The remains of the 9-foot great white shark were found on a beach four months after it was tagged by researchers.
They were shocked when they checked the information the tag provided.
According to The Australia News Network, data shows the shark was quickly taken to a depth of nearly 2,000 feet and had a fast increase in body temperature.
The explanation was that the animal was in the digestive system of a much larger creature.
“When I was first told about the data that came back from the tag that was on the shark, I was absolutely blown away,” filmmaker Dave Riggs said in an upcoming Smithsonian documentary, Hunt for the Super Predator.
But don’t be too worried about some new sea monster. Scientists believe the smaller shark was snatched up by a "colossal cannibal great white shark."
Researchers believe the bigger fish weighed more than two tons and topped 16 feet long.
