Hippocampus

The hippocampus is a beast with the head and forequarters of a horse and the tail and hindquarters of a giant fish, making it somewhat similar in appearance to an oversized seahorse. Although it is generally found in the Mediterranean, a blue roan specimen was caught by Merpeople off the coast of Scotland in 1949 and domesticated.

Hippocampi lay large, semi-transparent eggs through which the young tadfoal can be seen.
