Something's Been Making Weird Pits in the Seafloor

The video explores mysterious pits on the ocean floor near Germany, initially thought to be caused by methane. Researchers found these pits were not conical, as expected for methane, but flat, suggesting a different cause. Investigations pointed to porpoises digging for sand eels as the likely cause, marking the first time marine megafauna have been observed influencing the sea floor on such a scale. This discovery could help differentiate between pits caused by marine life and those indicating tectonic activity, aiding in earthquake monitoring.
