A photographer went up close to a pod of giant sperm whales and captured incredible photos of the animals asleep in a vertical pose, a rare sight.
Professional underwater photographer Franco Banfi is the man who managed to capture these extremely rare and beautiful photographs as he followed a pack of sperm whales in the Caribbean Sea near the Dominica Island.
He stated that the whales suddenly stopped moving and all moved into a synchronised vertical rest. This cult-like behaviour was only first documented back in 2008 when a team of biologists from the United Kingdom and Japan drifted into a group of completely still sperm whales.
After further studies, they found that the sperm whale’s group slumber sessions occur for approximately 7% of a whale’s whole life in very short intervals of just 6-24 minutes.
Here is a video of the sleeping whales.
