Very fast, we saw this one fishing. I told my gf to hold her lure by it to give a size reference. it was gone in a flash and she damn near jumped into the lake I thankfully had my 400mm lens on so I was plenty far away or I woulda been with her lol. They like to hang out in the shithouse, I'd rather brave the woods with a million Mosquitos then be on the shitter defenseless with one of those bastards in there.
