The hippocampus or hippocamp, also hippokampos (plural: hippocampi or hippocamps; Ancient Greek: ἱππόκαμπος, from ἵππος, 'horse', and κάμπος, 'sea monster'[1]), often called a sea-horse[2] in English,[citation needed] is a mythological creature shared by Phoenician,[3] Etruscan, Pictish, Roman and Greek mythology, though its name has a Greek origin. The hippocampus has typically been depicted as having the upper body of a horse with the lower body of a fish.
