Johngarthia Lagostoma
''Johngarthia lagostoma'' is a species of terrestrial crab that lives on Ascension Island and three other islands in the South Atlantic. It grows to a carapace width of on Ascension Island, where it is the largest native land animal. It exists in two distinct colour morphs, one yellow and one purple, with few intermediates. The yellow morph dominates on Ascension Island, while the purple morph is more frequent on Rocas Atoll. The species differs from other '' Johngarthia'' species by the form of the third maxilliped. ''Johngarthia lagostoma'' lives in burrows among vegetation, at altitudes of up to , emerging at night to feed on plant matter and occasionally on animals. From January to March there is an annual migration to the sea to release the planktonic larvae. The species was first described (as ''Gecarcinus lagostoma'') by Henri Milne-Edwards in 1837 from material sent to him by the naturalists Jean René Constant Quoy and Joseph Paul Gaimard, collected by the Fren ...

Johngarthia Planata
''Johngarthia planata'', sometimes known as the Clipperton crab, is a bright orange species of land crab that lives on Clipperton Island in the eastern Pacific; on Malpelo Island, west of Colombia; and on Socorro Island in the Revillagigedo Islands off Mexico, 900 km north of Clipperton. It is omnivorous and feeds on seaweed (algae), vegetation and sometimes carrion. The introduction of pigs on Clipperton Island by guano miners in the 1890s reduced the crab population: this in turn allowed grassland to gradually cover about 80 percent of the land surface. The elimination of these pigs in 1958 — as the result of a personal project by Kenneth E. Stager — has caused most of this vegetation to disappear, resulting in the return of millions of ''J. planata''.

Ascension Island
Ascension Island is an isolated volcanic island, 7°56′ south of the Equator in the South Atlantic Ocean. It is about from the coast of Africa and from the coast of South America. It is governed as part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, of which the main island, Saint Helena, is around to the southeast. The territory also includes the sparsely populated Tristan da Cunha archipelago, to the south, about halfway to the Antarctic Circle. Named after the day of its recorded discovery, Ascension of Jesus, Ascension Island was an important safe haven as a coaling station to mariners and a refueling stop for commercial airliners back in the days of international air travel by flying boats. Ascension Island was garrisoned by the British Admiralty from 22 October 1815 to 1922. During World War II, it was an important naval and air station, especially providing antisubmarine warfare bases in the Battle of the Atlantic.Victory at ...

Gecarcinus Johngarthia Planatus - Crabe De Clipperton Wiki14
''Gecarcinus'' is the type genus of the land crab family Gecarcinidae. They are found in warmer coastal regions of the Americas, including islands in the Caribbean. Four species from oceanic islands were formerly included in ''Gecarcinus'' as the subgenus ''Johngarthia'', but are now treated as a separate genus, ''Johngarthia''. While all members of this genus are largely terrestrial, they have to return to the ocean to breed (the larvae A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The ... are released into the sea). They are often colourful, with reddish, orange, purple, yellowish, whitish, or blackish being the dominating hues.

Gecarcinidae
The Gecarcinidae, the land crabs, are a family of true crabs that are adapted for terrestrial existence. Similar to all other crabs, land crabs possess a series of gills. In addition, the part of the carapace covering the gills is inflated and equipped with blood vessels. These organs extract oxygen from the air, analogous to the vertebrate lungs. Adult land crabs are terrestrial, but visit the sea periodically, where they breed and their larvae develop. Land crabs are tropical omnivores which sometimes cause considerable damage to crops. Most land crabs have one of their claws larger than the other. The family contains these genera: * ''Cardisoma'' * '' Discoplax'' * '' Epigrapsus'' * '' Gecarcinus'' * '' Gecarcoidea'' * '' Johngarthia'' * ''Tuerkayana'' See also *Sesarmidae, another family of terrestrial crabs *Coenobitidae The Coenobitidae are the family of terrestrial hermit crabs, widely known for their land-living habits as adults.

Cocos Island
Cocos Island ( es, Isla del Coco) is an island in the Pacific Ocean administered by Costa Rica, approximately southwest of the Costa Rican mainland. It constitutes the 11th of the 13 districts of Puntarenas Canton of the Province of Puntarenas. With an area of approximately , the island is more or less rectangular in shape. It is the southernmost point of geopolitical North America if non-continental islands are included. The entirety of Cocos Island has been designated a Costa Rican National Park since 1978, and has no permanent inhabitants other than Costa Rican park rangers. Surrounded by deep waters with counter-currents, Cocos Island is admired by scuba divers for its populations of hammerhead sharks, rays, dolphins and other large marine species.

Fernando De Noronha
Fernando de Noronha () is an archipelago in the Atlantic Ocean, part of the State of Pernambuco, Brazil, and located off the Brazilian coast. It consists of 21 islands and islets, extending over an area of . Only the eponymous main island is inhabited; it has an area of and a population estimated at 3,101 in 2020.
