Photograph by @Thomas Peschak The Mystery of the Shrunken Iguana. In lean times, when food is scarce Marine iguanas are able to shrink their skeleton and reduce their size by up to 20%. Smaller animals require less energy and the odds of surviving tough times increases. When seaweed food becomes abundant again their skeletons regrow. Shot on assignment for @ナショナルジオグラフィック Please follow @Thomas Peschak for more photographs of these #oceangodzillas
