Extant is a term commonly used to refer to
taxa (such as
species,
genera or
families) that are still in existence (living). The term
extant contrasts with
extinct. For example,
Brandt's Cormorant is an extant species, while the
Spectacled Cormorant is an extinct species. Likewise, of the group of
molluscs known as the
cephalopods, there are approximately 600 extant species and 7500 extinct species.
