Critically Endangered. Example: Amur leopard, around 35-50 in the wild.
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.
You know a species is becoming extinct when its population is decreasing rapidly. The decrease could be caused by human involvement, natural disasters, change of climate, hunting, etc., etc.
Endangered Species are ones that have a very small population and that population is at a greater risk of becoming extinct. Many species that become extinct never make to the endangered species list. Extinct Species are ones that are either known (documented) to be extinct or are so few in population that a recovery is considered highly unlikely even under excellent conditions.
because of pollution and bulk hunting
Extinct is already dead and Endangered is there is less of them left in the world meaning we should try to save them !!
if a species is declining then the species that eats that one has less food and will decline fast as well
This animal is endangered, but not yet in imminent danger of extinction, with a population of at least 10,000, maybe 29,000 or more. The species is declining in some areas.
The fish population is declining due to overfishing, habitat destruction, and pollution. Conservation efforts and sustainable fishing practices are needed to help stabilize and increase fish populations.
extinct species
The definition of Extinct is no living individuals of a species or a non-viable reproductive population of a species of animals. If the species has no ability to reproduce it is extinct even though there are living examples.
No, there are still 4 species of tapir left in the wild which live in Mexico and south America and have an estimated collective population of 7,000+ individuals. 3 of the 4 species are Endangered according to the IUCN red list of threatened species and one is Vulnerable. This is due to the declining trend in population numbers globally.
The killer whale as a species is not an endangered species, although there are a couple of declining local populations. But the species as a whole is doing fairly well.
