EL Between sounds and silences: Communication and echolocation in cetaceans

Abstract

Cetaceans are a group of mammals adapted to marine aquatic life, with a highly developed sense of hearing that allows them to communicate and interact with their environment at high frequencies in dolphins and low frequencies in whales. Echolocation is an ability of dolphins, which allows them to locate objects such as rocks and other individuals, as well as prey through the emission of vibrations or high frequency pulses that bounce off the target, a prey, for example, and return as an echo, which is picked up by the emitter. This form of communication also allows the study of cetaceans in a non-invasive and sustainable way.
