Invertebrates are the most abundant creatures on earth, crawling, flying, floating, or swimming in virtually all of Earth's habitats, from townhouses to tropical rain forests Yet most of us rarely notice them unless they're in our gardens or on our dinner plates.
Invertebrates—creatures without backbones—are nature's unsung heroes, quietly playing vital roles in earth's ecosystems. About 99 percent of all known living species are invertebrates. |
