Ichthyocentaurs the Sea God Centaurs

In Greek mythology ichthyocentaurs were a pair of centaurine sea-gods with the upper body of a man, the lower front of a horse, and the tail of a fish. Also, they wore lobster-claw horns. The two sea-gods were named Bythos ("Sea-Depths" or "Depth of Profundity") and Aphros ("Sea-Foam"). They were half-brothers of the wise centaur Cheiron and the sons of Poseidon and the sea goddess Amphitrite.

These two sea-gods, though little remembered, were set in the sky as the astronomical constellation Pisces.

The sea-centaurs were probably derived from the divine fish of Syrian mythology that carried Astarte ashore following her watery birth.
