The Cope’s Giant Salamander is a large salamander found in the Pacific Northwest of the United States. Though, it is the smallest of the salamanders in its family. It is usually aquatic as they often never go through metamorphosis, keeping their gills through their life. This is called neoteny. They prefer cold, fast flowing streams in coniferous forests.
Mating and courtship of the salamander has never been seen but its believed to be similar to the other Giant Pacific Salamanders. The eggs are laid mostly in fall and spring under logs or rocks. Females do protect their nest of eggs from predators and can be very aggressive. Nest sizes can be between 25 – 115 eggs. The eggs can take up to 200 days to hatch!
