Prickly Pear Cactus
There are 28 different species of cacti in the monument, ranging from the giant saguaro to the miniature pincushion. These cacti are all highly adapted to survive in the dry and unpredictable desert. They use spines for protection and shade, thick skin and pulp to preserve water, unique pathways of photosynthesis at night, and hidden under their skin are delicate to sturdy wooden frames holding them together.

Prickly pear cacti typically grow with flat, rounded platyclades that are armed with two kinds of spines; large, smooth, fixed spines and small, hairlike spines called glochids that easily penetrate skin and detach from the plant. Many types of prickly pears grow into dense, tangled structures.
