Two popular locations in the Galapagos Islands to see marine iguanas that are endemic to the islands and found nowhere else on earth are La Loberia Nature Reserve on San Cristobal Island and Tortuga Bay on Santa Cruz Island.
The area where the beach meets sand dunes are nesting grounds and you will see signs posted to not disturb, especially during March through May which is the breeding season.
The marine iguanas (scientific name is Amblyrhynchus cristatus) feed on underwater algae and seaweed.
They used to be abundant on Santiago Island and elsewhere but the population was decimated by the introduction of non-native pigs, dogs, rats and cats. Common Land Iguanas are listed as ‘vulnerable’ on the IUCN Red List of Threatened Species.
There are seven species of Lava Lizard (Tropidurus) in the Galapagos, with ones with a crest (like a mohawk) found only on San Cristobal. The grey Lava Lizard pictured below is a male, the reddish one a girl; females have a red belly and neck.
