Spiders and crabs are so similar, why are spiders so unpalatable?

Because spiders are smaller than crabs, although the two are similar in appearance, they are not the same in size, the size of crabs is several times the size of implants, and crabs have crab meat and crab roe.

We don't have large-scale edible spiders, it's just that spiders didn't make it into our recipes in times of food scarcity. To sum up, there is no habit of eating them. Nowadays, people in some regions are very fond of eating spiders, such as some countries in Africa and South Asia.

Spiders are excellent protein for the people there**. There are also some countries that do not eat crabs because for them there is enough fish stocks. Even spiny freshwater fish are not worth eating.

Because the spider's muscles are liquid powered, and the spider doesn't have crab pincers and crab roe, no one wants to eat it.

Although spiders and crabs are similar, the substances in the bodies of spiders and crabs are actually different, so the taste is definitely different.

Spiders and crabs are relatives.

Spiders belong to the phylum Arthropods, Arachnida, Arachnida, Arachnids, Crabs also belong to the phylum Arthropods, Crustacea, Decapods, reptiles, so spiders and crabs belong to arthropods, so they are relatives and a family.

The relationship between crabs and spiders is that they belong to the same phylum Arthropods, they are two branches belonging to different orders of the same phylum, spiders belong to the phylum Arthropods, arachnids, arachnids. Crabs also belong to the phylum Arthropods, Crustaceans, Decapods, reptiles, therefore, spiders and crabs belong to the same phylum.

Spider crabs, also known as pike crabs or spider crabs, are large, square-shaped and have eight legs, and generally inhabit the seabed or rocks. Although the spider crab seems to have a lot of appetite, it is not suitable for human food for the following reasons.

First of all, spider crabs have very little meat and a poor taste, and are often considered to be a kind of inferior seafood, with insufficient tenderness in the flesh, not rich in meat flavor, and a special chewy sensation when chewed. Compared to its Daqingta seafood, the taste of spider crab is not outstanding.

Secondly, there are more parasites on spider crabs, which can survive and reproduce in the liver and blood of spider crabs, and parasites can cause harm to human health. Therefore, if not treated and cleaned rigorously, spider crabs can become a potential food safety hazard.

Finally, spider crabs are highly toxic and often grow in low-oxygen environments, which can affect human health if they are not treated with special methods. Therefore, even though spider crabs look tempting, they are not recommended to eat them.

In summary, due to the poor taste, parasites and toxins and other problems of spider crabs, they cannot be liked by the majority of people like shrimp, crabs and other seafood, and are more suitable for ornamentation or scientific experiments.

Spider crabs can be eaten. Spider crab weight generally up to 1 2 kilograms, all are infiltrated and slippery and quietly imported in the wild, spider crab meat is delicious, egg bush limbs are rich in white matter, mainly sold to high-end hotels in Fuzhou.
