The desert is filled with all sorts of cactuses. I'm not sure what the first one is...but it reminds me of brain coral :) The second one is an agave, looks similar to aloe, some have unique patterns on their leaves. Some cactuses have barbed thorns that stay in you after you accidentally met them, while others have straight thorns that get softer the farther you go up the trunk. The ribbed trunks of the Saguaro are so that they can expand when it rains. The Saguaro can absorb hundreds if not thousands of litres from a good rain over a few days. The Saguaro generally starts it life being sheltered by another plant, once its mature it becomes very efficient at absorbing surrounding moisture from the light rains (10-12" a year) and the tree that once sheltered it, dies.
