When you were younger, you may have learned about a group of organisms called minibeasts. Animals commonly called minibeasts include caterpillars, worms and spiders.
Minibeasts are actually called invertebrates by scientists. Many invertebrates, like spiders and insects, all have a tough outer case to support their bodies (instead of a backbone, like we have). This case is called an exoskeleton.
From now on, we will no longer use the term minibeasts, instead we will call them by their proper scientific name: INVERTEBRATES.
Invertebrates get around in all sorts of ways. They can: fly, slither, swim and walk. Let's have a closer look.
