Diver Adam Malski filmed a battle between two great white sharks 50 kilometers off the coast of South Australia's Neptune Islands. The islands are a popular destination for tourists interested in great white sharks. The attacker was a 4.8 meter Carcharodon carcharias known as Gilbert. The unnamed smaller shark has not been seen since the fight, so Malski does not know if he survived.
The dramatic conflict might explain what happened to a 3-m great white whose electronic tag washed up on a beach with information revealing it spent eight days in the belly of a larger predator, suspected to have been a really large great white.
