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 ...
Kuczaj (2006) used an underwater keyboard, which humans and dolphins can touch to signal an action. [45] Amundin et al. (2008) had dolphins point narrow echolocation beams onto an array of hydrophones which acted like a touchscreen to communicate with the researchers [46] Reiss (2011) used an underwater keyboard which dolphins could press.

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]
Bowhead whales are highly vocal [21] and use low frequency (<1000 Hz) sounds to communicate while travelling, feeding, and socialising. Intense calls for communication and navigation are produced especially during migration season. During breeding season, bowheads make long, complex, variable songs for mating calls. [22]

Different species of aquatic animals can sometimes communicate.
