Process in a dolphin echolocation: in green the sounds generated by the dolphin, in red from the fish. Idealized dolphin head showing the regions involved in sound production. This image was redrawn from Cranford (2000). Odontocetes produce rapid bursts of high-frequency clicks that are thought to be primarily for echolocation. Specialized ...
They can hear higher-pitched sounds than humans or most dogs, detecting frequencies from 55 Hz up to 79 kHz. [17] [18] Cats do not use this ability to hear ultrasound for communication but it is probably important in hunting, [19] since many species of rodents make ultrasonic calls. [20]

Porpoising occurs mainly when dolphins and porpoises are swimming at speeds greater than 4.6 m/s. [11] Here, jump length is roughly equal to distance traveled when the cetaceans are submerged. [11] This exposes the blowhole for longer which is needed to get enough oxygen to maintain metabolism and therefore high speeds over long periods of time.

Different species of aquatic animals can sometimes communicate.
