How big is the biggest lobster in the world?
In 1934, a big lobster was caught off the coast of North America. It was 1.22 meters long and weighed 19 kilograms. Its tentacles were several feet long, its eyes and eyestalks were thicker than the thumb, and its body was as big as a dog. Up to now, it has kept the record of the largest lobster, which can be said to be the largest lobster at present.
Lobster is the largest species in the shrimp family, among which the embroidered lobster is the largest species, and the longest life can reach 100 years old. Lobsters wear helmets and armour. Armor? Very hard, with many thorns on the head and chest, two long barbed tentacles, and ten stout feet. Lobsters have no other weapons except thorns in the head and chest. They are slow and clumsy and easy to catch. Lobster lives in a warm ocean. It lives on the bottom of the sea, hides in the crevices of rocks during the day and comes out for food at night.
So it seems that lobster is the biggest among shrimps, but the latest research shows that. The world's largest shrimp should be kiwi shrimp, which is a kind of extinct large invertebrate. Fossils show that the mouth of the shrimp has more than a dozen rows of teeth, with a diameter of 25 cm, and the fecal fossils are 10 cm long and 5 cm thick. It is speculated that the body length of kiwi shrimp may exceed 2 meters. Strange shrimp was first discovered in Canada. At that time, only a fossil of its front paw was found, which was mistaken for the tail of a shrimp. Scientists also imagined a shrimp head, which was named Qixia because it was not a shrimp.
Strange shrimp fossils show that this animal's mouthparts have more than a dozen rows of teeth, with a diameter of 25 cm, and the fecal fossils are 10 cm long and 5 cm thick. It is speculated that the body length of kiwi shrimp may exceed 2 meters. It is the largest known CAMBRIAN animal.
A British fishing boat recently? Captives? I bought a giant pink lobster five times the size of a normal lobster. It is reported that this big male guy with claws and claws is 6 1 cm long and weighs about 4 kg. English lobster king? . Marine biology researchers said that this lobster belongs to the class of chelonian lobsters, because of its? Full of energy So it is affectionately called by fishermen? Poseidon? Poseidon in Greek mythology 。
According to the BBC, this one? Big Mac? It was accidentally discovered by fishermen at a distance of 32 1 km southwest of Cornwall Peninsula. Experts said,
Although this huge lobster is common in the local area? Crawfish? Consanguineous, but because of its physical size? Great? , so was sent to the aquarium.
? Pension? . On the same day, fishermen caught three big lobsters, except? Poseidon? In addition, two other smaller lobsters have been sent to the fish market.
Aquarium staff said that from? Poseidon? Huge body, it should be at least a bit? Grandpa lobster? Relevant information shows that what is this giant pink crayfish and ordinary crayfish? Relatives , often found on the west coast of Africa and the Mediterranean region. Because they are huge compared with ordinary crayfish, they can survive 600 meters below sea level. Although? Poseidon? Fall into the fishing net, but get rid of the fate of Chinese food on the plate with the help of body advantage.
According to reports, at present, Poseidon? It has been safely escorted by two staff members to live in an aquarium, where some large crustaceans, such as Alastair horseshoe crabs and various lobsters, are also kept. Relevant parties believe that? Poseidon? Is the largest lobster in the history of the aquarium, and it is very likely to become? The largest live lobster in Britain? . Previously, the largest lobster caught in Britain was as long as 70 cm.
According to Guinness World Records, the world's largest lobster was caught in Nova Scotia Peninsula in Canada in 1977, and that lobster weighed about 19.97 kg. 1934 A giant lobster was also found in North America. It was about 1.2 meters long from the tail end to the pincer tip and weighed 19 kg. Its specimens are now displayed in the Boston Science Museum. In recent years, American fishermen have also caught a huge live male lobster weighing about 10 kg from the Atlantic Ocean.
Generally speaking, it takes five to seven years for an ordinary lobster to weigh nearly 500 grams from birth. Therefore, some experts estimate that the above can be called? Lobster king? I'm afraid all the big guys are nearly or over 100 years old. Some scholars believe that warm sea water and adequate food may accelerate the growth of lobsters. Therefore, it is sometimes not completely accurate to infer the age of lobsters simply from their size and weight.
The person concerned plans to apply for a world record. It is reported that this lobster is at least five times larger than ordinary lobster, and the person who captured it expressed great excitement.
It is reported that this lobster has been named Poseidon (Poseidon) because it is so huge. The captors said that it is not clear whether it can break the world record, but they are confident that it can break the local record in Britain, because this kind of big lobster is quite rare in the local area.
Because? Poseidon? It is so huge that it can live in an aquarium instead of being eaten.
There are more than 400 species of lobsters in the world, and North America is the continent with the largest distribution of lobsters. There are two families (Crabmeat, Crayfish), 12 genera and more than 300 species distributed in North America. Among more than 300 species of lobsters, most of them have low economic value, among which the species of Cambarellus is the smallest, and the individual weight rarely exceeds lg. Lobsters with large individuals (up to 50-80g per fish) and important economic value include Procambams, Cambarus, Pacifastacus and Orconectes, among which Procambarus clarkii accounts for 70-80% of the total lobster output.
China is one of the countries with the least distribution of lobsters, with only four species, namely Procambarus clarkii, Cambaroides dauricus, C.schrenkii and C.Similis. The last three species are only distributed in three northeastern provinces of China, North Korea and Japan.
The scientific name of freshwater lobster is Procambarus clarkii, which belongs to Arthropoda, Crustaceae, Shrimp Family and Procambarus, and it is one of the most valuable species in the genus Procambarus. The shrimp has strong adaptability, can widely live in freshwater lakes, rivers, ponds, ditches and rice fields, and is mainly distributed in Jiangsu, Zhejiang, Hubei, Hunan, Anhui, Shanghai, Shandong and other provinces (cities) and regions 10, and is basically a natural wild resource.
The way to identify a female lobster is to see if there are a pair of triangular spines on the lower epidermis of the head-body connection part of the shrimp, and if there are, it is a female crayfish.
Australian freshwater lobster is called freshwater lobster because of its large size, somewhat similar appearance to sea lobster and only living in fresh water. Its individual generally weighs100 ~ 200g, and the largest individual in Australia can weigh 500g. Its appearance is beautiful, its body color is brown-green, its head, chest and abdomen are evenly connected, and it is covered by a hard shell, and it has 5 pairs of pectoral feet, which are covered by a hard shell. The first pair of pectoral feet is particularly developed and becomes a powerful claw. The male's claw is more developed than the female's, and there are 1 membrane bright red bands on the outside of the claw, while its head has 6 tentacles and its tail has 5 tail fans.
