Zodiak sign Capricornus is strange creature half goat, half fish.
Sumerians and Babylonians had an affinity to amphibian entities.
Greeks called this constellation Pan. He usually spent his time chasing after women, and taking a nap. He loved to play pranks on mortals, frightening people with his loud shouts. (this is the origin of "panic")
One of his sons was Crotus, identified as the constellation Sagittarius.
Pan helped the gods against the Titans, he blew a conch shell to put the enemy to flight. Later he shouted a warning to the gods, that the monster Typhon, sent by Gaia (Mother Earth), was approaching. At his suggestion, the gods turned themselves to animals, to escape from Typhon. Pan took his refuge in a river, transforming his lower part of his body to a fish. Zeus fought with Typhon, but the monster pulled his sinews out of his body, leaving Zeus crippled.
Hermes and Pan replaced the sinews, allowing Zeus his revenge. Typhon was cut down with thunderbolts and finally buried under Mount Etna.
