Every animal has a habitat where it can find food and shelter and have its babies.

But there is one group of creatures whose habitats are not forests, seas or deserts.

Instead they live on or in the bodies of other animals - in skin, hair, fur, feathers, blood, guts, livers, hearts and lungs.

They are parasites! Uncover the secrets of their amazing life - cycles and dare yourself not to scratch or groan as you read...then give in; it's impossible!

Short written sections with creepy-crawly diagrams and comic strips make this information book engaging and accessible for young minds.
