Mako shark does incredible backflip

This is the incredible moment a mako shark was caught on camera doing a back flip.

Jack Hatwell was on a fishing trip off the coast of Adelaide when a member of his party suddenly hooked the monster fish.

As they were trying to reel it in, it leapt out of the water, turned 360 degrees and then plunged back into the ocean.

"Finally, after another 15 minutes of reeling we ended up getting the shark on board the boat," Hatwell said.
