What are 5 examples of invertebrates?

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).

Does snake have a backbone?

Snakes need lots of bones so that they can be both strong and flexible. They have a special skull (more on this later!) and they have a very long spine, made up of hundreds of vertebrae (the bones that make up our backbone). They also have hundreds of ribs, almost the whole way down their body, to protect their organs.

Do butterflies have backbones?

All fish share two traits: they live in water and they have a backbone—they are vertebrates.

What animals are invertebrates groups?

Sponges, corals, worms, insects, spiders and crabs are all sub-groups of the invertebrate group - they do not have a backbone. Fish, reptiles, birds, amphibians and mammals are different sub-groups of vertebrates - they all have internal skeletons and backbones.
