Additional Facts

Invertebrates are ectotherms (cold-blooded): they warm their bodies by absorbing heat from their surroundings. Most invertebrates live in water or spend at least some part of their life in water.

Some groups of invertebrates live on land. Common examples include worms, insects and spiders. These invertebrates need to have special structures to deal with life on land.

Most invertebrates change form as they grow, going through a process known as metamorphosis.
