The marine iguana is an iguana found only on the Galápagos Islands that has the ability, unique among modern lizards, to forage in the sea, making it a marine reptile.
On the Galapagos, adult marine iguanas have little to fear. For their young however, they risk life and limb right from the moment of birth.The hatching of these baby marine iguanas is the best and easiest chance for a quick meal that the snakes will see all year.
Unfortunately for the iguanas they have no idea the snakes even exist, in fact, all they know is they need to get to the water.
As an ectothermic animal, the marine iguana can spend only a limited time in cold water diving for algae. Afterwards it basks in the sun to warm up. Until it can do so it is unable to move effectively, making it vulnerable to predation.
