Can disguise as a coral. Stay still to turn invisible and create a lure. If the lure is eaten, damage is doubled for one attack.How the crabs produced the clicking sounds had been a mystery up until now.
Not only that, researchers also found that crabs could produce multiple sounds that varied in frequency and intervals when the vibration speed changed. They also use it quite a bit during sex. Research on mating coconut crabs showed that they create noises before, during, and after their mating sessions. Furthermore, the noises that the crabs produce sounds different at each stage of their mating.
While the aquatic crayfish Procambarus clarkii is known to create sounds using a similar structure, coconut crabs are the only land crustaceans known to do this, the authors reported. Coconut crabs Birgus latro are the largest land crabs on Earth.
They weigh up to nine pounds with a leg span of three feet. Interestingly, unlike other crab species, these giant beach-dwellers are unable to swimwhich prevents them from island-hopping around the Indian Ocean. So some islands naturally harbor higher populations of coconut crabs than others. As their name suggests, their main food source is coconuts, which the crabs can easily cut into using their thick, sharp claws.
Being equipped with such sturdy tools, coconut crabs have been known to hunt meat, too, such as seabirds. In some cases, they even cannibalize the corpses of their own. Despite their ferocious appearance, coconut crabs rarely hurt humans. Coconut crabs more should fear humans. Next, read how mutant crayfish in Europe are cloning themselves like cray cray and learn the devastating fact of scientists finding particles from the atomic bomb tests inside creatures living 36, feet below the sea.

Take a look at their bigger cousin at top, the giant coconut crab Birgus latrothe largest land-dwelling crustacean in the world. This highly apomorphic hermit crab is known for its ability to crack coconuts with its strong pincers in order to eat the contents.
If you have any in your neighborhood, you usually know it. On the news front, in Augustthe current US administration proposed a ban on commercial fishing and mineral exploration on and around three large Pacific island chains.
The Northern Mariana Islands, the Line Islands, and American Samoa are likely to be deemed protected areas, preserving a remote swath of biodiversity that might otherwise be destroyed. Animals like migratory sea birds, sea turtles, and the huge coconut crabs will benefit from the designation, which comes just two years after similar protections were placed on the Northwestern Hawaiian Islands. The Papahanaumokuakea Marine National Monument was created as a national monument, barring fishing, oil and gas extraction and tourism from its waters and coral reefs.
The area is the single largest conservation area on the planet. The coconut crab is also called the robber crab or palm thief, because some coconut crabs are rumored to steal shiny items such as pots and silverware from houses and tents. The diet of coconut crabs consists primarily of fruit, including coconuts Cocos nucifera and figs Ficus species.Comedians Talk to Pet Expert Mister Crabs & his Giant Coconut Crab/Robber Crab
However, they will eat nearly anything organic, including leaves, rotten fruit, tortoise eggs, dead animals, and the shells of other animals, which are believed to provide calcium.
They may also eat live animals that are too slow to escape, such as freshly hatched sea turtles. During a tagging experiment, one coconut crab was observed catching and eating a Polynesian Rat Rattus exulans. Coconut crabs often try to steal food from each other and will pull their food into their burrows to be safe while eating. No reports of them taking small children have been encountered, but coconut crabs are kept as pets in Japan.
If a human is caught with a pincer, reportedly the crabs do not release their grip easily.
However, some Pacific islanders have developed a special technique in which the underside of the crab is tickled so the crab will let go of its human victim. The coconut crab climbs trees to eat coconuts or fruit, to escape the heat or to escape predators. Coconut crabs cut holes into coconuts with their strong claws and eat the contents; this behavior is unique in the animal kingdom. Also, unique to this species among crabs, they smell with a nose. It is the only species of the genus Birgus.

It is closely related to the hermit crab and king crab. All are decapod crustaceans order Decapodaclass Crustacea. Adult coconut crabs are about 1 metre 40 inches from leg tip to leg tip and weigh about 4. The full-grown adult ranges in colouring from light violet to brown and deep purple.
Young adults are brown, with black stripes on their legs. Coconut crabs are generalist scavengers that feed on fallen fruitcarrion, and to ingest calcium the shells of other crabs. The coconut crab is known for its ability to use its massive pincers chelae to crack open coconuts.
The largest coconut crabs can exert a force of 3, newtons about pound-force with their pincers. The female releases her ripe eggs in the sea, and they immediately hatch as microscopic swimming zoeas. This first larval stage, which lives in the water, feeds on small organisms. After 20 to 30 days the zoea develops into a glaucothoe, the intermediate stage, and leaves the water to live in a seashell for three or four weeks.
It then discards the shell, buries itself in moist sand, and transforms into a small adult. Most of the daylight hours are passed in burrows up to about 0.

But when these crabs aren't devouring seabirds, they're chatting to each other in vibrating clicks, and scientists recently discovered that the crabs' weird clicking calls are unexpectedly diverse. In fact, their crabby chatter contains a range of signals that could represent complex levels of communication for a crab, at leastaccording to a new study. Related: Photos: Ancient crab is the strangest you've ever seen. Weighing up to 9 lbs. These cousins of hermit crabs once inhabited islands across the Indo-Pacific area, but people harvested coconut crabs to extinction in many of their former habitats, scientists wrote in the study, published in the December issue of the journal Zoology.
Previously, the researchers found that the crabs produced "tapping-like sounds," but they were unsure how and why the animals made those noises. For the new study, the scientists captured X-ray movies of the clicking crabs to uncover the source of their acoustic prowess; they also recorded digital audio of the crabs during interactions between males and females, to see if the clicking was linked to mating behavior. In experiments, male and female coconut crabs clicked before, during and after mating — and the sounds that they made were different at each stage.
X-rays revealed that the crabs were communicating by vibrating thin appendages known as scaphognathites, which draw air into the crabs' lungs. When the structures vibrate, they flutter against hard plates in the crabs' gill channels to generate a tapping sound.
By changing the structure's vibration speed, the crabs could produce multiple sounds that varied in frequency and intervals, according to the study. The only other crustacean that produces sound with its scaphognathites is the aquatic crayfish Procambarus clarkiiand coconut crabs are now the only land crustaceans known to exhibit this behavior, the researchers reported.
Long before coconut crabs caught scientists' attention with their clicking, they were renowned for their girth. More than a decade ago, the internet audience was transfixed and terrified by a much-circulated photo of a truly monstrous coconut crab that appeared to be the size of a trash can. However, the scale in the photo was misleading, and the crab — though large — was probably not quite as big as it looked, biologist Michael Bok wrote in January on his blog Arthropoda.
An outdoor trash can such as the one in the crab photo typically measures about 4. But the bin in the photo is likely much smaller than average, making the crab look bigger by comparison, Bok explained. Even if coconut crabs aren't as long as a trash can, they're still formidable creatures with a pinch more powerful than that of any other crustacean — and even stronger than most animals' bites, Live Science previously reported.
In fact, researchers documented a coconut crab snatching a large seabird from its nest, breaking its wings and ripping it to pieces, Science Alert reported in Gruesome footage captured by Mark Laidre, an assistant professor in the Department of Biological Sciences at Dartmouth College in New Hampshire, showed a stealthy crab using its pincers to cripple and subdue a red-footed booby Sula sula in the Chagos Archipelago in the Indian Ocean.
Though the experiments in the new study only recorded interactions between amorous male and female crabs, their clicking conversation could extend beyond mating encounters, the scientists wrote. However, more tests will be necessary under a variety of conditions in order to decode the extent of coconut crabs' "language," according to the study.

As such, the new study aimed to answer the question by capturing X-ray footage of the clicking crabs to uncover where the sounds come from. The scientists then found that male and female crabs clicked before, during and after mating, with the sounds at every stage different from the last. Furthermore, the study also found that crabs are able to make the clicking sounds by vibrating thin appendages known as scaphognathites, which draw air into the crabs' lungs.
When these structures vibrate, they flutter against hard plates in the crabs' gill channels that then generate a tapping sound. The crabs are then able to make different clicking sounds simply by changing the vibration speed of the structure. A coconut crab. Photo by Pixabay CC0.
