Deep Dreamers


Today we learned that sperm whales sleep with their bodies in a vertical position. Swiss wildlife photographer Franco Banfi (previously featured here) captured this awesome photo, entitled ”Synchronized Sleepers”, showing a pod of sperm whales asleep together in the brilliant blue depths off the coast of Dominica Island.

Sperm whales only sleep for short periods of 6-24 minutes, so witnessing this, let alone being able to capture it on camera, is incredibly rare.

In 2008 a team of researchers suggest that, unlike other cetaceans, sperm whales (Physeter macrocephalus), Vulnerable (IUCN)appear to enter short, but periodic, bouts of sleep throughout the day — an observation that Kaplan says could hint that sperm-whales are actually “the least sleep-dependent mammals known.”

“Synchronized Sleepers” was a finalist in the Human/Nature category of the 2017 Big Picture Competition.
