EGG
-Leeches make cocoons in which to deposit their eggs. A leech secretes its cocoon from glands--the cocoon initially encases the leech itself. When the cocoon slips off the leech’s body, the fertilized eggs attach to the cocoon and go with it. Leeches attach their cocoons to substrates such as rocks or plants.
