It ranges from the Aldabras to the Solomon Islands, Guam, and Fiji. It is threatened by invasive animals, by humans as a food and medicinal source, and habitat destruction. This species should probably be kept singly, as aggressiveness has been reported. The crabs will burrow into the sand. A large bowl of fresh water is necessary.
High humidity is recommended.
Cuttlebone was provided as a calcium supplement. Mites were cleaned off with a water sprayer to remove any chance of damaging the crab's respiratory system. Stress appears to be a big problem with these invertebrates, and much care should be taken to keep traffic low around their cages. Moulting can also be difficult for these animals. Robertson, M. 1991.
