Some excerpts:
By the time Dr. Siddall joined the museum in 1999, the evolution of leeches had become his chief obsession. . . . To collect leeches, Dr. Siddall and his colleagues take off their shoes, roll up their pants and wade into the water, even if its waist-high muck [is] full of electric fish. "You can't set traps for leeches," Dr. Siddall said. "We are always the bait . . ."As queasy as this all might make you, I think it's a fascinating article. And the close-ups of the leech in action on some human skin? Call the resident teen or tween in for a look. I'll bet you you get a "cool!"Leeches appear to have evolved their own partnerships [with bacteria] . . . It is particularly tough to study these bacteria, because scientists need to find leeches with big bacteria-housing organs to dissect. It turns out that some of the biggest are in a species that lives just on the rear end of the hippopotamus. . . .

Yeah that's not weird at all...the guy goes out and collects leaches for a living...but if he's doing it for science I guess it's okay...but I don't know about the rest of us...but i'd rather not have some amphibian (?) attatched to my wrist while I was in the hospital trying to get better...
Doctor: let's see how we're doing here...Whoops! Left that leach on to long!
