The Basking Shark is one of a few species that lives in temperate latitudes, both north and south of the equator, but not between these two zones in the tropics.
Whale sharks are most often seen on diving trips in open water near Darwin and Wolf islands. Galapagos sharks are small, up to 2 metres, and narrow, with colours ranging from brown to grey. They are carnivores, even preying on other sharks, and can swim down to depths of 100 metres.
