An Endling is the last known member of a species or subspecies. The endling’s death means the end of the species as a whole. The word was supposedly coined by
Robert Webster in the mid 1990s. The term is used, however, it still does not have an entry in The Merriam-Webster Dictionary despite Robert trying to get it into the dictionary before his death in 2004. The endling for the Thylacine was called Benjamin.
