The common side-blotched lizard (Uta stansburiana) is named because both sexes have a prominent blotch on their sides, just behind their front limbs. However, the three different male morphs utilise a different strategy in acquiring mates and compete against each other following a pattern of rock/paper/scissors, where one morph has advantages over another but is outcompeted by the third.
