Sperm Whales blow bubbles to achieve restful, vertical sleep
Sperm Whales blow bubbles to achieve restful, vertical sleep Friday 24 July 2026 New research from the University of St Andrews and Université de Neuchâtel, has uncovered the mechanism which allows sperm whales to sleep in a unique vertical position, just under the ocean surface. Sperm whales are the only whale known to rest vertically. It’s thought to enable them to sleep effectively by buffering them from surface wave action, while avoiding the energy needed to dive to deeper depths.

Sperm whales are the only whale known to rest vertically.
