4 species in 1 genus, found in NW USA
[caecilian]Up to 50 cm, free swimming larva, female attends 25-40 eggs(thus oviparous)
No nasolabial or distinct costal grooves.Terrestrial as young, have laterally compressed tails as aquatic adults.
Newts
[caecilian]2 genera & 42 species, Central & South America
