The light green segments of the prickly pear are fleshy and oval to egg-shaped. The segments separate from the plants very easily and attach themselves quickly to clothes or skin. This way, goats, donkeys or other animals transport and spread the segments. Once dropped to the ground, asexual reproduction can take place; a full cactus can grow from a segment. The prickly pear’s yellow flowers are often eaten by iguanas and other lizards.
