In April, 2012, the “sea life” aquarium in Weymouth, UK, purchased three crabs from Australian fishermen intended for exhibition intended for 3000 pounds (about HK $37700) to save some of this crustacean. One of the Tasmanian king crabs, whose shell is about 38 cm wide and weighs 7 kg, is still growing. It is known as the largest crab ever displayed in the UK. According to the daily email from the UK, the Australian giant king crab offers finally escaped the cooking pot and will be sent to the British aquarium intended for exhibition. Britain will exhibit giant king crabs, each with only 18 Jin of crab meat. Tasmanian king crab is really a delicacy in Australia. Each local crab can have 20 pounds of crab meat, but the staff from the aquarium still feel sorry for the huge crab that was eaten. [1]
According to the record published in the journal Proceedings from the Royal Community, Part B: Bioscience, Emperor crabs may have lived in the area intended for thirty to 40 years, and the destructive environmental impact of rising water temperature has led them to climb higher. The higher the water temperature in Antarctica, the higher the water temperature. So far, Emperor crab has not migrated to the main part of the continental shelf located at a depth of 500 meters. Scientists worry that if they climb the main continental shelf, they may cause great ecological damage. This kind of crab, which is often cooked for its meat, is huge, which means that they will naturally become the top predator in the waters where they appear. [3]
The purpose of this diving gear to dive into Palmer deep is to study the marine life there, rather than deliberately looking for crabs. If so numerous crabs are found in this area, its regenerative populace will be amazing. The research team is led by Craig Smith from the Department of oceanography at the University of Hawaii in Honolulu, USA. The research team said: “for a lot more than 14million years, lithodidid crabs happen to be reluctant to enter the chilly waters from the Antarctic continental shelf. The western part of the Antarctic Peninsula is heating up rapidly, and scientists believe that lithodidid crabs may invade here quickly. ” A remote-controlled submarine was used to investigate Palmer deep, a mud mattress basin 120 kilometers below the continental shelf from the Weddell Sea, and a large number of regenerative populations of stone crabs were discovered, which provided first-hand evidence to prove that king crabs have crossed the Antarctic continental shelf.
