More than 50,000 swimmers are bitten by poisonous fishes every year leading to serious injuries and fatalities. Which are the world’s most dangerous fishes? Which fishes are the most poisonous?

  1. The Lionfish – These are various species of fishes belonging to the family scorpaenidae. They are very colorful and have long and separated spines instead of fishes. They are widely referred to as scorpion fishes, or turkey fish.                                
  2. Pufferfish – Known as Fugu is Japanese and variously referred to as baloonfish, blowfish or bubble fish, the pufferfish are some of the most poisonous fishes today. They have four large teeth fused into an upper and lower plate, thin hidden spines and feed on crustaceans and mollusks.
  3. Stonefishes – They are highly venomous and dangerous to humans. They produce powerful neurotoxins that from their dorsal fin spines when threatened. They look like stones making it very easy for swimmers and divers to step upon them.
  4. Stargazers – They are a family of marine fish that have eyes on top of their heads. They are mainly found in shallow waters and often burry themselves in sand from where they leap to ambush any prey that may pass by. They have poisonous spines and can also produce electric shocks.
  5. Toadfish – They are ray finned fish that appear like toads. The males have a swim bladder that can ‘sing’ in order to attract potential mates. They do not have scales, have large heads and with eyes set higher.

    I like fish-eating them that is. I guess these fish won’t be on my plate any time soon. They serve blowfish in Japan, but it is expensive.

    Some natives in our country also eat the puffer fish despite the poison. I wouldn’t dare do that as I still want to live a long fruitful life :-) This is a very entertaining and informative article on poisonous fishes. I think the stone fish is so unappealing.

    very interesting post.
    Ya, just the look only, look dangerous enough.
    The best is, when not sure, don’t eat them, or don’t touch them.

    Great article. Can you believe people in some Oriental countries eat pufferfish? I wrote an article a long time ago about how chefs who cook pufferfish have to undergo years of training and they have to prepare it in the exact way or they can poison someone. THe chef could spend 100 years studying, I’m not eating it. These chefs are the only ones who can cook it.

    Interesting topic. I think stonefishes may have the greatest opportunity to kill people. They really look like a rock.
