The name "starfish" and "mountain lion" are both misnomers. A starfish is not a fish and a mountain lion is not a lion. So I guess they are similar in that their names are misleading. Although a mountain lion is much more related to a lion than a starfish is to a fish. Mountain lions share the same Family name with lions, Felidae.
