What is the difference between a Vulnerable species, threatened species and endangered species?

Endangered = likely to become extinct if nothing is done to protect them

Threatened = not yet endangered, but could be if the status quo continues

Vulnerable = not threatened or endangered but could be headed that way

Threatened species: Any species which are vulnerable to becoming endangered in the near future.

Endangered species: A population of organisms which is at risk of becoming extinct because it is few in numbers or threatened by a changing environment.

Vulnerable Species: A species which has been categorised by the International Union for Conservation of Nature (IUCN) as likely to become Endangered.

The difference is how long they are going to survive before they become extinct.

Vulnerable species: A specie that cannot take care of them selfs and are likely to become exstinct.

Threatened species: a specie that are about to be put on the endangered list.

Endangered: A species that are on the verge of extinction.

The difference is the Likelyness of extinction.
