Look at just how handsome these sunbathing fellas are! The marine iguana (Amblyrhynchus cristatus) is found only on the Galápagos Islands and has the unique ability to live and forage in the sea, making it a marine reptile. The species has the 'vulnerable' status as its threatened by predation by introduced species such as cats and dogs, which prey particularly upon its young. Ah Darwin described them as disgusting clumsy Lizards. Boo.
The Pinta Island tortoise (Chelonoidis nigra abingdonii) was a subspecies of Galápagos tortoise native to Ecuador's Pinta Island. The fellow on the postcard was called Lonesome George and was the last known individual of the subspecies - he was born before 1912 and died in June 2012. Sadly, over the decades all attempts at mating Lonesome George had been unsuccessful...Its a sad story isnt it? :((
