What is list of animals without backbones?

Answer

Many animals lack a backbone. Animals that do not have a backbone are called invertebrates. Most invertebrates are insects or crustaceans. According to stlzoo.org, the list of animals without a backbone includes all crustaceans (shrimp, crabs, lobsters), centipedes, ants, bees, wasps, termites, flies, grasshoppers, katydids, crickets, cockroaches, mantises, stick insects, beetles, butterflies, moths, silkworms, water bugs, scorpions, millipedes, snails, slugs, octopuses, spiders, worms, and leeches. The list of all animals without a backbone is much larger, of course.
