Secret of the appearance of octagonal figures on the seabed revealed

Scientists have discovered mysterious octagonal ‘stamps’ on the bottom of the Fram Strait. Investigations using remotely piloted vehicles revealed that the mysterious footprints were left by Dumbo octopuses as they fed.

These creatures inhabit the deep waters of all the Earth’s oceans, but remain little known. Their diet consists mainly of worms and crustaceans and their feeding strategy is similar to that of the holothurians.
