Deep Ones

Deep Ones are amphibious, marine-dwelling humanoids, having "fishy" and "froglike" traits. They are powerfully-built, effective jumpers and strong swimmers, and are said to have colonies in the American northeast coast, the British Isles, areas of Northern Europe, and even Antarctica, although it is not known if they have remained the same species. They are presumably unaging.
