Detailed explanation-1: -Invertebrates: The animals that do not possess backbones are known as vertebrates. These animals are mostly soft-bodied. For example Earthworms, snails, sponges, etc.

Detailed explanation-2: -An invertebrate is an animal without a backbone. In fact, invertebrates don’t have any any bones at all! Invertebrates that you may be familiar with include spiders, worms, snails, lobsters, crabs and insects like butterflies. However, humans and other animals with backbones are vertebrates.

Detailed explanation-3: -Invertebrates do not have backbones or internal skeletons, but some have hard coverings. Insects, spiders, worms, snails, and most ocean animals are invertebrates.

Detailed explanation-4: -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.
