Animals with a backbone
|
Detailed explanation-1: -Animals without backbones are called invertebrates. They range from well known animals such as jellyfish, corals, slugs, snails, mussels, octopuses, crabs, shrimps, spiders, butterflies and beetles to much less well known animals such as flatworms, tapeworms, siphunculids, sea-mats and ticks.
Detailed explanation-2: -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-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: -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.
