This subject contains information from the "Lovecraft Circle" Myth Cycles, and while guided by HPL are not based on his work alone. 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. (HPL: "The Shadow Over Innsmouth")

Description[edit | edit source]

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 hands and gilled necks. Notably, they have a head similar to that of a fish, with eyes incapable of blinking.

They move about in an inhuman fashion, by hopping oddly, and occasionally move on all fours. The narrator, Robert Olmstead, describes them as having abhorrent, croaking voices that spoke a language other than English. Their form was so horrid that their mere appearance caused Robert to lose consciousness for a while. (HPL: "The Shadow Over Innsmouth")

All hybrids are shown coming from a female Deep One and a male human. It is a safety measure based on the fact that both of those possess the limiting growth gene of their own species, otherwise the child would become much larger. It is similar to a liger, a hybrid born from a male lion and a female tigress who never stop growing until their maturity. (EXP: Providence, Alan Moore)

Deep One Hybrids[edit | edit source]


As part of their pact with the Deep Ones, the residents of Innsmouth are forced to interbreed with them. Although the Deep One hybrid offspring are born with the appearance of a normal human being, they gradually assume the appearance of their Deep One ancestors. These traits include:

  • Shrunken/nonexistent ears
  • Glassy, bulging, unblinking eyes
  • Narrow, hairless head
  • Rubbery, blue-gray skin
  • Folds on the neck which eventually become functional gills
  • Webbing between fingers

When the hybrid becomes too obviously non-human, they go into seclusion in ostensibly abandoned buildings until fully capable of living solely underwater. The rate of progression varies with each individual. However, it normally does not reach completion until the human middle age. Once this transformation is complete they are also functionally immortal. Apart from the physical change they also feel a scorn for humanity, an affinity for the Non-Euclidean artwork of the Deep One race, and an increasingly powerful desire to abandon the human world and go to the Deep One city of Y'ha-nthlei. Asenath Waite is a notable Deep One but she was killed before the transformation could finish.

Trivia[edit | edit source]

  • In the role-playing game Call of Cthulhu it is explained that this habit is due to the fact that when an underwater city reaches a certain size, fertility decreases, as the females begin to eat their young.

In popular culture[edit | edit source]


...other beings with wider, stronger, or different range of senses might not only see very differently the things we see, but might see and study whole worlds ...which lie close at hand yet can never be detected with the senses we have. - HPL: From Beyond
