A Red Hermit Crab (Petrochirus diogenes) peers out of a Queen Conch (Strombus gigas) submerged 48 feet below Horseshoe North, Turniffe Islands, Belize, Central America. The Red Hermit Crab is the largest hermit crab species found from North Carolina to Brazil. Also known as the Giant Hermit, it tends to preferentially inhabit discarded shells of the Queen Conch as shown here. The Queen Conch shell attains length of over 12 inches, feeding almost exclusively on algae. Its meat is utilized extensively as food and fish bait throughout Puerto Rico and the West Indies. The Red Hermit Crab generally inhabits sand bottoms and seagrass flats to a depth of over 300 feet. While many hermit crab species have their left claw substantially larger than the right, the Giant Hermit possesses a right claw that is slightly more massive than the left. Fertilized eggs are carried attached to the underbody of the female crab before hatching into larva which float has plankton when young. The Giant Hermit derives its Latin genus name from its hard and stony fingertips (petro = stony, chirus = finger).
