Amblyrhynchus cristatus

"The marine iguana is found on the volcanic islands of the Galapagos. Many of the islands have steep rock cliffs, low rock ledges and intertidal flats. A. cristatus needs access to the ocean and a sandy area to lay eggs. They evolved in a habitat that is limited in predators. On Santa Fe an island in the Galapagos the predator are hawks, short-eared owls, snakes, hawk-fish, and crabs. With so few natural predators the marine iguana is very vulnerable to feral predators such as rats, dogs and cats."
