Hundreds of thousands of spider crabs were attacked by stingrays when molting, stingrays eat spider crabs, one bite like eating noodles, why are stingrays so strong? It is said that stingrays have also killed people, is this true?
Every year in June, hundreds of thousands of spider crabs in Australian waters will swing their slender legs to crawl out of the deep sea, slowly go to Phillip Bay south of Melbourne to participate in a molting conference, among the more than 60,000 species of crustaceans currently known, spider crabs are the largest, the largest spider crab, two claws stretched out up to 4 meters long, is the "big brother" in the crab family, but spider crabs want to grow so big, it is not easy, like most crabs, The spider crab's body has to molt every time it grows.
When molting, spider crabs will drink a lot of seawater, let their bodies swell up, use the difference in water pressure to hold out a crack in the old shell, and then crawl out of the old shell with all their strength, complete the "crossing robbery", it is reported that the spider crab's life will experience about 14 growth molts, and each molt, for spider crabs, is a life and death experience, the degree of pain is no less than rebirth, after molting the old shell, spider crabs are like newborn babies, very fragile, their newly grown shell, It takes a few days to gradually harden, during which time, due to the loss of the protection of the old shell, coupled with the large amount of physical energy expended when molting the shell, the usually arrogant "crab king" will become weak.
In the eyes of predators, spider crabs at this time are a delicious meal at your fingertips. Sure enough, after the spider crab army completed the molt, a group of stingrays appeared on the battlefield like "ghosts", stingrays more than 1.5 meters long shuttled through the spider crab army like a kite, it is obvious that it is selecting the fattest target to start, once the target is identified, the stingray will suck the spider crab into the mouth like noodles, accompanied by a creaking chewing sound, the stingray eats all the way, leaving a lot of bones along the way.
Hundreds of thousands of spider crabs, in the face of stingray attacks, naturally there are some coping strategies, spider crabs with some strength will quickly gather up, as if in the stacking of arhats, piled into a hill, want to rely on momentum to scare off the invading enemy, but the effect is obviously not good, stingrays as always in an elegant swimming style to the spider crab battle, lightly patted the spider crab put out of the "array" to break through, stingrays understated and ate again, without caring about the face of spider crabs, Under the wingspan of the stingray, no place is absolutely safe, whether it is piled up into a hill, or hiding under the seabed, it cannot hide from the stingray, an adult stingray hunting range can cover several square kilometers, and when the stingray is satisfied with the "buffet", a spider crab carcass is left on the bottom of the sea.
Spider crabs gathered together to molt, on the other hand, it is also successful, after all, the spider crabs that are eaten are only a very small part, the vast majority of spider crabs can successfully survive the "molting period", and return to the deep sea, the so-called "dead poor road immortal friends", spider crabs huddle and molt, gambling is luck, as for whether to repel strong enemies, or feed strong enemies is not so important.
After returning to the bottom of the sea at a depth of 3,600 meters, spider crabs mainly live by eating rotting animals and plants, and if they can encounter whales that sink to the bottom of the sea after death, it is simply lucky. Spider crabs don't have to worry about eating for a long time. Its ugly stingray, or a poisonous creature, has the title of "poisonous" lonely sword in the ocean, you may not believe it, the stingrays that seem harmless to humans and animals have also killed people.
In 2006, the world-famous animal protection activist Steve Owen, when filming a documentary underwater, was stabbed in the chest by a short-tailed stingray about two meters long, stingrays usually have 1-3 black stingers, stingers up to 30 centimeters, in danger, stingrays will wave their tails to attack, once the stingers on the tail stab the enemy, they will inject toxins, stingrays are fully secreted toxins, and will cause unbearable pain after entering the body. Muscle spasms, swelling, heart failure and eventual death.
Steve Owen died after being stabbed by a stingray due to poisoning and heart injury. Although stingrays are usually docile and do not easily attack people, there are exceptions to everything, and if people swim above them, they will make them feel threatened. Or when stepping on stingrays, it will actively attack human possibilities, globally, stingrays cause death or injury almost every year, in July 2018, stingrays haunt the shallow waters of Jersey, England, experts also issued a warning, advising tourists not to swim in the water, which shows the scary thing about stingrays, thank you for reading. #I'm going to make micro headlines ##spider crab##黄貂鱼 #
