Newly discovered catfish species climbs rocks

Researchers in Venezuela stumbled upon a catfish that "decouples" its pelvis, and uses its suction mouth, to climb like an inch-worm up rocks (MSNBC). Pretty bizarre. And Pound360 is still trying to figure out why a fish would want to climb rocks. Why did this behavior evolve? It's not much, but here's the vague explanation from the MSNBC report: "Climbing could be an advantage to these fishes because of the irregular and sometimes high-flow of streams in these elevations."

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
