BEST ANIMAL PHOTOS OF 2017-Iguanas

Two marine iguanas seem unfazed by the presence of one of their mummified brethren, dead likely from starvation, on Isla Fernandina. Endemic to the Galápagos, these raccoon-size lizards forage for algae along the shore; larger males dive into the ocean. The algae they eat die in warm water, rendering Darwin’s “imps of darkness” susceptible to climate change.
