The Velachif is a giant and hideous snake found above the lake of Tenochtitlan. It is amphibious like a crocodile, and extremely venomous; death is virtually certain if bitten by one. A velachif has a rounded head, a parrot-like beak, and a colorful, predominantly red body.
The inhabitants of Mexico frequently hunt it. Its flesh is of excellent quality.
