Dropping terms: Endangered species

VULNERABLE SPECIES - A species particularly at risk because of low or declining numbers or small range, but not a threatened species.

threatened species – a species whose population is not yet low enough to be in immediate danger of extinction, but who certainly faces serious problems. If the problems affecting these species aren’t resolved, it is probable that the species will become endangered. The eastern indigo snake and the red kangaroo are examples of threatened species.

endangered species – a specie, plant or animal, that is in immediate danger of becoming extinct. Its numbers are usually low, and it needs protection in order to survive. The Siberian tiger, the southern sea otter, the snow leopard, the green pitcher plant, and thousands of other plants and animals are endangered worldwide.

extinct species – an extinct species is one that is no longer living. The passenger pigeon, the dodo, and the Stegosaurus are examples of extinct species. These animals no longer exist on the earth.
