In Greek mythology, Ceto, or Keto (sea monster) was a hideous aquatic monster, a daughter of Gaia and Pontus.

She was the personification of the dangers of the sea, unknown terrors and bizarre creatures. Eventually, the word "ceto" became simple shorthand for any sea monster. It is still used in this way. Her husband was Phorcys and they had many children, collectively known as the Phorcydes.
