However, the 2007 Guinness World Records program rated the Brazilian wandering spider (Phoneutria) as the most poisonous spider in the world. People also call them banana spiders because they often live on banana leaves. While other spiders spin webs to trap their prey, banana spiders hunt on the ground, searching for and attacking their prey directly. They are usually active at night and are very aggressive. Their venom is a very strong nerve poison, paralyzing the respiratory organs, causing suffocation and death. In addition, their venom can make men impotent.

When the devil-faced fish’s dorsal fin rays pierce the victim’s flesh, the toxin will directly affect the human motor system, nervous system and smooth muscle system of the heart. However, if prepared properly, devil-faced fish will be a favorite dish of many people with its crispy, sweet taste, helping blood circulation well, reducing the risk of heart disease and stroke.
