"Originating in Greece, the Hippocampus has the head and forequarters of a horse and the tail and hindquarters of a giant fish. Though the species is usually to be found in the Mediterranean, a superb blue roan specimen was caught by merpeople off the shores of Scotland in 1949 and subsequently domesticated by them. The Hippocampus lays large, semi-transparent eggs through which the Tadfoal may be seen."

The Hippocampus was a magical water beast with the head and forequarters of a horse, and the tail and hindquarters of a giant fish.[1]


Originally from Greece, it was generally found in the Mediterranean, although a blue roan specimen was caught by Merpeople off the coast of Scotland in 1949 and domesticated.[1]

The Hippocampus laid large, semi-transparent eggs through which the young hippocampus, known as a Tadfoal, could be seen.[1]


  • Hippocampus is derived from the words "hippos" means "horse" and "kampos" means "sea monster".
  • The Hippocamp or Hippocampus, like many creatures in the Harry Potter series, is derived from Greek mythology. A Hippocampus-like creature can be seen in the painting "The Chariot of Poseidon".[2]
  • Hippocampus also refers to a major component of the brains of humans and other mammals. It is what enables the conscious short term memory, and was famously removed from Henry Molaison, when a doctor suspected that removing it would cure his epilepsy.[3]
