The labrador retriever is a very popular breed of gun dog. They were originally developed to retrieve birds after they were shot.
Labradors come in three main colours - yellow, black and chocolate.
Labradors are a gentle, intelligent dog and make excellent family pets. They can be trained to be helping dogs, and are used as guide dogs for blind people.

Leeches are in the same family as earthworms. Not all leeches are bloodsuckers, but the ones people are most familiar with are. They grow to around 2-5cm long but some species reach 30cm. Leeches live in damp, swampy areas.
Leeches have adapted one end of them into a sucker, so they can attach to a host. They inject anaesthetic in as they bite, so the host cannot feel them, and then an anti-clotting agent so the host's blood flows freely. Leeches stay stuck to their host until they are full, then they drop off.

A lerp is a protective cover made by the larvae of some kinds of insects. Lerps are made from sugary liquid that the larvae make. Once it is dry, it is hard and crystalline.
