Shark's loo stop caught on camera

It's as thick as your arm, smells revolting and now it's been caught on camera for what's thought to be the first time ever. What is it? Shark poo!

Biologists were so excited about spotting the whale shark going to the loo, they even scooped the poop out of the water so they could keep it!

But it's not as grim as it sounds - by testing the poo they can find out loads more about the giant creatures.

Despite being the world's biggest fish, very little's known about whale sharks...[BBC]
