Australia’s frilled lizard, Chlamydosaurus kingii, is famous for its oversized neck flap, which stands to attention like a satellite dish around its head when it feels threatened. To deter attackers, the animals also hiss intensely–and if those antics don’t do the trick, they turn to another time-tested strategy: running. The lizards flee from predators with wild abandon, legs churning and mouth agape in almost comical fashion, until they reach the safety of the nearest tree.
The marine iguana (Amblyrhynchus cristatus), also known as the Galápagos marine iguana, is a species of iguana found only on the Galápagos Islands (Ecuador) that has the ability, unique among modern lizards, to forage in the sea, making it a marine reptile. This iguana feeds almost exclusively on algae and large males dive to find this food source, while females and smaller males feed during low tide in the intertidal zone. They mainly live in colonies on rocky shores where they warm after visiting the relatively cold water or intertidal zone, but can also be seen in marshes, mangrove and beaches.
