The Deep Ones are an ocean-dwelling race, as evidenced by their name, with an affinity for mating with humans.

They entered a contract with the people of Innsmouth to keep the fish plentiful in their area. They also seem to have a supply of gold artifacts of unearthly design. The Deep Ones worship Father Dagon and his consort Mother Hydra.

The Deep Ones are humanoid beings with fish, human and amphibian-like traits, they are described as having grey-ish green, glossy and slippery skin with white stomachs. They have scaled, ridged backs, as well as webbed and clawed hands and gilled necks. Notably, they have heads similar to that of a fish, with mouths filled with sharp teeth and eyes incapable of blinking.

They move about in an inhuman fashion, by hopping oddly, and occasionally move on all fours. Described as having abhorrent, croaking voices that spoke a language other than English.
