What is the minimum number of animals that are required for an animal to not be endangered?

There are many species of animals that are now endangered and they become a part of an endangered list of animals. This happens because they were hunted, died of disease or died at a faster rate than those being born in that species. When this happens, there is such a low number of that animal that they become endangered.

Some animals become endangered because they lose their habitat. An animal may become endangered because at least fifty percent of the population has died over the span of ten years. After that takes place, there are some rules and laws that will protect these endangered animals. Otherwise, these animals will become extinct which means that there will be no animals of that type left on Earth.

There are seven categories endangered animals—starting with the least concern, going all the way to extinct. Animals that are of least concern have a widespread and abundant population while extinct animals do not exist any longer. There is also a distinction between endangered species and critically endangered, the latter creeping closer to extinction.

If an animal species has a population of less than 2,500 mature individuals, it qualifies as endangered. This means that if not carefully watched or if carelessly managed, these animals have a 20% chance of dying out in the next 20 years. If an animal has less than 250 mature individuals, the status goes to critically endangered. This means that the probability of the species surviving goes to about a 50% chance of extinction in the next 10 years.
