Skeleton
The presence of a skeleton, and where it is located, is a characteristic for animals. They can have no skeleton/hydrostatic skeleton, a exoskeleton (skeleton is on the outside) or endoskeleton

Slide 3 - Tekstslide

Animal phyla with hydrostatic skeleton

Slide 4 - Woordweb

Animal phyla with exoskeleton

Slide 5 - Woordweb

Animal phyla with endoskeleton

Slide 6 - Woordweb

Moulting
Arthropods have a exoskeleton, but they can still grow. This means they can grow out of their ''skin'', and they need to exit it. This is called moulting
An exoskeleton is made out of chitin, which is both strong and flexible.
