A white shark washed up dead near Geraldton, in western Australia, which died apparently because it had a sea lion stuck in its throat.

The shark appeared to be injured, but no one knew what it was really happening.

Dr. Rory McAuley, principal research scientist of the Department of Fisheries said that the shark had no visible signs of injury, but it appeared to have a large Australian sea lion stuck in its throat.

“Such a large object may have damaged the shark’s internal organs or impeded water flow into his gills, contributing to his death,” McAuley said.
