They are large whales with echolocation capabilities, they have a remarkable ability to identify and locate objects using ultrasound. In addition to a sound reminiscent of a trumpet, the rest of the vocalizations consist of a repetition of simple clicks, which can, however, vary greatly in frequency and also in the pattern and rhythm of the repetition. These sounds travel a distance of 10 km through the water.

Jumping out of the water and hitting the surface with the fins can also be a form of communication, although its true meaning has yet to be unraveled. They feed at great depths, both during the day and at night, being able to remain submerged for up to 2 hours and descend to 3,200 meters. It occurs in all oceans, generally in waters with depths greater than 200 m, being only absent from regions closer to the polar caps. It is protected by the Berne Convention - Annex II, CITES - Annex I and Habitats Directive - Annex IV and is considered vulnerable by the IUCN.
