Scientists have discovered a new type of lion roar — the intermediate roar — which is shorter and lower-pitched than the animal's iconic, full-throated roar.
The researchers found that these intermediate roars always follow full-throated roars. The discovery reveals that lion vocalizations are more complex than previously thought, said study lead author Jonathan Growcott, a doctoral student in mathematics and statistics at the University of Exeter in the U.K.
