Extinct means there are none of that species in the wild, threatened means the number of that species is declining, and endangered means there are only a few thousand of that species in the wild.
endangered species
an endangered species
This is referred to as being "critically endangered," a classification used by conservation organizations to denote a high risk of extinction for a species. It signifies that the population is extremely low and facing severe threats to its survival.
The official list shows 1030 species, but it is likely higher than that. It is really difficult to say accurately, because there are a number if designations, in order of increasing threat; threatened, vulnerable, endangered, critically endangered, extinct in the wild, etc.
Presently there are 38 known species of mammals that are extinct. However, of them there are some that are kept in captivity with scientists trying to save them from going extinct. With global warming becoming a major issue, the fact is the existing 28,270 animal species of mammals are threatened by the harms done to the planet. 6,524 vertebrate-species were listed as threatened, in the year 2006. In the same year - 2006 - 2,101 invertebrate-species were listed to be threatened. In 2006, 253 fish-species were listed as critically endangered. In 2006, 442 amphibian-species were listed as critically endangered. 81 species of animals are considered extinct or critically endangered, as well as endangered or vulnerable. The number of animal listed in the U.S.A., is 935. There are over 1,000 animal species that are endangered at varied levels, across the world.

There are 8 species of rattlesnakes in the United States that are listed as either a "species for concern," "threatened," or are a "candidate" for listing on the U.S. Fish & Wildlife Services Species Reports. However, there are no rattlesnakes listed as endangered at this time.
The average number of endangered species varies significantly by region and taxonomic group. Globally, the International Union for Conservation of Nature (IUCN) Red List categorizes thousands of species as endangered, with estimates often indicating that around 15,000 species are currently threatened with extinction. The average can fluctuate based on conservation efforts, habitat loss, climate change, and other factors influencing biodiversity. Thus, the average number of endangered species is a dynamic figure that reflects ongoing ecological changes.
Yes, they are listed on the major endangered species lists, but not under the specific status of Endangered yet. They are currently listed on the US Fish and Wildlife Service endangered list as a "Threatened" species, and on the IUCN Red list as "Vulnerable," which is a subcategory of the IUCN Threatened status. If their numbers keep growing, and our understanding of them increases, they may be removed from the lists of animals in danger. When animal species are "removed from the lists", they are put under a status of "delisted". Their population has been improving, and they currently number over 20K in the wild, and could be over 25K.
