Jumping Cholla

The Jumping Cholla is found in the southwest desert. Their spines can easily catch on clothing and are hard to get off. Opposed to other cacti, which have solid spines, they have have hollow spines. Their hollow spines attach to things easier when brushed against something than others. When they make contact with something with moisture, like skin, the tips curve locking them self in under the surface. They can grow up to 8 feet tall and produces a pink flower. The cactus wren builds its nest in it. The spikes secures the nest and the wren knows not to touch the spikes.
