It's suspected that the seal dragged the octopus up from the bottom of the ocean, before battling it out at the surface.
It's not the first time a Kaikoura Kayaks group has spotted such a battle, either. Owner Matt Foy said they'd come across battles before, with some lasting up to 20 minutes.

Foy said it wasn't the nicest way to go, with pieces of octopus sometimes landing in the nearby kayaks.
