Extant

From Freepedia

Extant means "still existing". It is the opposite of extinct, and can be applied to species, cultures and works of culture (e.g. plays, poems) that are currently still in existence.

In biology, the expression is commonly used in discussions of living and fossil species. For example, of the group of molluscs known as the cephalopods, there are approximately 600 extant and 7500 extinct species (Barnes, 1987).
