Question: what is the most dangerous fish out there?

Alex Seeney answered on 12 Jun 2018:

It depends on what sort of danger you mean. Sharks can be dangerous to us because of their size and power, but attacks on humans are mostly mistaken identity. The puffer fish can be poisonous if certain parts of it are eaten, and that can be fatal to us. There are also some highly venomous fish, such as the stonefish, which can seriously hurt us if step on their venomous spines.
