Swimming next to a 10 meter Whaleshark

As the largest fish in the sea, reaching lengths of 12 meter or more, whale sharks have an enormous menu from which to choose. Their favorite meal is plankton and krill. They scoop these tiny animals up, along with any small fish that happen to be around, with their colossal gaping mouths while swimming close to the water's surface.
The whale shark, like the world's second largest fish, the basking shark, is a filter feeder. In order to eat, the beast juts out its formidably sized jaws and passively filters everything in its path. The mechanism is called “cross-flow filtration”, similar as baleen whales.
Preferring warm waters, whale sharks populate all tropical seas. They are known to migrate every spring to the continental shelf of the central west coast of Australia. The coral spawning of the area's Ningaloo Reef provides them with an abundant supply of plankton.
Although massive, whale sharks are docile fish and sometimes allow swimmers to hitch a ride.
