WATCH: Galapagos, realm of gentle and giant sharks

With its iconic giant tortoises, crested black iguanas, huge ocean manta rays and a veritable menagerie of other cool creatures, the Galapagos Islands are one of the most beautiful places you will probably never visit.

in order to protect the flora, fauna and ecosystems of this Pacific archipelago that inspired Charles Darwin's theory of evolution, Ecuador is in the odd position of having to turn away perhaps millions of would-be tourists each year.

Even sadder for the traveller is the fact that they're unlikely to ever swim alongside the giants in their underwater realm by these islands. These giants are whale sharks. It's the biggest shark - and the biggest fish - in the sea, often found roaming in warm waters around the globe with its huge mouth agape in search of dinner. they typically grow to be bigger than a double-decker bus: between 6 to 16 metres and more than 20 tonnes. 

The size and mysterious nature of these gentle giants are something to behold. If you can't do in in the Galapagos, at least you have the above video to take you inside the underwater realm of these giant sharks.
