Leeches
A Leech's digestive system is very unique. They suck on the blood of mammals. Leech's have 2 mouths. They have a small sucker which contains the mouth at the anterior end of their body and they have a large sucker which is located at the posterior end of the body. They have a crop or pouch in which they could store food for several months. They have 3 jaws set with sharp teeth that make a Y- shaped mark on the flesh of the organism. Their saliva contains a substance that anesthetize the wound area. They store the blood in their crop and have enough to only feed twice a year.
