Coconut crabs live alone in burrows and rock crevices, depending on the local terrain. They dig their own burrows in sand or loose soil. During the day, the animal stays hidden to reduce water loss from heat. The coconut crabs' burrows contain very fine yet strong fibres of the coconut husk which the animal uses as bedding. [43]
Female coenobitids return to the sea to hatch their eggs and their larvae develop through planktonic zoeal stages to a megalopa, in a similar way as the marine hermit crabs. Just like these species, after settlement, terrestrial hermit crabs megalopae recognize and co-opt gastropods shells, before migrating into the land and molting to the ...
[11] Both corals and long-lived animals such as coconut crabs should be vulnerable to radiation-induced cancers, [56] and understanding how they have thrived might lead to discoveries about preserving DNA. Pambuli notes that the Bikini Atoll is "an ironic setting for research that might help people live longer".
The coconut crab, Birgus latro, is a species of terrestrial hermit crab, also known as the "robber crab" or "palm thief". It is the largest land-living arthropod in the world, and is probably at the upper size limit of terrestrial animals with exoskeletons in today's atmosphere at a weight of up to 4.1 kg (9.0 lb).

Turns out the crabs swarmed the pig’s body, removed most of its flesh, and moved some of the bones as far as 60 feet away. “This tells us crabs drag bones,” TIGHAR’s Tom King told National ...
The adults can grow up to .5 pounds (230 g). They can live 12–70 years and are known to grow to the size of a coconut. During the beginning of the crab's juvenile stage the middle of its carapace possesses a long reddish pigment area as does each side wall of the carapace.
Billions of snow crabs have disappeared from the ocean around Alaska in recent years, and scientists now say they know why: Warmer ocean temperatures likely caused them to starve to death.
