2. (Zool.) Any one of numerous genera and species of annulose
worms, belonging to the order {Hirudinea}, or Bdelloidea,
esp. those species used in medicine, as {Hirudo
medicinalis} of Europe, and allied species.
[1913 Webster]

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}.
[1913 Webster]

leech 1. n. (Also leecher.) Among BBS types, crackers and
warez d00dz, one who consumes knowledge without
generating new software, cracks, or techniques. BBS culture specifically
defines a leech as someone who downloads files with few or no uploads in
return, and who does not contribute to the message section. Cracker
culture extends this definition to someone (a lamer,
usually) who constantly presses informed sources for information and/or
assistance, but has nothing to contribute. See
troughie.
