Footage of the incredible moment an octopus bravely hunts down an extremely venomous stone fish off the coast of Egpyt.

The video, filmed by a diver in June this year, shows the large octopus chasing down the creature, apparently unconcerned by its lethal stings.

The filmer later wrote online: "Why does the stone fish not use its incredibly poisonous stings?

"Maybe the octopus is immune to this lethal predator or he is intelligent to a point that he knows how to catch the stone fish, avoiding the dangerous stings."
