Unique among modern lizards , it is a marine reptile that has the ability to forage in the sea for algae , which makes up almost all of its diet. [ 5 ]
Marine iguana: marine iguanas live only on the Galápagos Islands and are not fully adapted to marine life. Although they feed exclusively on marine plants and spend a good deal of their time in the water, they do nest on land and need to bask in the sun to reach their ideal body temperature; they are thus also subject to terrestrial predators.
The marine iguana is also extremely unusual, since it is the only iguana adapted to life in the sea. Land iguanas, lava lizards, geckos and harmless snakes are also found on the islands. The large number and range of birds is also of interest to scientists and tourists. Around 56 species live in the archipelago, of which 27 are found only in ...
Marine Iguanas are the only marine lizard species in the world found only in the Galápagos Islands. They can dive as deep as 30m (98 feet) and hold their breath for 30-40 minutes.
Marine iguanas have sharp claws and are able to grip rock under seawater and eat seaweed, whereas land iguanas lack sharp claws, making them unable to climb the cacti that are their staple foods. Hybrid iguanas have sharp claws and can climb on cacti and also eat seaweed underwater. The hybrid iguana can survive in both sea and land environments.
Plant parts can be hard to digest, and, as they get closer to adulthood, juvenile iguanas eat faeces from adults to acquire the microflora necessary for their transition to a plant-based diet. Perhaps the most herbivorous species is the marine iguana which dives 15 m (49 ft) to forage for algae, kelp and other marine plants. Some non ...
Most iguanas are arboreal, living in trees, but some species tend to be more terrestrial, which means they prefer the ground. Iguanas are typically herbivores and their diets vary based on what plant life is available within their habitat. Iguanas across many species remain oviparious, and exhibit little to no parental care when their eggs ...
The marine iguana (Amblyrhynchus cristatus) is also among the largest iguanas in the world, [78] and the largest reptile on Galapagos Islands after the Galapagos land iguana, not including turtles reaching a maximum total length of 1.4 m (4.59 ft), a SVL of from 12 till 56 cm (from 4.72 till 22 in) [82] [83] and a mass of from 1 to 12 kg (2.2 ...
