Ketos

In Greek mythology, a Cetus is a large sea monster. Perseus slew a cetus to save Andromeda from being sacrificed to it. Later, before the Trojan War, Heracles also killed one to rescue Hesione. The term cetacean derives from cetus. In Greek art, ceti were depicted as serpentine fish. The name of the mythological figure Ceto is derived from kētos. The name of the constellation Cetus also derives from this word.
