Ceto
Ceto (Κητώ) was a sea-monster, the daughter of Pontus ("Sea") and Gaea ("Earth"). Ceto was the sister of the sea gods Nereus and Phorcys.
Not much detail is known about Ceto except that she was mother of several monstrous offspring by her brother Phorcys. Ceto was the mother of Ladon, the Gorgons (except Medusa), the Graeae, and possibly of Echidna.
