Santa Fe is home to one endemic species and one endemic subspecies:
the Barrington Land Iguana (Conolophus pallidus) and the Santa Fe
Rice Rat (Aegialomys galapagoensis bauri)
------------Sorry, no picture - Rats!
This may be hard to believe but I have seen it with my own eyes.
Land Iguanas when disturbed tend to jerk their heads from up to down, like they are nodding, all except on Santa Fe.
As I said this sub-species of land Iguana jerks its head just the opposite from down to up. (so if you ever come arcoss a land Iguana in the Wal-Mart parking lot, for example, and he is jerking his head from down to up, you can say to your friend "That Land Iguana came from Santa Fe Island in the Galapagos."
I am sure your shopping friend will be very impressed! (That's right before she climbs up you back sreaming; "Lis...Lis..Lizard.....BIG LIZARD"
Santa Fe Island, Galapagos
