Marine Iguanas: The Sea Lizard of the Galápagos Islands

Jennifer and Amber Season 3 Episode 10

Marine Iguanas are the only lizards currently on Earth that go into the ocean. Known as sea iguana or saltwater iguana, they are a species found only on the Galápagos Islands. These unique lizards forage for algae, which make up almost all of its diet, when not sunbathing on the shore. How and why did Marine Iguanas evolve only on these tiny islands in the middle of the ocean? Well, it’s complicated and exclusive to these islands loved by Charles Darwin. 

In The Good The Bad The News
A box of human heads was stolen in Denver. The heads were being transported for medical research, and no leads on who took them, or why. 
EPA enforcement of environmental laws has seriously declined, because that’s what happens when we cut their budget, and this is bad news for the environment. 
Break through discovery allows for plastic to be recycled at room temperature indefinitely. 
International plastic treaty in the works. This treaty would tackle production and packaging design .

Marine Iguanas were described as ugly when first ‘discovered’ by Europeans. This was mostly due to their dark colors that they evolved to more efficiently warm up after leaving the cool ocean water. Their special organ that allows them to expel sea salt leaving a crust of salt on their heads probably didn’t help their case either. 
Marine Iguanas have evolved to fill a very specific niche that is found nowhere else on this planet. Any changes to this environment, specifically those caused by humans, could cause this remarkable species to disappear.
