Guess which animals can outlive all others, based on the oldest confirmed individual(s).
Largely based on: https://en.wikipedia.org/wiki/List_of_longest-living_organisms.
Some animals have been grouped together and represented by the longest-living species, genus or order, due to the fact that they appear many times on the Wikipedia list.
Both the animal's/group's name or the name of its taxonomic rank (order, family etc) are accepted.
