The Marine Iguana

The marine iguana (scientific name amblyrhynchus cristatus) is a subspecies of iguana that inhabits the waters of the Galapagos. It can grow between 2 and 5.6 feet long. One of its main nesting beaches is one in Puerto Villamil, Isabela Island that is a major tourist attraction. It can also be found resting on other rocky shores.

The marine iguana is classified as a Vulnerable species. It is this close to becoming extinct for two reasons. The first reason is that it is hunted by the cats, rats, dogs, and pigs that have been introduced to its habitat by humans. The second reason is that rising sea levels and air temperatures have been negatively impacting its nesting beaches, the development of its eggs, and its ability to regulate its body temperature while it's on land.
