Not all humans are morning people. Neither, according to a new study, are all sperm whales – at least when it comes to foraging for food.

The research, led by the University of East Anglia (UEA), has revealed the daily habits of the endangered Mediterranean sperm whale. Unmanned underwater gliders equipped with acoustic monitors recorded the sperm whale sounds, or ‘clicks’, over several months and 1000s of kilometres of ocean.

Sperm whales are highly vocal, producing distinct types of clicks for both echolocation and social interaction purposes. The study, published today in the Endangered Species Research, focused on the extremely powerful and highly directional ‘usual clicks’ produced while foraging. MORE
