Batwing Coral CrabCarpilius corallinus
Also known as the Red Coral Crab, Coral Crab or Queen Crab. they inhabit shallow reefs and hide in recesses during the day. I was fortunate enough to see these two specimens during the day. Both were at a depth of about 6 feet. They generally only come out at night to forage for food. They are a True Crab and belong to the Mud Crab Family. Carapaces: rounded about four inches in diameter.
