    Some animals' sounds appear similar to those emitted by other species; other species are easy to identify because of their profoundly different sounds. Listening systems limited to frequencies audible to humans, or even smaller ranges, like in many military systems, can detect only a small fraction of the possible sounds emitted by marine mammals. Dolphins communicate using compression waves (longitudinal waves). Some of the sounds dolphins make are outside the range of human hearing. Upon spotting a hungry shark, dolphin A sends a message to dolphin B. To send this message as effectively as possible, dolphin A would Question options. back dolphins (Sousa chinensis) (Jefferson & Karczmarski, ). Colouration is known to change between birth and adulthood in some odontocetes—for example, beluga whales (Delphinapterusleucas) (Brodie, ), Indo-Pacific humpback dolphins (Jefferson & Karczmarski, ), and Atlantic spotted dolphins (Stenella frontalis) (Perrin et al., ).

In order to understand the lives of Atlantic spotted and bottlenose dolphins through a non-invasive long-term study, “In Their World, on Their Terms”, the Wild Dolphin Project (WDP) has been researching the same pod of Atlantic spotted dolphins, Stenella frontalis, in the Bahamas for over 23 years.

Dolphins can hear and produce not only low-frequency sounds below 20 kHz, which humans can also hear and produce, but go a step further to high-frequency sounds of up to kHz, which are too high for humans to hear. Not only can dolphins produce tonal sounds like humans, they're capable of vocalizing at a variety of frequencies simultaneously.

It also features unique underwater echo location sounds. Underwater sound production occurs in aquatic mammals, including cetaceans (whales, including dolphins and porpoises).

While most aquatic mammals use the vocal folds of the larynx for generating sounds (including the infrasonic vocalizations of baleen whales), ultrasonic vocalization (USV) occurs only in odontocetes (toothed whales).Cited by: 1.

Some sounds are continu-ous, such as the sounds from ships, dredging, drilling, oper-ating wind and tidal turbines, and some naval sonar systems. These sounds may be tonal, or they may include a wide range of frequencies. Some may be ‘rougher’ than others, with a high crest factor.
