Without beds or sofas in the ocean, how exactly do whales take naps? As it turns out, they do so with a very strange sleeping position.
Switzerland-based photographer Franco Banfi was following a pod of sperm whales in the waters near Dominica Island when the massive creatures suddenly just stopped and did a synchronised vertical rest. Basically, they sleep ‘standing up’ – or ‘swimming up’, rather.
The peculiar behaviour was first documented in 2008, after British and Japanese researchers stumbled upon a similar pod in rest. After tagging and studying the whales, they learned that these power naps occur for approximately seven percent of the whale’s life, in short intervals of just 6-24 minutes.
