Venomous fish do not necessarily cause poisoning if they are eaten, as the digestive system often destroys the venom. [1] There are at least 1200 species of venomous fish, [2] [3] with catfishes alone possibly contributing 250–625 species to that total. [4] The former number accounts for two-thirds of the venomous vertebrate population. [5]

An invasive species' "serious impact on biological diversity and/or human activities," and; That species' "illustration of important issues surrounding biological invasion". [1] According to the ISSG, "only one species from each genus was selected." [1] However, the renaming of Clidemia hirta [3] now implies two Miconia species in the list.
The hooded pitohui.The neurotoxin homobatrachotoxin on the birds' skin and feathers causes numbness and tingling on contact..

Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 1245 vulnerable fish species. [1] Of all evaluated fish species, 8.1% are listed as vulnerable.

The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .
