Scientists used underwater drones to find out when sperm whales like to eat

Underwater robots that glide through the sea have revealed a pet peeve of Mediterranean sperm whales: early morning breakfasts. A research team led by the University of East Anglia discovered the dining preference by equipping the droids with acoustic monitoring devices that recorded the ‘click’ sounds made by the animals. Sperm whales produce a wide variety of these noises. They emit the sounds to communicate with their buddies and for echolocation, which helps them work out where things are by listening to the echoes. The researchers focused on the powerful and highly directional clicks the whales produce while foraging. When in a foraging…
