Swordfish are killing sharks on a regular basis, apparently - BGR

Over a half dozen sharks have now been found dead on shorelines in the Mediterranean, all with evidence of conflict with a swordfish.

Unlike the fate suffered by the thresher shark, most of the sharks found with swordfish wounds were stabbed in or near the head.

But why would the swordfish be attacking sharks, which aren’t their prey, and flipping the food chain upside down.

The researchers note that the sharks being stabbed are traditional the same species that tend to feed on young swordfish, suggesting that the larger adult fish are stabbing and killing the sharks as a defense to their young.

It’s also possible that the swordfish are engaging with sharks in order to expand their territory and ensure a plentiful supply of food remains available for them and their kin.
