Detailed explanation-1: -Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.
Detailed explanation-2: -As invertebrates lack an internal skeletal structure, they sometimes have an external skeleton that protects their soft bodies called an “exoskeleton.” In general, invertebrate success often comes from their ability to reproduce extremely quickly, unlike many vertebrates who take years to become fully grown.
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: -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-5: -Flying fish are just one impressive example of a species with an endoskeleton, an internal skeleton typically made of bone and found in vertebrates, including mammals, birds, reptiles, amphibians, and fish.
