 The Culebra Island giant anole is the only anole considered possibly extinct in recent history (other extinct anoles are prehistoric and only known from fossil remains that are millions of years old).Locals reported sighting of the Culebra Island giant anole as recent as the 1980s, but this likely involved misidentifications of young green iguanas.Others, at least the Morne Constant anole, do not grow as large today as they once did.
