Erycis

The Erycis are a hydra species from Auriga from the Endless Legend franchise.

Physiology
They are large and formidable multi-headed hydra. While they appear to be monstrous beast they have hands with claws capable of manipulating tools, but tend to mostly prefer using their large, fearsome jaws and teeth.

They appear to be a race of bottom-feeders, capable of eating almost anything. The Erycis can extract poisons from their food and isolate them in a specialized gland allowing them to feed in extreme environments. When threatened, they can also expel the contents of that gland as a highly toxic cloud.
