The Prickly Pear Cactus
One way that the prickly pear cactus [Opuntia spp] survives is by its defense mechanisms. It has branching or fleshy stems that are covered with barbed spines and bristles. The spines are difficult to remove once lodged in someone or something other than the cactus because of the barbs. Both the spines and the bristles are uncomfortable if not downright painful to whatsoever or whomsoever gets in their way.
As much as 90% and more of the weight of a Hudson pear cactus [Cylindropuntia rosea] can be devoted to water related activities. The Hudson pear cactus has stems and branching arms that contract and expand. The flexibility enables the cactus to make room for changing amounts of water and watery products and solutions inside.
