Marine Reptiles
Reptiles are relatively uncommon residents of the marine environment. Of the small group of reptiles that inhabit the sea, perhaps the most easily recognized are the sea turtles. There are only seven species of sea turtles worldwide, and all but one are endangered. Sea turtles, such as the loggerhead, hawksbill, green, and olive ridley, are relatively common throughout the waters of Hawaiian Islands Humpback Whale National Marine Sanctuary.
