Key Stage 2

Meaning

An invertebrate is an animal without a backbone.

About Vertebrates

There are many different kinds of invertebrate animals.

Some invertebrates have exoskeletons, which is a hard bony shell on the outside.

Some invertebrates have no bones at all and just use muscles to move.

Examples

None of these animals have a backbone so they are examples of invertebrates.

Flies insects which are a type of invertebrate with 6 jointed legs.	Spiders are arachnids which are a type of invertebrate with 8 jointed legs.	Earthworms are worms which are a type of invertebrate with a long tube like body and no legs.	Snails are molluscs which are a type of invertebrate with a muscular body. They also sometimes have a shell.	Crabs are crustaceans which are a type of invertebrate with muscular bodies with an exoskeleton and 8 jointed legs.
