MARINE OTTER:  Also known as sea otters, marine otters can reach lengths up to 4 feet.  Mollusks and sea urchins make up the typical diet for an adult sea otter.  After catching their hard shelled meals, sea otters smash the tough outer shells of their prey with rocks and eat the soft insides.  Sea otters are the only marine animals that don't have an insulating layer of blubber.  To make up for this, sea otters must clean themselves constantly and keep an insulation layer of air under their fur.  Marine otters are classified as moderately endangered due to a decline in their area of occupancy and high levels exploitation.
 
 

    LEATHERBACK TURTLE:  The leatherback turtle is the largest living turtle.  Leatherbacks can reach a length of 8 feet and weigh close to 1,907 pounds.  They can be found farther north and south than any other type of sea turtle.  They are able to survive in these below freezing waters by generating their own heat.  They do this by having a large body mass and maintaining muscular activity.  Leatherbacks have a hard, leathery outer shell; which is usually black or blue-black.  The greatest threat to leatherbacks is the illegal collecting of their eggs.

    HAWAIIAN GREEN TURTLE:  The green turtle is the fastest swimming turtle.  It can reach speeds up to 20 mph.  The green turtle can be found in most warm seas.  Adult green turtles can reach a length of over three feet and can weigh over 400 pounds.  Green turtles can be distinguished from other sea turtles because they have a pair of bony plates between their eyes, and they have a very smooth shell.  The green turtle is listed as endangered due to over hunting.  They are prized by turtle hunters for their veal like meat, and for their eggs.
