Note: In the mouth of bloodsucking leeches are three
convergent, serrated jaws, moved by strong muscles. By
the motion of these jaws a stellate incision is made in
the skin, through which the leech sucks blood till it
is gorged, and then drops off. The stomach has large
pouches on each side to hold the blood. The common
large bloodsucking leech of America (
Macrobdella decora
) is dark olive above, and red below, with black
spots. Many kinds of leeches are parasitic on fishes;
others feed upon worms and mollusks, and have no jaws
for drawing blood. See
Bdelloidea.
Hirudinea, and
Clepsine.
