The fish-scale gecko has a freaky way of eluding danger. When snatched by an attacker, it rips off its scales and skin so it can slip away unscathed. Basically, it streaks to survive.
“It looks like a fish until you grab it, and then it looks like a naked chicken breast,” said Mark D. Scherz, a doctoral candidate at Ludwig Maximilian University of Munich. The torn-away scales reveal the gecko’s pink flesh, and through its translucent tissue you can see its spine and blood vessels. “It’s bizarre, it’s really surprising, and it’s quite uncomfortable when you see them,” he said.
It may seem like a gruesome getaway, but it doesn’t hurt the lizard. It loses its skin and scales with extreme ease and regenerates them in full a few weeks later. The new scales grow in with a different pattern than the previous ones, but other than that are nearly indistinguishable from the originals.
