Often sold as a pet, this eastern tiger salamander is endemic to North America and grows as long as 37 cm in length. Along with baby mice and small frog, they also consume small worms and insects.

An important thing about these wild amphibians is that the larvae are unable to undergo metamorphosis and the adults remain gilled and aquatic throughout their life.

The water monster has now become critically endangered as declared by the IUCN.

Owing to its great degree of terrestrial adaptation, long range movements, surprising habitat associations and, especially, freeze tolerance, it has been a piece of great attraction for the biologists throughout the 20th century.
