[22], The red king crab has five sets of gills used for respiration, which are in the branchial chamber within the carapace. [23]:654 The Frank-Starling mechanism is a little different in crustaceans, as it involves the cardiac ganglion as described previously. The leech is connected with the crab in the Pacific, but has not yet been recorded in the Barents Sea. Final Score = geometric mean of the four Scores (Criterion 1, Criterion 2, Criterion 3, Criterion 4). and echinoderms are the main prey items, but also dead fish and algae are eaten by the crab. The species was first introduced the Barents sea in the 1960s, and since then first found in Norway in 1977. The species is native to the Bering sea and was introduced to the Barents Sea around Murmansk in north west Russia in the 1960s. A female crab may spawn from 25 000-400 000 eggs, depending on body size. [18], The red king crab has a wide range of tolerance to temperature, but it affects their growth.

Juveniles are consistently hyposmotic to the seawater because they have lower sodium concentration in their hemolymph. In Zelenetskaya Bay (Dal’niye Zelentsy settlement area), for example, a decrease in sea-urchin biomass by a factor of 5 compared to the period before the Red king crab introduction has been recorded. [24]:303–306Paralithodes camtschaticus has an open circulatory system with a dorsal, ostiate heart. The successful reproduction and high abundance of the crab in the Barents Sea show its ability to adjust to the environmental conditions of the region, such as polar day and night and the seasonal characteristics of biological processes typical for high latitudes. [26] Due to the environment to which it is exposed, the posterior gills of the crab can also be cleared of parasites and sediment by increasing the movement of its fifth set of primitive legs.[27]. The crabs were transported by aeroplane to the Barents Sea. [24] The water is drawn in from behind the walking legs then expelled from the branchial chambers through the tubes called prebronchial apertures, which are located beside the mouth. A decrease in individual fecundity might be evidence that the crab abundance in the Murmansk area already has reached its limit, and natural mechanisms restricting population growth have started acting.

[2] It was named after the color it turns when it is cooked rather than the color of a living animal, which tends to be more burgundy. In the east it has likely already reached its distribution limits. The Red king crab has not changed its typical behavioural characteristics in the Barents Sea, despite the change in abiotic conditions. [6], Red king crabs are experiencing a steady decline in numbers in their native far east coastal waters for unclear reasons, though several theories for the precipitous drop in the crab population have been proposed, including overfishing, warmer waters, and increased fish predation. The carapace encloses two branchial chambers that enclose the gills. Step out and brave the rough Barents Sea to catch a new type of prey: The king crab.
