The invertebrates are a huge group of animals that include virtually everything except those with backbones. Technically, the bones in our backs (i.e., backbones) are referred to as "vertebra," and animals with vertebra are called "Vertebrates," while those without vertebra are called "In-vertebrates" (where "in-" means not or without). Invertebrates are an extremely important group of organisms in the desert (and everywhere else for that matter), and desert ecosystems wouldn't function without them.

There are far too many invertebrates in the Mojave Desert to list them all. My intent here is to list the major groups and a few of the more common, conspicuous, and interesting invertebrate life forms within each group. While this website celebrates the lives of these creatures, they do belong out-of-doors. If you have trouble with unwelcome guests in your home, consider contacting Fischer's Pest Control.
