Seeing that the day of the Arrival of the Russian King Crab is getting closer and closer, Xiao Jiu found that the King Crab is not a crab! The jaw is going to fall off...
First, let's take a look at some common crabs. From left to right, there are pike crabs, green crabs, and common river crabs.
What do we have in common? That's right, they're all eight legs, two pliers.
PS: PS: Pliers are not responsible for walking
Next up is the king crab!
Obviously, the king crab has only six legs and two pliers, so they are not a species.
In fact, although king crabs look like crabs and taste like crabs, they are indeed not crabs, but belong to the stone crab family (six legs). This and crayfish, Boston lobster (lobster family) and not lobster (lobster family) are a truth. Don't look at the size of king crabs, there is a theory that they are actually the ancestors of small hermit crabs. But in any case, these two stone crabs are close relatives who have not run.
Snow Crab vs King Crab
In addition, it should be noted that there is a crab called snow crab, as shown in the following figure, it looks similar to the king crab, tastes similar, eats similarly, and the origin is similar, plus the alias of the king crab [snow crab] and the name of the snow crab are similar, so the two are often confused. However, snow crabs have eight legs and are real crabs, and the biological differences between the two are actually very large.
King Crab vs Emperor Crab
There are also many people who can't tell the difference between king crab and emperor crab. King crab generally refers to Kamchatka quasi-stone crab, not real crab, belongs to the decapod order Crooked-tailed suborder Stone Crab family. The emperor crab refers to the giant pseudo-coastal crab, native to Australia, belonging to the decapod short-tailed suborder Fan Crab family. The two should not be confused.
King crabs are large, weighing up to 10 kilograms at large. King crabs grow slowly and can live up to 30 years. On the outside, the king crab is about 25 cm wide and has legs about 1 meter long, which is the largest of the crustaceans. The whole body is covered with hard thorns. The legs of the king crab are long and thick, and 3 pairs of feet are visible except for a pair of claws. The chelate on the left is slightly larger than the one on the right. In addition, most crabs seen are generally seen moving laterally. King crabs can move not only laterally but also vertically.
King crabs fall into three categories: Red, Blue, brown. The best meat is the red king crab. The average king crab can survive for more than ten years at most, and continues to grow to a very considerable size. According to records, the largest king crab caught so far weighed 25 pounds and had its legs open to be six feet long. The average live king crab sold in the market is 3 to 6 pounds.
King crabs are caught using a strong barbed wire fence, making a large square trap cage, in which fresh fish, clams, etc. are placed as bait and sink to the bottom of the sea. By the way, the crab has a fatal injury, that is, it can't resist the seafood feast! And also a connoisseur of food. Fishy fishy, it's scornful! As long as it's the freshest, best seafood, on the knife mountain or down the oil pot, they're absolutely obligated and automatically online.
King crabs belong to the deep-sea crab class, living at a depth of 850 meters and living at a water temperature of 2-5 ° C. The minimum water temperature at which king crabs can survive is 1.4 degrees Celsius.
After pulling so much, in fact, I know that what you are most concerned about is:
Can you eat king crab!
As we all know, the sea around China does not produce king crabs, so most of the king crabs in the Chinese market are imported quick-frozen. The fishing areas for king crabs throughout the Far East are concentrated in the waters of Japan as well as in Russia (yes, Russia is also a major producer of king crabs). Due to the Japanese nuclear leak in recent years, the fishing of king crabs has been concentrated in Russia, but China has never imported fresh king crabs directly from Russia.
Speaking of Russia, this is a coastal fishing country in an extremely cold but resource-rich country. It straddles the Eurasian continent, borders the Arctic Ocean to the north, the Pacific Ocean and the Atlantic Ocean to the east, and the surrounding peninsula has many seas and excellent hydrological conditions, so its catch and seafood are also very diverse, and the pure and cold sea waters produce many high-quality seafood such as flounder, mackerel, cod, squid, sea urchin, shrimp, scallops and sea cucumbers.
As for king crab, Russia is the world's earliest fishing country, starting in 1950, and has been fishing for nearly 70 years, not only the quality of king crabs, but also very rich experience in fishing operations.
