Shark experts startled to find great white sharks wash ashore missing livers, hearts

Three dead great white sharks washed ashore in South Africa last week and they all had one curious thing in common - their bodies were intact, but missing vital organs like livers and hearts.

While that kind of precision removal of organs sounds like something only surgeon could accomplish, shark experts believe that killer whales are the culprit.

From LiveScience.com:

In a strange case of extremely picky eating, orcas off the coast of South Africa are killing great white sharks, but the killer whales are chowing down only on the sharks' livers and, in some cases, their hearts, researchers say.

Although orcas aren't known to regularly hunt great white sharks, "it's not unprecedented," said Andrew Nosal, an assistant professor of biological sciences at Saint Katherine College in San Marcos, California, and a visiting assistant researcher at Scripps Institution of Oceanography in San Diego.
