There is no such thing as an "average" cactus, because there are many different kinds, and the cacti may be big or small, young or old. Most cacti will have thousands of spikes on them. Big cacti may have tens of thousands of spikes.

What are the spines on the cactus and why are they important?

ShelchavCactus spines are actually modified leaves. It helps if you think of cactus as a large stem with leaves (spines). One of the main functions of the spines is fairly obvious, which is to protect cacti from predators such as animals and people. Spines will turn away most animals, but there are a few that are not put off by prickly spines. These animals include javelina, pack rats, desert tortoises and even Desert Bighorn sheep.Saguaro (Carnegiea gigantea)A major function of cactus spines serve to provide protection for the cactus from the sun. At first, it is hard to believe that tiny cactus spines offer any real protection from the intense desert sun. But when you consider that a cactus can have thousands of spines and each spine provides a small amount of shade and multiply that by 1,000 - well it becomes easier to believe that spines really do offer some protection from the sun for the skin of the cactus.
