Only a few are parasites on humans
Leeches that attach to humans are not found in fast moving water or riffle areas
Many are scavengers or feed on other invertebrates
Suckers at both ends are used for attachment, feeding, and locomotion
They swim gracefully and quickly in an up-and-down motion
They move by attaching suckers from end to end
