A 4m (13′) white shark (Carcharodon carcharias) that was found washed ashore in Western Australia had apparently died as the result of choking on a sea lion, according to Sky News. The 4m shark had no initial visible signs of injury or disease, according to the report. However, further examination revealed a sea lion lodged in the shark’s throat.

The shark was filmed off Coronation Beach by YouTube user CadMonkey two days before it washed ashore. As can be seen in the video, the shark appears to be in distress. Research scientist Rory McAuley told Sky News that the shark might have been trying to dislodge the obstruction.
