[25] The empty egg cases remain on the female's body after the larvae have been released, and the female eats the egg cases within a few days. [36] During a tagging experiment, one coconut crab was observed killing and eating a Polynesian rat (Rattus exulans). [28] The western limit of the range of B. latro is Zanzibar, off the coast of Tanzania,[29] while the tropics of Cancer and Capricorn mark the northern and southern limits, respectively, with very few population in the subtropics, such as the Ryukyu Islands. When they outgrow their shells, they develop a hardened abdomen. The diet of coconut crabs consists primarily of fleshy fruits (particularly Ochrosia ackeringae, Arenga listeri, Pandanus elatus, P. christmatensis); nuts (Aleurites moluccanus), drupes (Cocos nucifera) and seeds (Annona reticulata); and the pith of fallen trees. [31] Other Indian Ocean populations exist on the Seychelles, including Aldabra and Cosmoledo,[32] but the coconut crab is extinct on the central islands. Similarly, floating coconuts can be a very significant part of the crab's dispersal options. . ] As with all hermit crabs, they change their shells as they grow. In fact, this species of arthropod is known to feed on coconuts, which it opens with its pincers. They remain inside their burrows during the day to reduce water loss from their bodies. Scientist Mark Laidre described their attack strategy in horrific detail.It was on an island where the birds had learned to live in fear. [30], Christmas Island in the Indian Ocean has the largest and densest population of coconut crabs in the world,[18] although it is outnumbered there by more than 50 times by the Christmas Island red crab, Gecarcoidea natalis. [27] At that time, they sometimes visit dry land.

On many occasions human beings complain about this situation, but we must remember that we are the ones who destroy or pollute their habitat.In general, coconut crabs like to live among the cracks of the rocks, and in burrows made in the sand, although these preferences change in some occasions depending on the places available. Coconut crab considered as delicacy by human so it is less common in areas inhabited by humans. Takutea, Mauke, Atiu and Palmerston are also worth highlighting. The larvae pass through three to five zoea stages before moulting into the postlarval glaucothoe stage; this process takes from 25 to 33 days. [58] In Japan (where the species lives on some of the country's southerly island chains), the species is typically referred to as Yashigani (ヤシガニ),[59] meaning 'palm crab'. As most crabs live in the water, they have specialised organs called aesthetascs on their antennae to determine both the concentration and the direction of a smell. They begin life as microscopic larvae in the ocean. Common names for the species include coconut crab, robber crab, and palm thief,[1] which mirrors the animal's name in other European languages (e.g. The bag limit is five coconut crabs on any given day, and 15 across the whole season. [23] The extrusion of eggs occurs on land in crevices or burrows near the shore. A large population of these crabs can be found in the Cook islands, an archipelago located between Hawaii and New Zealand. [1], Conservation management strategies have been put in place in some regions, such as minimum legal size limit restrictions in Guam and Vanuatu, and a ban on the capture of egg-bearing females in Guam and the Federated States of Micronesia. We will explain where do coconut crabs live and some more fun facts about them. The species is popularly associated with the coconut palm, yet coconuts are not a significant part of its diet. Coconut crabs play a key role in TIGHAR’s hypothesis about what happened to Amelia Earhart after she and navigator Fred Noonan disappeared on July 2, … [18] While insects and the coconut crab originate from different paths, the same need to detect smells in the air led to the development of remarkably similar organs. On some islands, they can be found up to six kilometres from the shore. Coconut Crabs color varies from red to blue. Find out Everything about this Hybrid, The 10 Most Solitary Animals in the World. [35] In the 1980s, Holger Rumpf was able to confirm Streets' report, observing and studying how they open coconuts in the wild. This organ is expanded laterally and is evaginated to increase the surface area;[11] located in the cephalothorax, it is optimally placed to reduce both the blood/gas diffusion distance and the return distance of oxygenated blood to the pericardium. In the 3–4 weeks that the larvae remain at sea, their chances of reaching another suitable location is enhanced if a floating life support system avails itself to them. The coconut crab is the only species of the genus Birgus, and is related to the terrestrial hermit crabs of the genus Coenobita. The strongest: the coconut crab The coconut crab is also known as the robber crab or … [48], The pincers of the coconut crab are powerful enough to cause noticeable pain to a human; furthermore, the coconut crab often keeps its hold for extended periods of time. Adult coconut crabs are about 1 metre (40 inches) from leg tip to leg tip and weigh about 4.5 kg (10 pounds). [18] The process of smelling works very differently depending on whether the smelled molecules are hydrophilic molecules in water or hydrophobic molecules in air. Level Contributor . [15] The branchiostegal lung contains a tissue similar to that found in gills, but suited to the absorption of oxygen from air, rather than water. [53], In Tuvalu, coconut crabs live on the motu (islets) in the Funafuti Conservation Area, a marine conservation area covering 33 km2 (12.74 mi2mi) of reef, lagoon and motu on the western side of Funafuti atoll. These animals mostly inhabit the Indian Ocean a… [11] The fourth pair of legs is smaller with tweezer-like chelae at the end, allowing young coconut crabs to grip the inside of a shell or coconut husk to carry for protection; adults use this pair for walking and climbing. Researchers such as marine biologist Shin-ichiro Oka monitor the coconut crabs in Okinawa. [6], The body of the coconut crab is, like that of all decapods, divided into a front section (cephalothorax), which has 10 legs, and an abdomen. They also populate Suwarrow, an island among 22 others, and Mangaia, the southernmost of these islands. They dig these holes in loose soil or sand. They live almost exclusively on land, returning to the sea only to release their eggs; on Christmas Island, for instance, B. latro is abundant 6 km (3.7 mi) from the sea. [35] The Gambier Islands mark the species' eastern limit. [4], B. latro is the largest terrestrial arthropod, and indeed terrestrial invertebrate, in the world;[5][6] reports about its size vary, but most sources give a body length up to 40 cm (16 in),[7] a weight up to 4.1 kg (9.0 lb), and a leg span more than 0.91 m (3.0 ft),[8] with males generally being larger than females. [10] The hardened abdomen protects the coconut crab and reduces water loss on land, but must be moulted periodically. It is closely related to the hermit crab and king crab. Amelia Earhart was a pioneer of American aviation. In fact, this species of … Among terrestrial arthropods, the phylum that includes crustaceans, spiders and insects, coconut crabs are the largest on the planet. As sexual maturity doesn’t occur until 5 years old, predation of larger crabs by animals or humans can lead to a population being unable to recover. The coconut crab, known scientifically as Birgus latro, does not take its name from it appearance. [39] In 2016, a large coconut crab was observed climbing a tree to disable and consume a red-footed booby on the Chagos Archipelago. Sexual maturity is reached after about 5 years, and the total lifespan may be over 60 years. 4,829 posts. [11][38] They have been observed to prey upon crabs such as Gecarcoidea natalis and Discoplax hirtipes, as well as scavenge on the carcasses of other coconut crabs. They stayed up at the tops of the trees, never daring to touch down onto the ground below where they knew the powerful pincers of the coconut crabs were waiting to crush their bones. It is found on islands across the Indian Ocean, and parts of the Pacific Ocean as far east as the Gambier Islands and Pitcairn Islands, similar to the distribution of the coconut palm; it has been extirpated from most areas with a significant human population, including mainland Australia and Madagascar. Although you may not believe it, crabs can even use abandoned houses to inhabit them. In areas with a large coconut crab population, some may come out during the day, perhaps to gain an advantage in the search for food. Adults moult annually, and dig a burrow up to 1 m (3 ft 3 in) long in which to hide while vulnerable. Other times, they emerge if it is moist or raining, since these conditions allow them to breathe more easily.

I lived on Saipan for about 9 months in the early 90's, and have seen them a number of times crossing the roads on the remote part of the island. Climbing is an immediate escape route (if too far from the burrow) to avoid predation (when young) by large sea birds, or cannibalism (at any age) by bigger, older crabs. Coconut crabs don’t usually bother people, but they will if provoked. Not being constrained by the physical confines of living in a shell allows this species to grow much larger than other hermit crabs in the family Coenobitidae. Mating occurs on dry land, but the females return to the edge of the sea to release their fertilized eggs, and then retreat back up the beach. Other crabs have adapted to live holes that they dig on land land crabs and inhabit the forest floor or forage in trees eg the coconut crab. They have to live near salt water and are especially vulnerable to loss of habitat due to coastal development. All are decapod crustaceans (order Decapoda, class Crustacea). [11], Coconut crabs live in the Indian Ocean and the central Pacific Ocean, with a distribution that closely matches that of the coconut palm. Afterwards, it turns around and uses the smaller pincers on its other legs to pull out the white flesh of the coconut. They dig their own burrows in sand or loose soil.
