In fact, people have long known that Jiuzi and Long Jiuzi are different, but if they really appear in industries that we don't often contact, we will feel very shocked. For example, most of our common soft-shelled turtles are blue-brown and some are yellowish, but many people who are pure yellow are rare, but they do exist. As the saying goes, the world is big and everywhere. But when we encounter these novel things, don't be nervous, let alone panic. In fact, these are normal natural phenomena.
When it comes to genes, many people are both familiar and unfamiliar, mainly because many of us are not engaged in related industries and will not be exposed to related concepts, but genes are everywhere. We humans have children, and the replacement of plants is the inheritance of genes. However, some changes will occur in the process of gene inheritance, but due to the stability of genes, the probability of change is very low, so many creatures we see are familiar, and occasionally we will see some special results, that is, gene mutations.
Most of the crayfish that many people have seen are red or blue, and few are blue. In fact, this is also the result of gene mutation. Many people like to meet this mutant species. As the saying goes, things are rare. Once the mutant species are obtained, they can be used for reproduction and sold at high prices to satisfy the public's curiosity. At present, the more successful example is koi fish. The appearance of various colors in koi fish is also caused by gene mutation, and then relatively stable characters are formed through generation selection.
In fact, in life, there are many examples of this kind of body color change, such as white crow, white elephant and so on. But all the mutation probabilities are very low, some are one in a million, and some may be one in a million, so it is not common.
You can keep it if you like. My roommate once bought blue and ordinary ones at the waterfowl market. It looks better. The food is better, too Just put some nematodes in it. Unfortunately, my roommate didn't live to the end for various reasons.
1. It is said that the blue color of blue lobster is not caused by pollution. If the color turns blue due to environmental pollution, most lobsters will turn blue, but now this kind of blue lobster is extremely rare, so I think it should be caused by extremely rare genetic variation.
2. The body color of crustaceans such as shrimps and crabs is the result of the interaction between chitin and astaxanthin. When the combination of chitin and astaxanthin changes, the body color of shrimp and crab will also change.
It is reported that on June 9, villagers in Lingdong Village, Dagong Town, Hai 'an County, Jiangsu Province captured a blue crayfish, which attracted surrounding residents to watch and shoot. Comparison between blue crayfish and common red crayfish. Crayfish are all blue, even their beards are blue. Because of its unique color, it is particularly cute with local ordinary crayfish. It is understood that this single-chelated blue lobster is a rare genetic variation phenomenon, with an average of/kloc-0 per lobster. Aquatic experts say it may be caused by genetic mutation, but the number is very small. Doesn't mean it's caused by environmental changes.
Blue crayfish is a rare species of crayfish. The probability of blue lobster appearing in crustaceans is one in two million. The reason is that the lobster with gene mutation will produce excessive protein, and this protein reaction will form a blue compound-shrimp cyanin, which will make its shell appear bright blue. But it doesn't help lobster at all. Compared with the surrounding environment, bright blue makes blue lobsters easier to be found and killed by predators. Most shrimps are dark blue or brownish green. Generally speaking, when people cook them, they will appear red. Although blue lobsters are not the rarest genetic mutations known, they are the most striking and easier to be found and hunted by carnivores. This blue protein is the only visible color in shells (not meat).
I saw someone catch it in the news before, and it should be a mutation!

Blue lobster, a rare genetic variation of American lobster, is a rare marine creature comparable to living fossils, with/kloc-0 per blue lobster appearing in an average of 2 million lobsters.
Blue crayfish experts say that the probability of crustaceans having non-environmental causes is one in two million. This makes them look cool. Lobster with gene mutation will produce excessive protein, and this protein reaction forms a blue compound, shrimp cyanin, which makes its shell appear bright blue. This doesn't help lobsters at all. Compared with the surrounding environment, bright blue makes them easier to be found and hunted by predators. Although blue lobster is not the rarest genetic mutation in known lobsters, it is the most striking. This blue protein is the only visible color in shells (not meat). Blue lobster is safe to eat. But, you know, cooking will destroy this kind of protein. Cooked blue lobster is no different from other non-mutated compatriots.
This is farmed shrimp. I drank a lot of ink.
The color of shrimp shell is mainly formed by chitin cyanin and astaxanthin in the shell. According to the different content and combination degree, it can present a variety of colors such as red, orange, blue, cyan, white and black, such as Australian lobster, which is mostly blue. The blue crayfish appearing on the Internet is probably the genetic variation of the individual crayfish, which is not unusual and has nothing to do with heavy metal pollution.
