GAINESVILLE, FL—Upending the conventional theory that the animals are different species, a study conducted by marine biologists at the University of Florida confirmed Thursday that sharks are just really angry dolphins. “An exhaustive five-year-long field study combined with comprehensive DNA analysis proves that sharks are actually dolphins that are super fucking pissed,” said lead researcher Dr. Karen Delgado, noting that the reason sharks were considered solitary animals was because they were simply livid dolphins who needed to go off by themselves for a while to simmer down. “Once a dolphin becomes furious, it undergoes a number of physiological changes including growing several rows of jagged teeth, sprouting gills, and developing a layer of skin that seals up the blowhole. In rare cases, a dolphin can become so enraged that its head will morph into a flat, hammer-like shape. Eventually, the mammal calms down and rejoins the pod after its dolphin-like features return.” Delgado added that her team’s study comes in the wake of a similar discovery that walruses are profoundly wise sea lions.

Dolphins and war? That seems like an unfortunate pairing. But the U.S. Navy has been training the gregarious sea creatures to spot sea mines since the 1960s. Are they good at it?

But questions remain about what the animals are actually communicating
