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.
Most earthworms and leeches are hermaphroditic with both male and female gonads. Polychaetes usually have separate sexes; many polychaetes hatch into a particular type of planktonic larva, the trochophore, which later metamorphoses into a juvenile annelid. Some polychaetes, however, can reproduce asexually, by budding.
