark occupies what tends to be a very deep environment seeking its preferable cold water (−0.6 to 12 °C or 30.9 to 53.6 °F) habitat.[1]. The shark can grow up to 21 ft (6.4 m). They grow at incredibly slow rates of around one centimetre per year and reach a maximum size of five metres (16ft). Greenland sharks come 3rd in size after whale sharks and great white. The typical lifespan of the Greenland Shark is a lengthy 300-500 years. The Greenland shark is the slowest swimmer for its size and yet it manages to hunt faster swimming seals, probably by surprising them while sleeping. https://www.britannica.com/animal/Greenland-shark, Gulf of Maine Research Institute - Greenland shark, Canadian Shark Research Laboratory - Greenland Shark, Florida Museum of Natural History - Greenland shark, Greenland shark - Student Encyclopedia (Ages 11 and up), International Union for Conservation of Nature. Greenland sharks grow to 6.4 m (21 ft) and 1,000 kg (2,200 lb),[7][8] and possibly up to 7.3 m (24 ft) and more than 1,400 kg (3,100 lb). Image credit: Julius Nielsen According to the results of the analysis – which has a probability rate of about 95 percent – the sharks were at least 272 years old, and could be as much as 512 years old (!) Despite its large size it has many small features, such as a small head, short snout and small eyes. The dorsal fins lack the rigid frontal spine found in some other sharks. [16], Although such a large shark could easily consume a human swimmer, the frigid waters it typically inhabits make the likelihood of attacks on humans very low, and no cases of predation on people have been verified. [44] It is considered a delicacy in Iceland. Greenland sharks are cold-water species that can grow to impressive lengths. It is hypothesized that they may ambush them while they sleep. The Greenland shark’s metabolism is as slow as its lifestyle. Greenland sharks are really, really big. Greenland shark Somniosus microcephalus is a potentially important yet poorly studied cold‐water species inhabiting the North Atlantic and Arctic Oceans. The bladelike lower teeth have a single cusp, or point, that slants strongly to the side; the smaller upper teeth, shaped like a lance head, also have a single cusp. The longest they grow is up to 4 meters. [11], The Greenland shark is an apex predator and mostly eats fish, and has been observed actively hunting seals in Canada. Greenland Sharks are the only true sub-Arctic shark and they live … [20] Daily vertical migration between shallower and deeper waters has also been recorded. One day we may understand this elusive and enigmatic creature better. [36] It has been estimated that due to their extreme longevity, Greenland sharks can have 200 to 700 pups during their lifetime. Please select which sections you would like to print: Corrections? Yet, it’s one of the largest sharks in the world, rivalling the great white in size. Still image from the Greenland shark footage. [32][35] Within a Greenland Shark’s uterus, villi serve a key function in supplying oxygen to embryos. It is speculated that due to embryonic metabolism dealing with reproduction, this only allows for a limited litter size of around 10 pups. [20] Daily vertical migration between shallower and deeper waters has also been recorded. This shark reaches a maximum length of about 640 cm (21 feet), although it may grow up to 730 cm (24 feet). This specific shark, one of 28 Greenland sharks to be study by the researchers, was estimated at 18 feet length and weighed over a ton, which means it could be somewhere in the range of 272 and 512 years of age. Though both large and predatory, this species is not known to be particularly aggressive and is thought to be fairly sluggish in the cold waters of the north Atlantic Ocean. Despite our dataset representing the largest sample size of Greenland sharks genetically surveyed to date, the elevated number of rare mtDNA haplotypes and the few individuals representing them, along with our failure to recover two previously reported Greenland shark haplotypes (Murray et al., 2008), suggests we have yet to capture the full extant genetic diversity of Greenland sharks. — um jammer trans g (@joffeorama) August 30, 2017 Reaction from Verge staff to the Greenland shark Twitter thread. The hemoglobins also have a lower affinity for O2 compared to temperate sharks. The Greenland shark (Somniosus microcephalus), also known as the gurry shark, grey shark, or by the Kalaallisut name eqalussuaq, is a large shark of the family Somniosidae ("sleeper sharks"), closely related to the Pacific and southern sleeper sharks. He serves currently as the editor of Earth and life sciences, covering climatology, geology, zoology, and other topics that relate to... An injured ring seal escaping from a polar bear as a Greenland shark awaits. The sharks have frequently been observed gathering around fishing boats. Lifespan:120-392 years (ma… Though currently unknown, if we were to guess we would say that sharks probably have a lifespan similar to our own – around 70 to 100 years. They are the slowest swimming fish species for their size with a normal cruising speed of about 30cm or a foot a second, 1.2 kmh (3/4 of a mph) rising to a fastest cruising speed of just over twice this, just about anything they might want to eat swims faster than them. The bulky size and small fins of the Greenland shark mean that it is one of the slowest moving fish in the oceans, with scientists calculating that its top speed is around 1.6 miles per hour – about half the speed the average adult walks. [51], 10.2305/IUCN.UK.2006.RLTS.T60213A12321694.en, "Distribution and feeding ecology of the Greenland shark (Somniosus microcephalus) in Greenland waters", "Marine fish may be biochemically constrained from inhabiting the deepest ocean depths", "Sizing ocean giants: patterns of intraspecific size variation in marine megafauna", "A review of Greenland shark (Somniosus microcephalus) studies in the Kongsfjorden area, Svalbard Norway", "Greenland Shark (Somniosus microcephalus) Stomach Contents and Stable Isotope Values Reveal an Ontogenetic Dietary Shift", "Moose-eating shark rescued in Newfoundland harbour", "Clash of the fiercest predators as shark eats polar bear", "Comment on the ecophysiology of the Greenland shark, Somniosus microcephalus", "The slowest fish: Swim speed and tail-beat frequency of Greenland sharks", "Slow Sharks Sneak Up on Sleeping Seals (and Eat Them)? [50], As both scavengers and active predators, Greenland sharks have established themselves as apex predators in Arctic ecosystems. [12] Recorded fish prey have included smaller sharks, skates, eels, herring, capelin, Arctic char, cod, rosefish, sculpins, lumpfish, wolffish, and flounder. If the meat is eaten without pretreatment, the ingested TMAO is metabolized into trimethylamine, which can produce effects similar to extreme drunkenness. The species was valued for its liver oil; about 114 litres (30 gallons) of liver oil can be obtained from a large specimen (see also fish oil). [12][13], Greenland sharks are recognized as the longest-lived vertebrates on earth. The Greenland Sleeper Shark — Somniosus microcephalus — is a rather large, and strange, species of shark native to the icy waters of the North Atlantic, and is especially common in the region around Iceland and Greenland. [21], In August 2013, researchers from Florida State University caught a Greenland shark in the Gulf of Mexico at a depth of 1,749 m (5,738 ft), where the water temperature was 4.1 °C (39.4 °F). Updates? Therefore, potential size-related feeding patterns remain poorly documented. ... filter-feeding shark is the largest known fish species alive. The species has also been dubbed: the sleeper shark, ground shark, grey shark, gurry shark, and the Inuit name for it is Eqalussuaq. When feeding on large carcasses, the shark employs a rolling motion of its jaw. In the early 1900s as many as 30,000 Greenland sharks were caught a year. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. On average, adult Greenland sharks are 6.4 m (21 ft) long and weigh 1000 kg (2200 lb), but some specimens reach 7.3 m (24 ft) and 1400 kg (3100 lb). The oldest of the animals sampled, which also was the largest, had lived for 392 ± 120 years and was consequently born between 1504 and 1744.n1 The authors further concluded that the species reaches sexual maturity at about 150 years of age. Greenland shark denticles. [3] As an adaptation to living at depth,[4] it has a high concentration of trimethylamine N-oxide in its tissues, which causes the meat to be toxic. [17], Like other elasmobranchii, Greenland sharks have high concentrations of the nitrogenous waste products urea and trimethylamine N-oxide (TMAO) in their tissues, which increases their buoyancy[37] and function as osmoprotectants. [17] It swims at 1.22 km/h (0.76 mph), with its fastest cruising speed only reaching 2.6 km/h (1.6 mph). See how you compare to some of these vulnerable predators that are so crucial to the ocean's health. The Greenland shark is one of the largest sharks in the world and is the largest arctic fish. Greenland Shark Overview — The largest member of the dogfish family, the Greenland shark can grow to over 20 feet in length. Illustration courtesy Fishes of the Western North Atlantic (1948) Size, Age, and Growth. And even more extraordinary, it’s … Greenland sharks are absurdly slow and mostly blind, yet they may have spread far beyond the Arctic waters they are known from. Greenland Sharks have extremely rough skin. Greenland sharks have the longest known lifespan of all vertebrate species (estimated to be between 300–500 years), and the species is among the largest extant species of shark. Most Greenland sharks observed have been around 2.44–4.8 m (8.0–15.7 ft) long and weigh up to 400 kg (880 lb). These three types show very similar oxygenation and carbonylation properties, which are unaffected by urea, an important compound in marine elasmobranch physiology. While they fail to rival the filter feeding whale shark and basking shark, both of which can measure over 40 ft. long, these sharks are some of the largest carnivorous species. In size it approaches that of the white shark, but its head and teeth are smaller. Greenland Sharks Love Cold Water. The shark can grow up to 21 ft (6.4 m). During the winter, the sharks congregate in the shallows (up to 80° north) for warmth but migrate separately in summer to the deeps or even farther south. in other words: this shark's body is full of pee. "The Greenland shark's eye lens is composed of a specialised material - and it contains proteins that are metabolically inert," explained Mr Neilson. Using their cryptic coloration, they can approach prey undetected before closing the remaining distance by opening their large buccal cavity in order to create a suction that draws in the prey. Let us know if you have suggestions to improve this article (requires login). The Greenland shark is one of the largest cartilaginous fishes. They are thought to prefer colder, deeper environments but may be found anywhere between the sea surface and depths of 2,200 meters (about 7,200 feet). It is bigger than the better known white shark. For this reason Greenland sharks are thought to mostly scavenge food from the seabed, using their strong sense of smell to locate food sources. It can grow to 1,200 kilos [1.3 tons], and 8 meters long [26.2 feet], the size of a great white shark. [27] These parasites also damage the eyeball in a number of ways, leading to almost complete blindness. These usually sluggish sharks have very unique physical characteristics including their varying … In spite of their small heads, Greenland sharks are large, robust sharks that reach up to 6.5 m in length and weigh up to 900 kg. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. There are no known predators of adult Greenland sharks because of their very large size. These sharks can grow up to 23 ft. long, a few feet longer than the largest great white shark. The green laser is from a photogrammetry device used to measure body size (Brynn Devine/YouTube) By Mark 'Crowley' Russell. The cloth blew into the ocean to become Skalugsuak. It inhabits the cold northern seas, and is rarely seen elsewhere. from the from the from the Bathypelagic Waters of the Northern Gulf of Mexico", "Gross morphology and histology of the olfactory organ of the Greenland shark Somniosus microcephalus", "Eye lens radiocarbon reveals centuries of longevity in the Greenland shark (, The Strange and Gruesome Story of the Greenland Shark, the Longest-Living Vertebrate on Earth, "The Conservation of the Greenland Shark (Somniosus microcephalus): Setting Scientific, Law, and Policy Coordinates for Avoiding a Species at Risk", "Counteraction of urea-induced protein denaturation by trimethylamine N-oxide: a chemical chaperone at atomic resolution", "Organic osmolytes as compatible, metabolic and counteracting cytoprotectants in high osmolarity and other stresses", "The Greenland Shark Somniosus Microcephalus—Hemoglobins and Ligand-Binding Properties", "The Greenland Shark Is A Very Odd Species Of Shark – Shark Sider", "Iceland's Wild Culinary Traditions: Hákarl and Brennivín", "My Encounter With Hákarl, The Worst Tasting Food On Earth", "Greenland Shark and Elasmobranch Education and Research Group", "Advancing Research for the Management of Long-Lived Species: A Case Study on the Greenland Shark", Greenland Shark and Elasmobranch Education and Research Group, Canadian Museum of Nature SV Greenland Shark, https://en.wikipedia.org/w/index.php?title=Greenland_shark&oldid=991224687, Wikipedia articles needing page number citations from June 2012, Articles with self-published sources from August 2016, Articles with dead external links from January 2018, Articles with permanently dead external links, Creative Commons Attribution-ShareAlike License. While not much is known about the mysterious species, it's believed they can live for upwards of 272 years. It reaches an enormous size and despite its lethargic appearance, it is a predator capable of short bursts of speed, and under certain conditions may hunt seals and even larger mammals including the beluga whale. Despite its size, the sluggish Greenland shark is easily captured; individuals as long as 16 feet (4.9 meters) have been tempted to the surface with bait and hauled out of the water with little resistance. [2] The distribution of this species is mostly restricted to the waters of the North Atlantic Ocean and Arctic Ocean. This does not seem to reduce the life expectancy or predatory ability of Greenland sharks due to their strong reliance on olfactory and acoustic sensory organs. Occasionally, sled dogs that eat the flesh are unable to stand up because of this effect. [4][39] Its presence in the tissues of both elasmobranch and teleost fish has been found to increase with depth. No other vertebrate known has a life span as long as this species; radiocarbon dating of isotopes in the shark’s eye-lens nuclei suggests that the oldest Greenland sharks may be more than 500 years old. It rivals the Pacific sleeper shark (possibly up to 7 m or 23 ft long) as the largest species in the family Somniosidae. Weight:400 kg (882 lb) on average, maximum known weight 1,000 kg (2,205 lb), maximum possible weight 1,400 kg (3,086 lb) 3. [9] It also scavenges on seals. The Greenland shark is a thickset species, with a short, rounded snout, small eyes, and very small dorsal and pectoral fins. [9] Teeth in the two halves of the lower jaw are strongly pitched in opposite directions. See more ideas about Greenland shark, Shark, Greenland. Get exclusive access to content from our 1768 First Edition with your subscription. Males are typically smaller than females. Rumors that scientists had discovered a Greenland shark aged half a millennia were first sparked in 2016 after a study that was published in the journal Science analyzed the age of the creatures, which can grow up to 21 feet long and weigh up to 2,200 pounds.. The maximum recorded size of this shark is 6.4 m, which was caught near the Isle of May in Scotland in January 1895 and weighed 1020 kg. The Greenland shark is the slowest swimmer for its size and yet it manages to hunt faster swimming seals, probably by surprising them while sleeping. A Greenland shark that was captured and tagged off Greenland in 1936 was recaptured 16 years later. [41], The flesh of the Greenland shark is toxic because of the presence of high concentrations of trimethylamine oxide (TMAO). It is, therefore, extremely difficult to kill, and unsafe to trust the hand within its mouth, even when the head is cut off. [49], The Greenland shark plays a role in cosmologies of the Inuit from the Canadian Eastern Arctic and Greenland. Size of a Greenland shark. (2006). Greenland sharks grow to 6.4 m (21 ft) and 1,000 kg (2,200 lb), and possibly up to 7.3 m (24 ft) and more than 1,400 kg (3,100 lb). Their dorsal and pectoral fins are also quite small, as are their gill slits in relation to their body size. Body length:2.44-4.8 m (8 ft – 15ft 9 in) on average, maximum known length 6.4 m (20ft 12in), maximum possible length 7.3 m (23ft 11in) 2. They're similar in size to great whites, and are part of the "sleeper shark" family due to their slow-moving nature. The Greenland shark is one of the world’s largest marine species, reaching lengths over six metres. Greenland sharks grow to 6.4 m (21 ft) and 1,000 kg (2,200 lb),[7][8] and possibly up to 7.3 m (24 ft) and more than 1,400 kg (3,100 lb). The Greenland shark {Lacmargus borealis) is the notable exception to the order. They rival great white sharks in terms of size. Similar toxic effects occur with the related Pacific sleeper shark, but not in most other shark species. The species is considered near threatened by the IUCN. The Greenland Shark can grow up to be 7 meters long (24 ft) and weigh up to 1 tonne (2,000 pounds). The 48-52 lower teeth are interlocking and are broad and square, containing short, smooth cusps that point outward. TMAO also counteracts the protein-destabilizing tendencies of urea[38][39] and of deep-water pressure. The young are born at a size of 38 cm (15 in). marine animal CC BY-SA 4.0. How old can the Greenland shark get? [24][25], The shark is often colonized by the copepod Ommatokoita elongata, which attaches itself to the shark's eyes. Greenland sharks grow to 6.4 m (21 ft) and 1,000 kg (2,200 lb) and possibly up to … Scientists have captured some very rare footage of Greenland sharks during a research project into population distribution in … Appearance To give you an idea of just how large they are, Greenland sharks usually grow up to 21 feet (6.5 meters), and they weigh approximately 2,000 lbs (900 kilos)! Greenland sharks, which only grow 1cm a … Due to their huge size, the sharks swim very slowly and have a sluggish metabolism rate, earning them the nickname of sleeper shark. [13], Greenland sharks, because of their slow speeds, often hunt prey that is asleep. No recorded Great White Shark has reached the length of the Greenland Shark. This shark prefers cold-water temperatures and will usually only ascend from the depths if the surface drops to around 33 degrees Fahrenheit. It is usually spotted near the surface during the winter and retreats to depths of 591-1,804 feet (180 to 550 m) during the summer. And even more extraordinary, it’s believed to grow over 200 years old. They display identical electronic absorption and resonance Raman spectra, indicating that their heme-pocket structures are identical or highly similar. [5] Greenland shark flesh, treated to reduce toxin levels, is eaten in Iceland as a delicacy known as kæstur hákarl. [9][15] The Greenland shark is known to be a scavenger, and is attracted by the smell of rotting meat in the water. Bulky, with a rounded snout, small fins relative to body size, and gray to brown coloration, Greenland sharks are similar to spiny dogfish (Squalus acanthias), except that they lack a spine in front of the second dorsal fin and usually the one on the first dorsal fin. Navigate parenthood with the help of the Raising Curious Learners podcast. pee shark. [47] The legend says that an old woman washed her hair in urine and dried it with a cloth. The medium gray to nearly black Greenland shark has two dorsal, or top, fins of equal size but no anal fin. The fish are gray to brown in color, sometimes with dark streaks or white spots. The type, amount, and duration of parental care the young receive are unknown, but scientists speculate that, like other shark species, Greenland sharks are independent from birth. 1. The flesh of the Greenland Shark is also poisonous and eating them can cause intestinal distress and neurological effects very similar to extreme drunkenness. It’s been around for hundreds of millions of years as a species. [18] Because this top speed is only half that of a typical seal in their diet, biologists are uncertain how the sharks are able to prey on the faster seals. The Greenland shark is ovoviviparous – producing young by means of eggs which are hatched within the body of the female. And, if we are to believe Crantz, this motion is to be observed three days after, if the part is trod on or struck. However, most sharks are 3-5 meters in length. The shark ranges in depths of 0-3,937 feet (0 to 1,200 m) and temperatures of 34-68°F (1 to 12°C). (Although the flesh of the Greenland shark may be eaten, it is toxic unless properly cleaned and dried or repeatedly boiled prior to consumption.) They are carnivorous, and their diet is often made up of several different types of fishes, including smaller sharks, eels, flounders, and sculpins. This is the likely explanation as to why the gut contents discovered in Greenland sharks is often whole prey specimens. When hoisted upon deck, it beats so violently with its tail, that it is dangerous to be near it, and the seamen generally dispatch it, without much loss of time. Recent research found that Greenland sharks can live upwards of 300 years. The distribution of this species is mostly restricted to the waters of the North Atlantic Ocean and Arctic Ocean. A Greenland shark, alive today, could have been swimming in the deep in the 1600s. The Greenland shark is brown, gray and black in colour and may have dark lines or white spots along its flanks or on the dorsal side. The weight of a big individual can be 3100 lb (1400 kg). ", Deep-C Scientists Capture First Greenland Shark in the Gulf of Mexico, "The Second Report of a Sleeper Shark Sleeper Shark Sleeper Shark (Somniosus (Somniosus) sp.) Its dorsal and pectoral fins are also quite small, as are the shark's five gill slits in relation to its body. In 1988, an unmanned submarine spotted a 20 feet (6 m) long male Greenland shark at a dep… The Greenland shark is one of the largest sharks in the world and is the largest arctic fish. Our editors will review what you’ve submitted and determine whether to revise the article. They are ovoviviparous (that is, eggs are retained within the body until they hatch) and produce an average of 10 offspring at a time. Therefore, Greenland sharks' longevity and conservative life history traits, in tandem with their vulnerability to accidental catching and commercial fishing, promotes a growing concern for the sustainability of this species. The species is primarily found in the cold-water environments of the Arctic Ocean and North Atlantic, from Baffin Bay eastward to the Barents Sea, but its range also extends southward to the North Sea and the waters adjacent to the Eastern Seaboard of the United States. Greenland shark, (Somniosus microcephalus), member of the sleeper shark family Somniosidae (order Squaliformes, which also includes the dogfish family, Squalidae) that is the longest-living vertebrate known. They have a slow growth rate, late maturity period, and low fecundity, making the management and conservation of this species very important. But for now, it disappears back into the darkness, as quietly and slowly as it appeared. But most … These characteristics are interpreted as adaptations to living at great water depths. Little is known, however, about how the species reproduces. Greenland Sharks have a total length between 12’-24’ (3.7-7.3 m) and an overall weight in the range of 1950-2250 lb (885-1020 kg). The Greenland shark actually belongs to a group of sharks called the "sleeper sharks", which all have similar characteristics. [42][43], The meat can be treated for safe consumption by boiling in several changes of water, drying, or fermenting for several months to produce kæstur hákarl. Crustaceans, seabirds, and carrion—as well as terrestrial mammals (such as horses and reindeer) that likely fell through the ice—have been found in stomach analyses of the species. One specimen was observed off the coast of Cape Hatteras, North Carolina at 2200 m (7200 ft), while another was documented at 1749 m (5738 ft) in the Gulf of Mexico. [20] Daily vertical migration between shallower and deeper waters has also been recorded. Broad‐scale changes in the Arctic ecosystem as a consequence of climate change have led to increased attention on trophic dynamics and the role of potential apex predators such as S. microcephalus in the structure of Arctic marine food … Yet, it’s one of the largest sharks in the world, rivalling the great white in size. pee shark. Greenland sharks are large fish, comparable in size to great whites and in appearance to sleeper sharks. As a result of their low productivity and extreme longevity, this species is particularly susceptible to overfishing. In the north, the shark migrates near shore in search of warmer waters. Greenland sharks are slow-moving, typically swimming at rates of less than 3 km (about 1.9 miles) per hour. [4][40], The blood of Greenland sharks contains three major types of hemoglobin, made up of two copies of α globin combined with two copies of three very similar β subunits. is questionable when Greenland sharks are released with trailing fishing gear. Traditionally, this is done by burying the meat in boreal ground for 6–8 weeks, which presses the TMAO out of the meat and also results in partial fermentation. The young are born at a size of 38 cm (15 in). Despite its large size it has many small features, such as a small head, short snout and small eyes. The weight of a big individual can be 3100 lb (1400 kg). The Greenland shark actually belongs to a group of sharks called the "sleeper sharks", which all have similar characteristics. [23] A more typical depth range is 0–1,500 m (0–4,900 ft), with the species often occurring in relatively shallow waters in the far north and deeper in the southern part of its distribution. But, they're slow-moving, plagued by parasites and on rare occasions, have been known to … Froese, Rainer and Pauly, Daniel, eds. Considering that the Greenland shark is one of the largest shark species around, growing up to 6.4m, the ‘small head’ possibly refers to a small brain, relative to body size. [9][10] Most Greenland sharks observed have been around 2.44–4.8 m (8.0–15.7 ft) long and weigh up to 400 kg (880 lb).[9][10]. [30] One Greenland shark was tagged off the coast of Greenland in 1936 and recaptured in 1952. [9], As an ectotherm living in a just-above-freezing environment, the Greenland shark has the lowest swim speed and tail-beat frequency for its size across all fish species, which most likely correlates with its very slow metabolism and extreme longevity. The species name, microcephalus, is directly translatable to "small head". Greenland sharks grow to 6.4 m (21 ft) and 1,000 kg (2,200 lb) and possibly up to 7.3 m (24 ft) and more than 1,400 kg (3,100 lb). Wow.
