Leeches 2

Most species of leech are terrestrial or freshwater, while a minority are marine or parasitic. Those leeches which are aquatic feed on blood or eat small animals including snails, worms and insects. Leeches acquire blood by attaching to a host with strong suckers. A small Y-shaped incision is made and an anticoagulent prohibits the blood from clotting as blood flow increases. MORE! [BM] {EB}
