Listening to endangered Amazon river dolphins

The pink river dolphin and the tucuxi are two species of freshwater dolphins in danger of extinction that inhabit inaccessible areas of the Amazon. They are echolocating animals, which use sound as a form of navigation. Echolocation clicks can be used to track their movements and contribute to conservation strategies for their natural habitat. This is demonstrated by a study published in Scientific Reports featuring researchers from the UPC’s Laboratory of Applied Bioacoustics (LAB).
