The term that accurately describes a species likely to become endangered is "threatened species." This classification encompasses organisms that are at risk of extinction in the near future due to a variety of factors, including habitat loss, environmental changes, or human activity.

Vulnerable species are those that are not currently endangered but have a higher than usual risk of becoming so. This is similar to but not the same as being classified as a threatened species. A rare species may be uncommon, but it does not necessarily indicate an imminent risk of extinction since rarity does not always correlate directly with endangerment. In contrast, common species are abundant and therefore not at risk of becoming endangered. Thus, the distinction lies in the specific status and urgency of the threat faced by the species.
