When a species is classified as threatened, it means that that particular species is expected to become endangered, not extinct. The species that are threatened, are species that have experienced a significant drop in numbers in recent times, but still have enough individuals to be able to survive and keep the species going. But if the situation starts to become worse and the species continues to lose numbers, than the species will fall into the category of endangered species, which will mean that it is expected that the species will die out in the very near future.
