Colymbosathon ecplecticos

It means "swimmer with a large penis" in Greek, apparently.
From The New York Times:

"A 425-million-year-old fossil found in Herefordshire, England, may be the oldest record of an animal that is unarguably male. Scientists report today in the journal Science that the tiny crustacean, only two-tenths of an inch long, had an unmistakable penis."

So, he's only two-tenths of an inch long. Hmmn. But he's called Colymbosathon ecplecticos. I was about to note that's not the first time a guy has, uh, exaggerated--except that apparently it is the first time.

Something else that women would find all too familiar:

"It also offers a striking example of evolution almost standing still. "This," Dr. Siveter said, "is an animal whose basic ground plan hasn't changed in 425 million years." It evolved hardly at all "(my emphasis).

No word on whether or not he sat around all day in boxers and an undershirt, watching tv, and scratching himself. But it wouldn't surprise me.
