| The
Giant Tortoises of the Galapagos Islands are probably their most
famous inhabitants. Originally there were fifteen different sub-species,
each being native to a particular island or, in the case of Isabela,
a particular volcano. There are now eleven - four have become extinct
due to humankind's hunting them for food, oil and scientific specimens.
This one was photographed at Galapaguera, on San
Cristobal island, which is one of the few places where you can
see giant tortoises in a completely natural environment. Because
there is quite a lot of low vegetation on San Cristobal, the tortoise
has a dome-shaped shell. Where the vegetation grows higher up, tortoises
have a saddleback-shaped shell so that they can lift their heads
higher to get at the leaves.
