Galapagos Marine Iguanas, Puerto Ayora, Santa Cruz Island, Galápagos Islands, Ecuador, South America.

Galapagos Marine Iguanas (Amblyrhynchus cristatus) bask at Puerto Ayora, capitol of Santa Cruz Island and the largest town in the Galápagos Islands, Ecuador, South America. The Marine Iguana is the world’s only sea-going lizard and is found only on the Galapagos Islands (spread throughout the archipelago). They feed almost exclusively on marine algae, expelling the excess salt from nasal glands while basking in the sun, coating their faces with white. Marine Iguanas live on the rocky shore or sometimes on mangrove beaches or marshes. Most adults are black, some grey, and the young have a lighter colored dorsal stripe. The somber tones allow the species to rapidly absorb the warm rays of the sun to minimize the period of lethargy after emerging from the frigid water, which is cooled by the Humboldt Current. Breeding-season adult males on the southern islands are the most colorful and will acquire reddish and teal-green colors, while Santa Cruz males are brick red and black, and Fernandina males are brick red and dull greenish.
