Answer 2

Answer and Explanation:

Invertebrates are animals with no backbone. More than 90% of the animals are invertebrates among the estimated 15-30 million animal species. Invertebrates exist about anywhere. These have been found in the driest of deserts, high reaches of the atmosphere and canopies of wettest rainforests. They also exist in the frozen Antarctic or under deepest oceans.

Familiar examples of invertebrates include arthropods (insects, arachnids, crustaceans, and myriapods), mollusks (chitons, snail, bivalves, squids, and octopuses), annelid (earthworms and leeches), and cnidarians (hydras, jellyfishes, sea anemones, and corals).
