A Hawaiian Green Sea Turtle cruises the sea floor off the Oahu shoreline looking for a bite to eat. Adult green sea turtles like this one are herbivores, eating mainly algae and different seagrasses. Sea turtles can spend twenty minutes or more underwater while swimming and eating, and more than a couple hours underwater while sleeping.
