The crab Bythograea thermydron has eyes that consist of large naked retinas. Oxygen consumption rates of the brachyuran crab, Bythograea thermydron, from the Galapagos hydrothermal vents were measured at temperatures of 2, 8, 12, 18, and 25 C; … The first bythograeid vent crab to be described was Bythograea thermydron in 1980. Bythograea intermedia was originally described based on six early crab stages and a megalopa, in a sample that was mixed with B. thermydron specimens from the original collection of the Galapagos Rift studied by Williams . We tried to … The structure of a well-known neurohormone involved in homeostasis regulation and stress response, the crustacean hyperglycemic hormone, was investigated in the deep-sea hydrothermal vent crab Bythograea thermydron.The neuropeptide was isolated from neurohemal organs (sinus glands) and its biological activity checked using an homologous bioassay. This study investigates the salinity tolerance and the pattern of osmotic and ionic regulation of Bythograea thermydron Williams, 1980, a brachyuran crab endemic to the deep-sea hydrothermal vent habitat. Geryon longipes and Bythograea thermydron are the most abundant deep-sea crab species in their respective environment. Journal of Shellfish Research . In 1977–79, brachyuran crabs were collected in hydrothermal vents around the Galapagos Rift, allowing description in 1980 of Bythograea thermydron and the new family Bythograeidae (and the superfamily Bythogreoidea). Bythograeidae Williams, 1980 é uma pequena família de caranguejos que ocorrem em torno das fontes hidrotermais de grande profundidade. To improve our understanding of the environmental impacts exerted on the vent organisms, we have characterized the two manganese superoxide dismutase cDNAs (mitochondrial: mMnSOD and cytoplasmic: cMnSOD) of three members of the Bythograeidae (Bythograea thermydron, Cyanagraea praedator and Segonzacia mesatlantica), the only endemic crab family living in hydrothermal vents.

Associated catalogue records: 7426:Arthropoda:Bythograea thermydron Williams, A. 27:107-118. Williams first described the crab in 1980, placing B. thermydron in a new family (Bythograeidae) that shares morphological characteristics with the Xanthi-dae, Portunidae, and Potamidae. Bythograea thermydron, a brachyuran crab endemic to the deep-sea hydrothermal vent habitats, encounters concentrations of hydrogen sulfide of up to 318 μM.

About 160 of the crabs in various states of maturity were collected by means of baited traps, suction, and mechanical arm with the aid of the deep submersible, Alvin. Bythograea thermydron (pronounce Bith-OH-GRAY-UH ther-ME-DRAWN), also known as the vent crab, is a white crab that lives in the Pacific Ocean, about 13,000 feet (3,962 meters) below the surface, where they live among hydrothermal vents or black smokers.In can grow up to about 4 inches (12.5 cm) in width. [3]Alimentam-se de bactérias e outros organismos das fontes hidrotermais. Fig. For Bythograea thermydron and C. antennarius, hepatopancreas was used. This is the dominant crab species on most vent sites along the East Pacific Rise and on the Galapagos Rift. The first centrifugation was at 800 g. The high-speed spins were at 8,800 g. For some preparations of B. ther- mydron, and all C. antennarius, an additional first spin at 8,800 g was per- Pronunciation.
