The ocean floor is full of strange shapes, scars, and formations, but few have puzzled scientists quite like the mysterious holes found in seafloor sediment. Some appeared in neat rows deep in the Atlantic, while others formed crater-like pits across the North Sea. At first glance, some looked almost artificial, while others were thought to be caused by methane gas escaping from beneath the seabed.
The latest research suggests that at least some of these holes have a surprisingly natural explanation: marine animals. In the North Sea, scientists linked tens of thousands of shallow pits to porpoises hunting sand eels buried in the sediment, showing how animal behavior can physically reshape the seafloor. But not every ocean-hole mystery is fully solved, which makes the story even more fascinating.
