No other extant lizard species is marine, but several are partially aquatic and feed on freshwater organisms. Extinct in the Wild.
It is very difficult to eradicate invasive species from islands, so this problem is likely to continue to threaten marine iguana populations. The Marine Iguana You can keep your tortoises, boobys, sea lions and sharks: according to many respected biologists, the most remarkable animal in all of Galapagos is the mild-mannered marine iguana.

Just about every rocky shoreline in the Galapagos Islands is home to the marine iguana (Amblyrhynchus cristatus), the only sea-going lizard in the world. Their primary predators are birds, such as hawks, owls and herons when they are young, and the Galapagos hawk when they are adults.
No reasonable doubt that the last individual has died. Marine iguanas are endemic to the Galapagos Islands and are the only marine lizard species in the world.
The current study investigated the impact of ecotourism, a seemingly low-level human disturbance, on stress responsiveness and specific fitness-related immune measures in the Galapagos marine iguana (Amblyrhynchus cristatus). Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. Iguanas are one of the most amazing reptiles in the world, from their deep dives in the Galapagos, to high speed chases with snakes, to their third eye, the Iguana is deserving of the title.
