Galapagos Islands, Ecuador
Marine iguanas in Galapagos amass in massive clusters atop the lava rocks that are ubiquitous throughout the islands. They have a face and form that from Darwin’s perspective are features that only a mother could love; but they have adapted into incredible creatures. They are cold-blooded, so they warm their bodies in the sun before diving into the water to feed on algae, and then repeat the process after feeding. They raise their body temperatures up to 97 degrees before heading underwater where they can loose up to 50 degrees before returning to the surface. They have also adapted to get rid of the high level of salt in their diet by sneezing the salt out through their nostrils.
