The most popular leech, because of its use in the medical field is the Hirudo medcinalis. After attaching to a host, the leech can fill itself in about 45 minutes, expanding up to twelve times its original size in blood! On that full belly the leech can survive up to 6 months. Giving the optimal conditions... a leech only feeds twice a year!

Most leeches are fluid feeders. Blood-sucking leeches drink as much blood as they can from their victims. This blood is stored in special sacs at the side of their intestine and digested later. Most can consume 3 times their own body weight in one meal. This allows the leech to survive long periods without food.
