Christmaplacidae is a family of crabs in the superfamily Pseudozioidea containing the species Christmaplax mirabilis from Christmas Island, Australia, and Harryplax severus from Guam. [1] [2]
Christmas Island, officially known as the Territory of Christmas Island, is an Australian external territory comprising the island of the same name. It is located in the Indian Ocean, around 350 kilometres (220 mi) south of Java and Sumatra and around 1,550 km (960 mi) north-west of the closest point on the Australian mainland. It lies 2,600 km (1,600 mi) northwest of Perth and 1,327 km (825 mi) south of Singapore. It has an area of 135 square kilometres (52 sq mi).
The yellow crazy ant(Anoplolepis gracilipes) is a species of ant, originally from Southeast Asia, that has been accidentally introduced to numerous places in the world's tropics.
The Christmas Island red crab is a species of land crab that is endemic to Christmas Island and Cocos (Keeling) Islands in the Indian Ocean. Although restricted to a relatively small area, an estimated 43.7 million adult red crabs once lived on Christmas Island alone, but the accidental introduction of the yellow crazy ant is believed to have killed about 10–15 million of these in recent years. Christmas Island red crabs make an annual mass migration to the sea to lay their eggs in the ocean. Although its population is under great assault by the ants, as of 2020 the red crab had not been assessed by the International Union for Conservation of Nature (IUCN) and it was not listed on their Red List.
Hymenosomatidae is a family of crabs with some 110 described species in nearly 20 genera. The following genera are placed in the Hymenosomatidae:
Tuerkayana hirtipes is a species of terrestrial crab.
Discoplax is a genus of terrestrial crabs. It is very closely related to the genus Cardisoma.
The Christmas Island shrew, also known as the Christmas Island musk-shrew is an extremely rare or possibly extinct shrew from Christmas Island. It was variously placed as subspecies of the Asian gray shrew or the Southeast Asian shrew, but morphological differences and the large distance between the species indicate that it is an entirely distinct species.
Potamonautidae is a family of freshwater crabs endemic to Africa, including the islands of Madagascar, the Seychelles, Zanzibar, Mafia, Pemba, Bioko, São Tomé, Príncipe and Sherbro Island. It comprises 18 extant genera and 138 extant species. Fossil remains dating from the Late Miocene period have been attributed to the family Potamonautidae.
Geosesarma is genus of small freshwater or terrestrial crabs, typically less than 10 mm (0.4 in) across the carapace. They live and reproduce on land with the larval stages inside the egg. They are found from India, through Southeast Asia, to the Solomon Islands and Hawaii.
Christmas Island National Park is a national park occupying most of Christmas Island, an Australian territory in the Indian Ocean southwest of Indonesia. The park is home to many species of animal and plant life, including the eponymous red crab, whose annual migration sees around 100 million crabs move to the sea to spawn. Christmas Island is the only nesting place for the endangered Abbott's booby and critically endangered Christmas Island frigatebird, and the wide range of other endemic species makes the island of significant interest to the scientific community.
Hainanpotamon vietnamicum is a species of crab. Originally described as a species of Geothelphusa, it is now treated as part of the genus Hainanpotamon, although it has also been suggested as a member of Tiwaripotamon. It is only known from a single locality in Cúc Phương National Park, Ninh Bình Province, Vietnam.
Pseudozioidea is a superfamily of crabs, formerly treated in the Eriphioidea, Carpilioidea, Xanthoidea, Pilumnoidea and Goneplacoidea. A number of fossils from the Eocene onwards are known from the family Pseudoziidae. Eleven genera are recognised in three families:
Johora singaporensis, the Singapore stream crab or Singapore freshwater crab, is a critically endangered species of freshwater crab endemic to Singapore. It grows to a size of 30 millimetres (1.2 in) wide.
Karstarma is a genus of karst-dwelling crabs formerly included in Sesarmoides.
Liagore is a genus of crabs in the family Xanthidae, native to Australia, containing the following species:
Hainanpotamon is a genus of freshwater crabs, containing the following species:
Moguai is a genus of crabs. The name comes from the Chinese pinyin, which literally means "devil". It contains three species:
Atergatis floridus, the floral egg crab, green egg crab or shawl crab, is a species of tropical Indo-Pacific crab from the family Xanthidae. The meat of this crab is toxic, even if cooked, and consumption often results in death.
Christmaplax mirabilis is a species of crab native to Christmas Island, Australia. It is the only known species in the genus Christmaplax.
