The Pegasus was the mount of the hero Bellephron. Together they destroyed the Chimera. This flying horse gave him great agility to dodge the many blows from the Chimera. Later Bellephron thought that he was as great as the gods and rode to heaven on the back of Pegasus.
The Hippocampus is a glamourous animal of the ocean. They were the pets of the sea and horse god, Poseidon and would draw his chariot across the sea. They have the upper-half of a horse and the lower-half of a fish or dolphin. They love being out at sea and are fairly strong creatures with lots of stamina. They are devotional to their god and like to spend time with their fellow Hippocampi.
