Spider crabs are collectively referred to as invertebrates of the crustacea subphylum Crustacea, the order Malacostraca, decapoda, and the family Majidae or Maiidae.
Spider crabs are a species of sea crab that grow in Alaska, USA. Because of its eight legs, it looks like a spider, and has more antennae than ordinary crabs, so it is called spider crab.
The Jiaolong manned submersible, which performed its first pilot application voyage in the South China Sea, dives to the bottom of the sea and collects valuable seabed samples such as spider crabs and cold corals.
Spider crabs have a hard shell with the longest preclave of crabs, so named because of their resemblance to spiders. The body is thick and round, the feet are slender, and usually slow to move. Most are scavengers, especially carcasses.
Spider crabs have spine-like dorsal carapace, sharp gang feet, and long walking feet. This spiny spider crab is the largest crab in Europe, with nearly 100 different species off the coast of Australia, and although they have long claws, eight slender legs, and look like spiders, they are sluggish and easy to catch. There are many raised round balls on the shell of the spider crab, which are actually sea anemones, which look like flowers, but are a carnivore that feeds on animals in the water. It is attached to the shell of the spider crab, and the spider crab is "mutually beneficial".
Because spider crabs like to roam around in the sea, this makes the originally immovable anemone expand the foraging field as the spider crab moves. For spider crabs, one is that sea anemones can be camouflaged. Second, because the anemone can secrete venom, it can protect spider crabs from predators and ensure the safety of spider crabs. Spider crabs protect themselves with sea anemones, and their crawling provides convenience for sea anemones to prey, a phenomenon that biology calls "symbiosis".
Spider crabs generally live at depths of 3,600 meters on the ocean floor, but sometimes they climb to shallow sands; especially during breeding, they will climb to the beach in large groups, when fishermen will take advantage of the opportunity.
Spider crabs live by preying on fish, and the pair of pliers on its body are very powerful, and it is difficult to escape the "clutches" after the prey is targeted by it. Spider crabs undergo about 14 molting shells in their lifetime, and each molting is a challenge to life, after which its body will become extremely tired, unable to stand, and quietly lie on its stomach for several days. Outside the molting period, spider crabs are fierce and aggressive, and belong to the "big brother" in the crab family. 50,000 spider crabs can also participate in the mating event at the bottom of the 4-metre-deep seabed of Philips Harbour in Melbourne, Australia.
Spider crabs generally weigh 1 to 2 kilograms per piece, all of which are natural wild imports, crab meat is delicious and rich in protein, and is mainly sold to high-end hotels in Fuzhou. Because it has high environmental requirements, it is easy to die in the process of transportation and temporary maintenance, and the ordinary market generally does not sell, so if the public wants to buy, they need to book with seafood wholesalers in advance.
The price of live spider crabs in restaurants is about 500 yuan per 500 grams, and the price of dead crabs per 500 grams is about 200 yuan; and in fuzhou Xiyingli and other markets, the price of live spider crabs per 500 grams is about 280 to 380 yuan according to the market, and the dead crab is about 100 yuan.
Spider crabs are cooked in the same way as other crabs, suitable for steaming, and another method is to cut the spider crab into small pieces, then add salt, monosodium glutamate, chicken essence, rice wine and marinate before adding it to the oil pot. When it is 60% hot, first put the crab shell into the oil pan, and then put the marinated crab pieces into the oil pan with starch, fry them until golden brown, and then fish them out. Then put the green onion and dried chili peppers in the pan and simmer, pour in the salt and fried crab pieces, and stir-fry. In addition, it should be noted that spider crabs, like other crabs, cannot eat melons within three hours after consumption, otherwise they will cause symptoms of poisoning and diarrhea.
