Ichthyocentaurs

In late Greek mythology ichthyocentaurs were a race of centaurine sea-gods with the upper body of a human, the lower front of a horse, the tail of a fish, and lobster-claw horns on their heads. The sea-centaurs were probably derived from the divine fish of Syrian mythology. Ichthyocentaurs upper bodies took the form of a human torso down to the hips, and the lower that of a fish, with two horse legs protruding from this intersection. They were sometimes depicted with lobster claw horns. The two named ichthyocentaurs were Aphros 'Sea Foam' and Bythos. 'Sea Depths'

They were half-brothers of Chiron and the sons of the Titan Cronus and Nymph Philyra.

Bythos and Aphros

Some ichthyocentaurs wore crowns while others were depicted with horns. The best-known members of this race were Aphros and Bythos. These two sea-gods, though little remembered, were set in the sky as the astronomical constellation Pisces.
