Venomous fish are species of fish which produce strong mixtures of toxins harmful to humans (called venom) which they deliberately deliver by means of a bite, sting, or stab, resulting in an envenomation. As a contrast, poisonous fish also produce a strong toxin, but they do not bite, sting, or stab to deliver the toxin, instead being poisonous to eat because the human digestive system does not destroy the toxin they contain in their bodies. Venomous fish do not necessarily cause poisoning if they are eaten, as the digestive system often destroys the venom.

  • Als Giftfische werden Fische bezeichnet, die Toxine produzieren oder anreichern (sequestrieren). Giftige Fische finden sich sowohl unter den Knorpelfischen als auch unter den Knochenfischen. Die Anzahl der giftigen Fischarten wird auf 1200 geschätzt, das sind wesentlich mehr als die Giftschlangenarten. Es werden aktiv giftige Fische und passiv giftige Fische unterschieden. * Die aktiv giftigen Fische benutzen die von ihnen produzierten Toxine zur Abwehr von Feinden oder zum Nahrungserwerb. Das Gift kann durch Zähne oder Stacheln aktiv übertragen werden. Aktiv giftige Knorpelfische finden sich bei den Seekatzen (Chimaeriformes), den Stierkopfhaien (Heterodontus) und den Stechrochenartigen (Myliobatiformes). Bei den Echten Knochenfischen (Teleostei) verfügen Arten der Froschfische (Batrachoididae), die Arten der Skorpionfische (Scorpaenidae), die Petermännchen (Trachinidae), Himmelsgucker (Uranoscopidae) und die Kaninchenfische (Siganidae) über Giftstacheln, die Säbelzahnschleimfische (Nemophini) besitzen Giftzähne. * Passiv giftige Fische produzieren Toxine in bestimmten Organen oder reichern die von anderen Organismen produzierten Giftstoffe über die Nahrungskette in ihrem Körper an. Beim Verzehr können diese Substanzen zu Fischvergiftungen führen. Zu den passiv giftigen Fischen gehören Seifenbarsche (Grammistini), Kugelfische (Tetraodontidae), Igelfische (Diodontidae) und Kofferfische (Ostraciidae). In der Literatur finden sich auch die Bezeichnungen Giftfische für Fische, die einen Giftapparat zur Erzeugung beziehungsweise Einverleibung von Giften besitzen, und giftige Fische, deren Genuss gesundheitsgefährdend sein kann.

  • Venomous fish are species of fish which produce strong mixtures of toxins harmful to humans (called venom) which they deliberately deliver by means of a bite, sting, or stab, resulting in an envenomation. As a contrast, poisonous fish also produce a strong toxin, but they do not bite, sting, or stab to deliver the toxin, instead being poisonous to eat because the human digestive system does not destroy the toxin they contain in their bodies. Venomous fish do not necessarily cause poisoning if they are eaten, as the digestive system often destroys the venom. There are at least 1200 species of venomous fish, with catfishes alone possibly contributing 250–625 species to that total. The former number accounts for two-thirds of the venomous vertebrate population. There are more venomous fish than venomous snakes and indeed more than the combined total of all other venomous vertebrates. Venomous fish are found in almost all habitats around the world, but mostly in tropical waters. Encounters with these species injure over 50,000 people every year. Venomous fishes carry their venom in venom glands and use various delivery systems, such as spines or sharp fins, barbs, spikes and fangs. The most common venom delivery system is via dorsal spines. Venomous fish tend to be either very visible, using flamboyant colors to discourage predators from attacking them, or skillfully camouflaged and possibly buried in the sand. Apart from the value of improved self defense or capacity to kill prey, venom helps bottom dwelling fish by killing bacteria that could otherwise invade their skin. Few of these venoms have been studied. They are a yet-to-be tapped resource for bioprospecting to find drugs with medical uses. (en)
