The Galapagos Islands are volcanoes which rose from the ocean floor far from any land mass. Wildlife arrived by flying, floating or swimming. Land-based predators simply couldn't make the trip. The lack of natural predators explains the extremely tame nature of most Galapagos wildlife. Isolation also accounts for the relatively small number of species found in the islands, many of which are endemic, a fact not lost on Charles Darwin.
The following photos were taken throughout the trip and hopefully provide a reasonably comprehensive overview of the wildlife we were privileged to see.
