The Charles Darwin Foundation has compiled a checklist of all marine and terrestrial species known from the Galapagos Islands. You'll find six species of Geospiza, four of Sula, fifteen of Geochelone (including Geochelone darwini), and five of Darwinothamnus among many others. If you don't recognize those genera (and even if you do), head on over to the Darwin Foundation site and have a look.

It is great to know that the Darwin Foundation has compiled a checklist of marine and land animals.
The Galapagos Islands are the most incredible living museum of evolutionary changes, with a huge variety of exotic species (birds, land animals, plants) and landscapes not seen anywhere else.
