There are lots. Gryphons, manticores, basilisks, chimeras, dragons, ogres, elves, werewolves, vampires, zombies, etc.
Manticores have the face, ears and eyes of a man, the body of a lion and a scorpion's tail. (in some depictions they also have wings of a bat) Chimeras have the head and forelegs of a lion, the body and backlegs of a goat (they also have a goat's head in the back, just where the lion part ends) and a serpent as a tail.
No they do not exist, but are mythical creatures dreamed up by man. As to why we would have to say that they were to frighten people for some reason or other.
