I'm sure many of you have caught a bass around the spawn with a tail that was pretty worn out from fanning the nesting area. By early fall, however, those gnarly tails regenerate, and that's a pretty amazing phenomenon as far as I'm concerned. It kind of makes you wonder why if fish can do it, why can't we regenerate new toes if they get run over by the lawn mower? I recently called my friend Jim Burris from Duke Medical Center to ask a few of these questions, and the answers I got were pretty amazing. Thanks to studies of fish regeneration abilities, people in the future may, in fact, be able to regrow toes that collided with a John Deere.
