Mysterious long crab species by car in the Pacific Ocean

An adult spider has a length of two to as much as 4-5m, as long as a 4-seat car.

The undersea world is always mysterious and captivating. Although the science and technology has been modern, submarines are diving deeper, but have not yet discovered the ocean floor. As for crab species, there are countless subspecies on the sea floor.

However, in the family, the Pacific spider scientists are the largest known species in the world. This giant crab species lives on the Japanese seabed, so it is sometimes called Japanese spider crab .

Because the giant crabs, shaped like spiders, live on the seabed, the information about them is still mysterious, except that their meat is very fat and nutritious and the gourmets know it well.

The scientific name of spider crab is Macrocheira kaempfer . Japanese people call them high leg crabs.

Scientists have calculated and concluded that spider crabs possess the longest foot among the crustaceans. While the copper crabs only have a length from head to head and about 10cm, an adult spider has a head length of 4-5m, as long as a 4-seater car.

Its protruding legs support the body about half a meter across and weigh up to 20kg.

People often call long legs as women, while for crabs it is the opposite. The male crabs have long, long legs, and the female legs are quite short. Even more, its pair is shorter than the legs.

Although spider crabs have aggressive, pitiful looks, the observers think of giant poisonous spiders eating humans in movies, but in fact they are quite gentle. They take advantage of sponges or other creatures to disguise themselves, avoiding their opponents rather than trying to defend themselves and attack again. Meet the enemy, they can only count on the hard shell, like the neck-necked turtle.

Giant spider crabs are found on the southern coast of Honshu Island, from Tokyo Bay to Kagoshima and some more remote areas. Giant crabs, weighing 15 to 20 kg, are usually found only at depths of 500-600m on the seabed, where few species can withstand water pressure and darkness.

It is also because these giant crabs live at such terrible depths, that humans rarely catch them. The life of this crab is still a mystery to humans.

The food of giant spider crabs is shellfish and shellfish. Their favorite dish is rotting corpses. The life cycle of spider crabs is also in the great sea. Scientists believe they can live up to 100 years. The crabs with this age reach this threshold, their weight also reaches the maximum level.

Because these crabs are very tasty for meat, they are hunted aggressively. The center of spider fishing is located in the Suruga Bay of Japan.

It was recorded that the harvest of spider crabs in 1976 reached a record of 247 tons. However, the exploitation output is declining gradually. By 1985, the number was only 32 tons.

In recent years, although equipped with modern facilities, but the output only reached a few tons per year. Crabs caught are usually not very large, with lengths of less than 1m. They are only caught when they get lost in shallow waters.

Recently, public opinion was disturbed when a Japanese fisherman caught a spider crab weighing 15kg, with a stratum reaching 2.4m. Immediately, this crab was transferred to Ho Chi Minh City. Germany's Munich to nurture.

According to scientists, this crab is about 30-40 years old. It will have 60-70 years of growth and its weight will continue to increase. However, compared to the crabs that were caught and on the disc, this 15kg crab is only in the shrimp category.
