Cone Snails, also known as Cone Shells, were named after their shape that resembled a cone. Just on the coast of China, there were already more than 70 different types of cone snails that were widely distributed. Although they weren't as famous as the Blue-Ringed Octopus or the Portuguese Man O' War, the hidden, poisonous creature did not inflict any less harm to humans each year when compared to them.
The Blue-Ringed Octopus and the Portuguese Man O' War were mollusks with tentacles, and since they looked really disgusting, most people would not take the initiative to touch them. But the shell of a Cone Snail was really beautiful and they looked like a delicate piece of artwork lying on the beach, so people couldn't help but want to pick it up.
The content of the Cone Snail's venom was very complicated, and each type of cone snail had a different kind of venom, so there was no specific detoxification serum.
