jo, men så kan den vel også teknisk set knuse en kokosnød...

Transitfar skrev:Lidt fra den danske Wikipedia:
"Palmetyven (Birgus latro) er en stor eremitkrebs, som findes i tropiske egne af det Indiske ocean og Stillehavet. Den lever enten på øer eller i mangroveskove. Den er 60 cm. lang, har en benvidde på 90 cm. og vejer hele 3 kg. Dens store størrelse gør, at den i modsætning til andre eremitkrebs ikke skjuler sig i ting som f.eks. konkylier."
Og:
"...Derfor klatrer simpelthen op i en kokospalme, løsner en kokosnød så den falder til jorden og bliver knust"

Har du nogen sinde set en kokosnød der kommer direkte fra et palmetræ ??
de er dækket af et beskyttende "frugtkøds" lag der er op til flere cm tyk og som fra naturens side er designet til blandt andet at beskytte nøden når den falder ned fra træet ... derudover så står de fleste palmer enten ved sandstrand eller tropisk skovbund hvoraf hverken er speciel hård for en kokosnød ...

nu har jeg selv prøvet at splitte en kokosnød som jeg hentede fra en palme på Borneo ( hvis man er dykker og kommer på de kanter så skal man tage en tur til Sipidan ) og bare det at komme ind til selve nøden kræver lidt mere end et fald fra 6m .. desuden så var denne nød ikke helt moden så det man herhjemme kender som skalden på nøden var ikke specielt tyk men omkring 3mm og en anelse elastisk samt selve frugtkødet inde i nøden (det hvide) var kun blevet en 3-4mm tykt og var ret svampet .. men nu var det ikke for kødets skyld men for at drikke saften jeg havde hentet nøden .. men af en eller anden grund havde jeg ikke rigtigt tænkt over at saften fra sådanne en nød der havde hængt og bagt i sydhavssolen var alt andet end forfriskende kold

Diet

The diet of coconut crabs consists primarily of fruit, including coconuts (Cocos nucifera) and figs (Ficus species). 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).[8] Coconut crabs often try to steal food from each other and will pull their food into their burrows to be safe while eating.

The coconut crab climbs trees to eat coconuts or fruit, to escape the heat or to escape predators. It is a common perception that the coconut crab cuts the coconuts from the tree to eat them on the ground (hence the German name Palmendieb, which literally means "palm thief," and the Dutch Klapperdief). Coconut crabs cut holes into coconuts with their strong claws and eat the contents; this behavior is unique in the animal kingdom.
Thomas Hale Streets discussed the behavior in 1877 - while at the same time doubting that the crab would climb trees to get at the nuts.[9] And in the 1980s Holger Rumpf was able to confirm Streets' report, observing and studying how the crabs open coconuts in the wild. The animal has developed a special technique to do so: if the coconut is still covered with husk, it will use its claws to rip off strips, always starting from the side with the three germination pores, the group of three small circles found on the outside of the coconut. Once the pores are visible, the crab will bang its pincers on one of them until they break. Afterwards, it will turn around and use the smaller pincers on its other legs to pull out the white flesh of the coconut. Using their strong claws, larger individuals can even break the hard coconut into smaller pieces for easier consumption.

....They are protected on these islands from being hunted and/or eaten, with fines of up to 1500 British pounds (roughly $3000 USD) per crab consumed....

...The coconut crab is eaten by the Pacific islanders, and is considered a delicacy and an aphrodisiac, with a taste similar to lobster and crab meat. The most prized parts are the eggs inside the female coconut crab and the fat in the abdomen. Coconut crabs can be cooked in a similar way to lobsters, by boiling or steaming. Different islands also have a variety of recipes, as for example coconut crab cooked in coconut milk. While the coconut crab itself is not innately poisonous, it may become so depending on its diet, and cases of coconut crab poisoning have occurred. It is believed that the poison comes from plant toxins, which would explain why some animals are poisonous and others not. Reputedly[citation needed] this poison is considered an aphrodisiac, similar to the highly poisonous pufferfish eaten in Japan. However, coconut crabs are not a commercial product and are usually not sold....
