These blossoms may look beautiful and inviting, but look closer. Those
thorns are even more terrifying and have a bite much more severe than even
the rose. Due to the low precipitation in the desert, cactus plants have
developed a wicked way to protect themselves from predators wanting to
eat them for their moisture content. And if you've ever seen a cowboy wearing
chaps while riding a horse, this is one of the reasons why. You don't want
to brush up along one of these plants with only levis, while riding along
at a full gallop.
