Johngarthia Lagostoma YELLOW Species Synonyms Gecarcinus Lagostoma H. Milne Edwards, 1837 Johngarthia Lagostoma is a kind of terrestrial crabs of the Gecarcinidae family who lives on the island of Ascension and three other islands of the South Atlantic. Adult, he reached a shell width of around 110 mm On the island of Ascension, where it is the largest native terrestrial animal. There are in two distinct forms of color, one yellow, the other violet, with some intermediaries. The yellow color dominates on the island of Ascension, while purple is more frequent on the atoll das rocas. The species differs from the other species of Johngarthia by the form of its third maxillip\u00e8de.Johngarthia Lagostoma lives in burrows in vegetation areas, to altitudes up to 400 m . He leaves the night to feed on vegetable matter and sometimes on animals. From January to March, individuals begin a migration to the sea to release their planktonic larvae. The species was described for the first (like Gecarcinus lagostoma) by Henri Milne-Edwards in 1837 from sample sent and collected by the naturalists Jean Ren\u00e9 Constant quoy and Joseph Paul Gaimard, collected by the French ship the astrolabe.   This species is found on the islands of Ascension, Trindade, Fernando de Noronha and the Atoll Das Rocas [ first ] . On the island of Ascension, the distribution area of \u200b\u200bJ. Lagostoma outside the breeding season is limited to the slopes of the green mountain, where there is humidity and vegetation is sufficient, the rest of The island constituting too arid habitat to survive. All lands above 400 meters is a suitable habitat for crabs, just like a large part of the earth above 200 m . They are sometimes at lower altitudes, including in the well-watered gardens of Georgetown, and near a colony of fuliginous sterne in the southwest of the island (known as Wideawake Fairs). On the island of Trindade, J. Lagostoma is abundant where the vegetation is present, including the highest parts of the island.The geographic distribution of J. Lagostoma through a small number of islands in the South Atlantic Ocean is difficult to explain by the planktonic dispersion. His closest relatives are the other species of Johngarthia, two of which (J. Planata and J. Malpilensis) who live in the Pacific Ocean islands off Central America, and a J. Weileri found in The Islands of the Gulf of Guinea. Some naturalists have suggested the existence of ancient islands, now overwhelmed, which could have acted as a “springboard” for the colonization of the Ascension Island, the isolation of the island of the ascension of all Another land mass to colonization by two difficult larvae or adults.  Johngarthia Lagostoma violet  Johngarthia Lagostoma YELLOW Mature specimens have a shell width of 70-110 mm On the island of Ascension, the individuals of the Das Rocas Atol are a little smaller. In the Gecarcinidae family, species are normally distinguished by the form of their first Pleopod (gonopod), which is used by males during coupling, but there is no difference in the Gonopods of J. Planata and J . Lagostoma. J. Lagostoma differs from other species of the genus by the shape of his third Maxillip\u00e8de, which is larger covering the epistome and the anterior antennas.Within the species, there are two different colors. The “yellow” color has a yellow or bright orange exoskeleton, with white spots on the underside of the locomotor legs and claws. The \u201cpurple\u201d color has a dark purple exoskeleton, but with the same white spots as on the yellow profile. Some intermediate individuals exist, they are mainly yellow, but with purple spots on the shell. On the island of Ascension, the yellow color is the most frequent, while on Atol Das Rocas, the distribution is more equitable. Dark individuals are better hidden from predators, but more subject to thermal stress for long migrations. The Das Rocas Atol is much smaller than the Ascension Island, and the migration roads are therefore shorter, which can explain the frequency difference between the two colors. The species was described for the first time in 1837 by Henri Milne Edwards under the name Gecarcinus Lagostoma With the equipment sent by naturalists Jean Ren\u00e9 Constant quoy and Joseph Paul Gaimard, collected by the French ship L’Astrolabe.
