Most endangered animal
Lonesome George
Ecuador (Abingdon Island)

The Abingdon Island giant tortoise Geochelone elephantopus abingdoni is represented by a single living specimen, an aged male called `Lonesome George', making it the world's rarest reptile. With little hope of discovering another specimen, this particular subspecies of Galapagos giant tortoise is effectively extinct while still alive, unless cloning techniques can generate future replicas of George.

Lonesome George also holds the record for the rarest reptile.
