A leech is an annelid or segmented worm related to earthworms. Most are aquatic although there are land leeches in the tropics. Some leeches are blood sucking parasites bu â¦ t others are predators.
All leeches have 2 sucking discs (one at each end). The larger disc is located at the tail which is used most of the time to hold on to things. The smaller disc is the mouth area. Most anglers hook a leech around the large disc area. The large disc and small disc on a leech are also used in the reproduction process because they contain both male and female reproductive organs. There may be slight color variations from either a light brown to olive green but most are blackish.
