Detailed explanation-1: -invertebrate, any animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates. More than 90 percent of all living animal species are invertebrates.
Detailed explanation-2: -HOW DO ANIMALS SURVIVE WITHOUT BONES? Insects, crustaceans, and many other invertebrates have a hard outer case called an exoskeleton. This protects them against blows and predators, and keeps them from drying out.
Detailed explanation-3: -Invertebrates do not have a skeleton or spinal column. We have three main groups of invertebrates: arthropods, mollusc and worms. 8.
Detailed explanation-4: -An invertebrate is a cold-blooded animal with no backbone. Invertebrates can live on land-like insects, spiders, and worms-or in water. Marine invertebrates include crustaceans (such as crabs and lobsters), mollusks (such as squids and clams), and coral.
Detailed explanation-5: -Invertebrates can have a skeleton outside their bodies called an exoskeleton, while some invertebrates have no skeleton at all!
