There are too many fish in the sea that are toxic, but we ordinary people generally can't get in touch with them. Only fishermen and fish research experts at the seaside will meet or find them. Most of my knowledge in this field comes from programs like Animal World. Let me give you some examples:

First, the stone fish. This is the most impressive marine fish with extremely strong toxin, which looks like a stone. I don't like to move at ordinary times. I always pretend to be a stone. If you accidentally step on it, the consequences will be unimaginable.

Second, the devil fish. We can see this kind of fish in the aquarium, swimming around in the sea like a big bat flying in the air, so its scientific name is manta rays. This kind of fish has a slender tail with stings at the end, which is very toxic.

Third, the lion fish. The scientific name is Migu, which is a kind of fish that looks extremely poisonous because it has thirteen colorful stingers on its back. It is precisely because of these long stingers that it looks like a lion with mane, so it has this name.

Fourth, tigerfish. Speaking of lionfish, there is also a kind of marine fish called tigerfish, which is also toxic and even famous among fishermen. Although its toxicity is not fatal, it can make people feel particularly painful. It's like being stung by a scorpion, so it's also called a sea scorpion.

Five, puffer fish. Although it has the word "river", it is really a marine fish. Because a few kinds of puffer fish entered rivers and were caught by the ancients, they made sounds like pigs, so they were named puffer fish. As we all know, the blood, liver and roe of puffer fish are poisonous, but the meat is delicious. Many people risk their lives to eat puffer fish, and I admire it.
