All vertebrates have an internal skeleton inside the body that gives them their distinctive shape and supports the body.

Endoskeleton

Most invertebrates have a hard covering outside their body that supports the body and protects its internal organs.

ExoskeletonSome invertebrates have a fluid-filled skeleton that consists of liquids under pressure that acts on the inner walls to support the body.

Hydrostatic skeleton

Supported by its backbone. Supported by the surrounding water (buoyancy) Have body limbs for walking, running or flying Have streamlined bodies to move easily in water
