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.
Some insects go through stages in their life, and the early stage is the larval stage. Larvae of creatures like butterflies tend to be crawling things with no wings that spend all their time eating and growing. When they are big enough, they change into flying insects.
Many different creatures have a larval stage that is so different to the adult form that you would never know they were the same creature unless you saw it change.

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.
Scientific name: lemmus lemmus
