A Wednesday necropsy, led by Massachusetts Division of Marine Fisheries scientist Greg Skomal, found no signs of the shark being hooked, either, and uncovered no definitive signs of trauma. As such, its results were inconclusive, the Atlantic White Shark Conservancy says in a Facebook post.

A necropsy was underway Wednesday to determine the animal's cause of death, according to the Atlantic White Shark Conservancy.

A great white shark that washed ashore at a Cape Cod beach earlier this week is named Koala, and was known to local researchers, investigators said. Its cause of death is still a mystery, as a necropsy was inconclusive.
