An endling is an individual that is the last of its species or subspecies. Once the endling dies, the species becomes extinct. The word was coined in correspondence in the scientific journal Nature. Alternative names put forth for the last individual of its kind include ender and terminarch. The word relict may also be used but usually refers to a group that is the last of the species.
