Do sperm whales ever sleep? This is a common question, but it’s one that people ask quite often. This is because we now have photos of how these ocean giants nap.

Franco Banfi, a professional underwater photographer, was the one who took the photo of the rare photograph while following a group of sperm whales near Dominica Island in the Caribbean Sea.

The animals stopped moving suddenly and entered synchronized vertical rest. This behaviour was first observed in 2008 by biologists from Japan and the UK. They drifted into a group of completely still sperm whales. Further studies revealed that the collective nap lasts approximately 7 percent of a whale’s lifetime and occurs in very short intervals of 6-24 minutes.
