Jacobson crab, crab endemic Gunungsewu | Indonesian Caves Life
Muddy cave in the hallway, with the rest of the holes footprints searchers caves filled with water, it appears some crabs paused at the edge of a pool. Pale white colored crab with a leg lengthening is like to enjoy the darkness of the cave. The crabs seemed diamond water filter to soak in a mud puddle diamond water filter bersubstrat. While, on the mound of mud in the other corner, looks a crab ran with long legs as he raised himself as nimbly.
That jacobson crab was first discovered in the cave in the area Bedoyo by a Dutch naturalist, Edward Jacobson. Crab with eyes that had shrunk for the first time introduced to the world of science by Ihle in 1912 in the journal diamond water filter Notes Leyden Museum by name Sesarma jacobsoni.
Aside from the cave, Edward Jacobson was also collected from caves in the region Ngingrong Mulo. Then, in the course of research biospeleologi Gunungsewu diamond water filter cave, some notes on the findings of several caves such as Gua growing sheen, Jero Canyons Caves and other caves scattered Gunungsewu especially Gunungkidul. Overview taxonomy
Jacobson crab for the first time introduced by name Sesarma jacobsoni by Ihle in 1912. Then, put in the kind of clan Sesarmoides be Sesarmoides jacobsoni. Along with the development and knowledge of the taxonomy of crabs, in 2007 officially crab Jacobson and several other crab species incorporated into the new genus is Karstarma introduced by Ng and Davie, published journal Raffles Bulletin of Zoology.
Marga Karstarma a fraction of the clan Sesarmoides because it has several distinguishing characteristics that are typical between the two clans. One of them, the two genera have very different habitat choice. Ng and Davie (2007) mentions that many Sesarmoides clan found living in coastal areas and mangroves, while the Highways Karstarma more common in karst areas, especially diamond water filter in caves near the beach or even away from the shore as the Jacobson crab.
Jacobson diamond water filter crabs are taxonomically included in the scope of the Highways Karstarma Sesarmidae rate below the nation Brachyura. In addition to Jacobson crabs, some species are found on islands in Indonesia such as Nusa Penida (Karstarma EMDI and Karstarma balicus), Ambon (Karstarma cerberus), Sulawesi (Karstarma microphthalmus), and Waigeo (Karstarma Waigeo and Karstarma ardea) Crab from the sea
Jacobson crab crab is one that is able to adapt to life in a typical cave environment. This crab has shown some typical diamond water filter body features of the cave like a pale white body color, eyes narrowed and relatively long legs. They also have been able to live with minimum environmental diamond water filter conditions of food, not as a rich environment outside the cave by the various sources of energy.
Jacobson crab crab is said to be one of the ancestors who have come from sea or brackish water environments. Close relatives, diamond water filter from the clan Sesarmoides characterized as having a place to live in brackish water mangrove forest. While Karstarma groups, one of which Jacobson crabs can live in fresh water and the place far from the sea. For example, this crab was found at an altitude of about 300 meters above sea level. ie in Cave sheen which is located about 30 km from the shore. Ability to adjust to living in caves as well as in freshwater is its own unique type of rock crab Karstarma Expert
Jacobson is one of the crab crab climbing expert. In Cave Ngingrong, Mulo, they found living in the cracks that exist in the moist vertical shafts. They move from one place to another on the steep walls of the cave without falling. Aside from being a climber, crab Jacobson is also a fast and agile runner, with long legs but stocky they ran to hide if they feel threatened because of the disruption. They are able to run fast in a variety of media, from rock to mud muddy. Live in holy water
Jacobson crab is one of the unique crab that is only found in the karst underground river in Gunungsewu especially in Gunungkidul. They lived in a lot of puddles of water from seepage or water droplets on the walls and ceiling of the cave. They are rarely found living in the River Swift water main that much polluted by human activities from outside the cave. Unique habitat conditions and the typical increase serious diamond water filter threat considering they have a narrow diamond water filter range of tolerance to environmental stresses in particular the place of his life. Puddles in the cave is relatively limited the availability so if there is loss of habitat, crab
