1-The Hippocampus, a half-fish, half-horse monster with the head of a horse and the tail of a dolphin (or rather, a horse's tail or a snake's tail), some with forelegs and some without, with webbing between its paws and fins on its back, was said to be the mount of Neptune, the god of the sea, and is depicted on medieval coats of arms.
2- A flesh-eating monster is rumored to be in South Africa, killing nine people in 1997 alone. The horse-headed, fish-bodied monster allegedly pulls its prey down into the water and then eats away its head, face and brain tissue.
3- The Horsehead Fishtail Sea Monster is a large monster native to Greece. It has the head and front body of a horse and a fish-shaped tail and back body. This monster can be seen frequently in the Mediterranean Sea. 1949, a very good-looking blue sandy-haired species of Horsehead and Fishtail Sea Monster was captured by mermaids from the coast of Scotland, and then tamed by them. The eggs laid by the horsetail sea monster are so large and translucent that the baby horsetail sea monster can be seen through them.
