Species: 97% of all known animal species
Invertebrates are animals that have no backbones. They account for 97% of all known animal species. Vertebrates have one phylum (Chordata) that covers Amphibians, Birds, Fish, Mammals, and Reptiles. Invertebrates have over 30 phylum including sponges, cnidarians, flatworms, segmented worms, mollusks, arthropods, insects, centipedes & millipedes, crustaceans, arachnids, and more. Where vertebrates have endoskeletons (typically bony structures with an outer covering), invertebrates have exoskeletons (an external skeleton that supports and protects the animal.) So from the flatworm to the octopus, the stink bug to butterfly, invertebrates are very diverse. Here at Scovill Zoo, you will see all sorts of “free range” invertebrates. Look for ants, butterflies, spiders, bees, and beetles walking, flying, crawling, and standing motionless. We have a few invertebrates in our herpaquarium. We have Emperor Scorpions, Hissing Cockroaches from Madagascar, and tarantula.
