What five kinds of animals do "five poisons" refer to?

The "five poisons" in folklore are five kinds of animals, namely green snake, centipede, scorpion, gecko and toad. In fact, it is a misunderstanding that the ancients collectively referred to these five animals as "five poisons", because geckos are non-toxic, but they are considered highly toxic. Just like kudingchong is non-toxic, but it is considered highly toxic.

Spider is not one of the "five poisons", which is a false statement in Jin Yong's novels about the use of poison by believers of the "five poisons". If the questioner is unclear, I will list all kinds of "five poisons" as follows: 1, five poisons: bile, cinnabar, realgar, thorn stone and fish stone; 2. Five kinds of torture: flogging, whipping, burning, beating with a badge and licking; 3. Five kinds of poisonous insects: scorpion, snake, bee, cockroach and centipede-more common in the "symbol of five poisons", green snake, centipede, scorpion, gecko and toad-people often say this; Five social evils: cheating, gambling, gangs, smoking and prostitution. What people usually call whoring is included in prostitution.
