What is a leeches life cycle?
Leeches make cocoons in which to deposit their eggs. A leech secretes its cocoon from glands--the cocoon initially encases the leech itself.

Why do leeches eat blood?
The short answer is that leeches need blood to grow and reproduce (make baby leeches). Leeches are worms that live in water or on land and feed by sucking blood from fish, frogs, lizards, birds or, if they get the chance, larger animals like humans. They suck blood because it is a very good food source for them.
