Deep One

Deep One

The Deep Ones are creatures in the Cthulhu Mythos of H. P. Lovecraft. The beings first appeared in Lovecraft's novella "The Shadow Over Innsmouth" (1931), but were already hinted at in the early short story "Dagon". The Deep Ones are a race of fish-frog-like, ocean-dwelling creatures with an affinity for mating with humans which occurs regularly along the coast.

Numerous Mythos elements are associated with the Deep Ones, including the legendary town of Innsmouth, the undersea city of Y'ha-nthlei, the Esoteric Order of Dagon, and the beings known as Father Dagon and Mother Hydra. After their debut in Lovecraft's tale, the sea-dwelling creatures resurfaced in the works of other authors, especially August Derleth.
