Mangrove Horseshoe Crab (Carcinoscorpius rotundicauda)

…is a species of horseshoe crab found throughout Southeast Asia and India and is the only member of the genus Carcinoscorpius. Like other horseshoe crabs the mangrove horseshoe crab is primarily nocturnal and feeds on benthic invertebrates like insect larvae, worms, and crustaceans, it grinds these food items up with its bristly legs and moves them into its chelicerae to be ingested. Like their Atlantic cousins mangrove horseshoe crabs will congregate in the shallows during the spring for mating (although they don't do it in the same force.)
