Cuban crabs are red crabs, and there are toxic elements in their bodies, which will damage the intestinal mucosa of the human body, so they must be detoxified before they can be eaten. The dying or dead red crab will accumulate more and more toxic substances in its body. Even if it is cooked, it is not easy to destroy this toxicity, so don't eat the dead red crab!

Even puffer fish with giant poison can eat it. What else can be spared? For foodies, what they can eat is: "Four-legged ones are on the menu except tables and chairs, and hairy ones are except dusting and feather dusters". The more poisonous a poisonous snake is, the more valuable it is. The sand crab without meat can be made into sauce to eat, and all bugs are snacks should we have. Not to mention the swimming crab, this little sand crab can be made into delicious "sand crab juice"
