Spiders and crabs are both arthropods, so why can t spiders eat them?

Many people are very fond of eating crab as a seafood food, and they think that this food is also very delicious. But there are also many netizens who indicate that spiders and crabs are arthropods.

Why is it that crabs can be used by people, but spiders can't? Personally, I think crab is a seafood substance, which is why it can be used by people. But spiders are a kind of harmful insects, if people eat spiders, then it will also have a certain harm to themselves, after all, spiders are still a poisonous substance.

Crabs and spiders are not the sameAlthough spiders and crabs are both arthropods, they are also very different in many ways. Some spiders are very poisonous, which can cause some trouble and distress to people. However, there are many crabs that are rich in protein, so people can also have certain benefits for the body after using them.

Either way, I want people to be able to look at both items in a reasonable way. Don't think that they are similar in kind, so you can eat them, in fact, this practice and thinking is also very incorrect. <>

Eating crabs rationally Crabs are creatures that are not difficult to see, whether at the dinner table or in everyday restaurants. There are a lot of people who like to eat crabs because they think they are very delicious. And some netizens said that crab is also very nutritious, and the protein it is rich in is really very much.

There are many people who like to eat crabs, although eating crabs is a good thing and performance, but people can't eat too many crabs. In this case, it will also cause some damage to the body, and it will also bring bad effects and trouble. I hope that people can take a reasonable view of crab as a seafood food.

For crabs and spiders, although they are both arthropods, they are also different to a large extent. I hope that people can face crabs and spiders reasonably, and don't confuse the two creatures, so that there will be bad phenomena and behaviors. After all, spiders are poisonous animals, and they still have a lot of harm to the human body.

I hope people don't think that spiders are edible creatures, after all, they are still very poisonous.

The food of spiders is mainly insects, and the bodies of these insects contain a large number of toxins, and the body of spiders will also accumulate these toxins, and if a person eats a spider, he will definitely be poisoned, resulting in death.

Both are arthropods, crabs are crustaceans, spiders are arachnids instead of insects, crab shells are meat, and spiders are estimated to burst pulp when they bite into it, so spiders can't eat it.

Because spiders are very poisonous, they will bring a lot of bad diseases to the human body, but crabs belong to seafood, so spiders cannot be used.

Because most spiders are poisonous, eating them will cause diseases in the body, which will outweigh the losses.

Arthropods, of course. The first thing to understand is what an insect is? What is the definition of an insect by biologists?

Insects, however, have some common features: their bodies are segmented, forming three parts: head, thorax, and abdomen. on the head there is a pair of antennae and a pair of round, large compound eyes; The thorax usually has two pairs of wings (there are also some species that have only one pair of wings, such as flies, mosquitoes, or completely vestigial wings, such as fleas, lice) and three pairs of legs.

Entomologists all recognize these characteristics as the criteria for identifying insects. And the structure of the spider: the spider's body is divided into only two parts, that is, the head and thorax are combined into one part, and the other part is the abdomen; without antennae and wings; There are four pairs of legs.
