Green Sea Turtle
EndangeredThe green sea turtle is one of the largest sea turtles and the only herbivorous species among them. They are named not for the color of their shells, but for the greenish color of their subdermal fat, which is stained by their diet of seagrasses and algae. Green sea turtles migrate incredibly long distances between feeding grounds and the nesting beaches where they were born. Their streamlined shells and paddle-like flippers make them exceptionally graceful swimmers.

Komodo Dragon
EndangeredThe Komodo Dragon is the largest living species of lizard on Earth, inhabiting a few Indonesian islands. Reaching lengths of up to 3 meters (10 feet), it is a dominant apex predator in its harsh, dry island ecosystem. Armed with serrated teeth, a venomous bite, and a highly sensitive sense of smell, Komodo dragons can hunt prey as large as deer and water buffalo. They are ancient, formidable reptiles that have survived in isolation for millions of years.
