Marine Biologists Finally Know What Hunts Bull Sharks In California — And It Makes No Sense

Bull sharks have been showing up dead off the Southern California coast — with wounds that don't match any known predator in these waters. When a dive captain hands over a carcass and a researcher stumbles onto a pattern buried in years of tracking data, the investigation rules out the obvious suspects one by one. What's left is a predator nobody saw coming — smaller, older, and far from the top of anyone's danger list, now exhibiting behavior never before confirmed at this scale. The evidence is still circumstantial, but it's forcing marine biologists to rethink everything they assumed about who really rules these waters.
