Ichthyocentaurs (or Ikhthyokentauroi) were marine centaurs. They possessed the upper bodies of men, the lower bodies of horses and a serpentine fish tail. They were sometimes depicted with lobster claw horns.
The two named ichthyocentaurs were Aphros ("Sea Foam") and Bythos ("Sea Depths"). They were usually portrayed alongside Aphrodite at her birth. They possibly had their origins in Mesopotamian mythology as two marine gods associated with Astarte. They were later set in the sky as the constellation Pisces.
