Giant whale shark captured looming beneath a boat full of unsuspecting tourists in breathtaking photograph

The extraordinary image was taken by Tom Cannon, 26, earlier this week off the coast of Western Australia and captures the gaping abyss of the whale shark's giant mouth.
Tom said: "The animal in the picture is what is called a whale shark and is the largest fish on the planet.
"It spends most of its time living mysteriously at depths unreachable by humans but from March until July they can be seen of the back of the Ningaloo Reef In Coral Bay and Exmouth, Australia.
"The picture was taken about 6km off shore on the back of the Ningaloo Reef Coral Bay while on tour with Ningaloo Reef Dive and Snorkel.
"I wasn't scared, we swim with these guys quite a lot and people come from across the world to see them.
"They are a very docile fish and will often shy away from anything they feel threatened by.
"This particular shark was really curious and spent the entire 50 minutes on the surface with us chasing bubbles and checking everybody out.
"This was a rare experience to have such a curious playful shark. They usually swim in straight lines in search of food.
"That is one of the commercial boats that my company Ocean Collective Media take photos on board of.
"It charters tours to see whale sharks during the season and Manta Rays year round.
"The people on board were customers and staff members who were quite amazed to see the whale shark behaving this way.
"The creature isn't dangerous. We are their biggest threat with the increasing pollution to our oceans they need our help!
"I am co-founder of a underwater photography company called Ocean Collective Media with my friend Sam Lawrence."
The whale shark - the largest known extant fish species, capable of growing to lengths of 12 metres (40 feet) - is also classed as "Endangered" on the Red List of Threatened Species compiled by the International Union for Conservation of Nature (IUCN).
