These Lizards Have a Hot Trick to Escape Hungry Snakes On some Japanese islands where lizards live, the ones that fear predators have higher body temperatures that help them run faster.

Every year since, he has taken the eight-hour ferry ride from Tokyo southeast to this cluster of volcanic islands to pursue a passion he has had since childhood: catching lizards. A single lizard species, Okada’s five-lined skink, dominates all of Izu’s nine major islands, while its major predator, the Japanese four-lined rat snake is found on most, but not all, of these islands. This makes the islands a bit like the Galapagos, where Charles Darwin first described how selective pressures in this case those predatory snakes may shape the islands’ lizards
