Also known as Ghost Crab, Horned Ghost Crab, Sand Crab, Shore Crab.
Found close to their burrows on gravel and sandy areas of intertidal beaches.
These crabs often use their claws to scrape flies from the underside of leaves.
They feed on small animals, carrion, detritus and eggs.
Width - 5cm
Depth - High tide area
Widespread Indian Ocean
Males have a single enlarged claw, while females have two small feeding claws. They feed by scraping the surface sediment up in their small claws, transferring it to the mouth where the complex mouth parts sift out the organic matter. They then spit out a small pellet of cleaned sand. These feeling pellets cover the mudflat by the end of the low tide period. Because males have only one small, feeding claw, they feed at half the rate of the females. They therefore have to spend about double the time feeding.
Males also use their large claw for fighting as well as mating by waving it around.
Like all crabs, these crabs shed their shells as they grow. If they have lost legs or claws during their present growth cycle a new one will be present when they moult. If the large fiddle claw is lost, males will develop one on the opposite side after their next moult. Newly moulted crabs are very vulnerable because of their soft shells. They are reclusive and hide until the new shell hardens. Ref: https://en.wikipedia.org/wiki/Ocypode_brevicornis
