The brightly colored Red Efts are usually found on the forest floor on moist days particularly during and after heavy showers on days when the temperature is above 50 degrees. After a period of rapid growth, the resultant larvae undergo metamorphosis and begin to migrate from the breeding ponds in the late summer and fall during rainy periods (Healy, 1975). Ours is the Red-spotted Newt. 47-48. They remain active and above ground as long as the surface leaves are wet and disappear as the leaf litter dries. Larvae live in water and use gills to breathe. Lizards typically have dry skin; most salamanders stay moist, and many of them use their wet skin as a surface through which to breathe. James H. Harding and David A Mifsud. This pattern is seen among populations where the breeding pools are shallow or seasonal, with adults migrating out of ponds in summer or fall, overwintering on land, and returning to their pond the following spring to breed.
