Invertebrates are animals without backbones.

They are cold-blooded and warm their body by

absorbing heat from their surroundings.

Invertebrates are eukaryotic because they contain

complex structures enclosed within membranes.

Invertebrates are multicellular, which means that they

are organisms that contain more than one cell.

Invertebrates don’t have cells walls because they are all

animals and animals can not have cell walls.

Invertebrates can’t make their own food, thus they are

heterotrophic. They feed off other things to get their

energy.
