A fish that cannot miss in the list of the 10 most dangerous fish: The popular blowfish. This fish has developed the ability to inflate to defend against predators, so it swims very slow and needs to consume a lot of food daily. It’s usually found in tropical and subtropical waters, but also in fresh and brackish waters; although today we are contributing to their disappearance, since the rivers where they live are increasingly contaminated and their food is becoming less and less. The blowfish also has thorns in its body to defend against other species, but that make it a dangerous fish for humans, because the thorns have a substance 1200 times more poisonous than cyanide, even capable of killing 30 people.
