Reptiles are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
The marine iguana, also known as the sea iguana, saltwater iguana, or Galápagos marine iguana, is a type of iguana that can only be found in the Galapagos Islands. It is a marine reptile that can forage in the sea for algae, which accounts for nearly all of its diet, making it unique among modern lizards.
Turtles are a type of reptile known as a Testudine, and they have a shell made primarily of their ribs. The Pleurodira and Cryptodira groups of modern turtles are distinguished by the way their heads retract.
