Desert Hairy Scorpion

Arthropods (insects, centipedes, scorpions, etc.) are well represented in the SonoranDesert, but did you know the desert depends on them to keep it healthy?  These tiny creatures help regulate the populations of herbivores, predators, parasites and the flora, keeping the ecosystem—all ecosystems—in balance.
