More than 50 million red crabs migrate in Australia:
As we all know, our people are involved in a very wide range of food culture, and the combat effectiveness is amazing, and the crayfish of invasive alien species can only meet people's needs by relying on artificial breeding.
Humans are the higher intelligent beings at the top of the food chain, and most of the wild animals are due to human activities, resulting in a sharp decline in populations.
Recently, a report about more than 50 million red crabs in Australia migrated, and everywhere they went, their eyes were red. It is understood that this is 16 years ago, and such a large-scale migration of red crabs was not seen in the region.
Why does no one dare to eat such a huge species, and why is this? Why do red crabs dare to appear near humans?
The Australian red crab, scientifically known as the "Christmas Island Red Crab", has a body divided into cephalothorax and abdomen, and the back of the cephalothorax is covered with cephalothorax, and the width of the shell is about 11.5 cm. The outer side is a compound eye with a stalk, and the abdomen is degenerate, flattened, and zigzagging on the ventral surface of the cephalothorax.
Red crabs belong to the marine species, with a black back shell and red abdomen and limbs, like cooked crayfish and hairy crabs. The limbs are very short and stout, and there is a lot of meat.
The habitat of the Christmas Island Red Crab is Christmas Island in the Eastern Indian Ocean, more than 300 kilometers south of the Indonesian island of Java, and is under the jurisdiction of Australia. Due to the special ecological environment of the region, from the end of each year to the beginning of the following year, hundreds of millions of red crabs mate on the seashore in the area.
Red crabs often haunt bushes, burrows at the bottom of tree roots, and disappear for two to three months of the year, which helps red crabs grow in tropical rainforests. During the rainy season, red crabs often go out for walks in order to breathe fresh and humid air.
It is understood that there are more than 30 kinds of endemic animals and plants on the island in the region, and this special environment also creates conditions for the diet of red crabs. Red crabs are actually omnivores, mainly eating fallen leaves, fruits, flowers, etc., but also eating dead crabs and birds, snails, etc.
On the island, red crabs have few competitors and are rich in food resources, with an average lifespan of 35 years. However, more than 50 years ago, because cargo ships carry invasive alien species African long-legged ants, which seriously threatened the population of red crabs, around October every year, there will be a large-scale red crab infestation in Australia, which is an important factor in the decline of red crab populations during the migration stage. Why can't humans prey on it?
At present, there are 50 million red crabs on the streets of Australia, and many red crabs are crushed to death by cars on the streets, why don't Australians eat red crabs?
There are many opinions about whether Australian red crab can be eaten, some people say that it can be eaten, and it is listed in the world's most famous seafood, so red crab should be a very delicious food. Some people think that red crabs cannot be eaten, because the body contains special toxins, which are easy to pose a threat to the health of the human body.
Comprehensive analysis, so the red crab is an edible species, but the relatively cumbersome processing process, resulting in many people do not understand it, mistakenly eat the red crab with toxins, resulting in food poisoning.
So what kind of poison is the poison in the red crab? Australian red crab has a certain degree of toxicity in the body, but this does not mean that eating Australian red crab is equivalent to chronic suicide! Australian red crab can not be eaten, because the red crab has a special toxic formic acid in its body, which will cause damage to the intestinal mucosa when eaten.
Why is it that when australian red crabs migrate, red crabs roam the streets and often haunt near humans? As a world-class gastronomic species that haunts the vicinity of the crowd, people are always blind to it, the main reason for which is that Australian law stipulates that inland fish, shrimp and crabs cannot be caught, which means that red crabs cannot be eaten (eating red crabs is illegal).
The status of red crabs in the world is very high, and although the red crab population appears on the streets on a large scale, the red crab population is also declining to varying degrees. In order to better protect the red crab, banning the killing of the red crab can effectively maintain the population of the best way.
At the same time, Christmas Island red crab belongs to Australia's exclusive species, in order to maintain the local ecological balance, Australia attaches great importance to the protection of red crab, its existence can protect the ecosystem and protect the earth.
