What ate this great white shark’s tag?

The Smithsonian Channel recently added this video to its YouTube channel, which documents a 3m (10′) female white that was tagged as part of program tracking white sharks (Carcharodon carcharias) along Australia’s coast. Four months after the shark was tagged, it’s tracking tag was recovered along a beach.

At one point in the data revealed a sudden decrease in depth down the continental shelf to a depth 580m (1,900′). The depth changed was followed by a significant increase in temperature from 46°F to 78°F (8°C to 26°C), which explained by the tag having been ingested (presumably with a portion of or all of the shark) by another predator. The data revealed that the temperature remained at the elevated level for 8 days.
