Because all marine mammals have excellent underwater hearing, transients probably remain silent until they have caught their prey to avoid detection by acoustically sensitive animals. For the same reason, the mammal-eating orcas tend to restrict their echolocation, occasionally using just a single click (called a cryptic click) rather than the ...
Marine biologist Philip Clapham describes the song as "probably the most complex in the animal kingdom." [11] Male humpback whales perform these vocalizations often during the mating season, and so it was initially believed the purpose of songs is to aid mate selection. [12] However, no evidence was found that links these songs to reprosexuality.
Aquatic animals use mechanoreceptors to detect acoustic signals. Aside from aquatic mammals which have external ears, other aquatic vertebrates have ear holes containing mechanoreceptors. [7] Aquatic invertebrates such as lobster, crabs and shrimps have external sensory hairs and internal statocysts as their sound-detecting organs. [11] [12]
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...

Toothed whales (Odontocetes) pass air through a system of air sacs and muscular phonic lips, which vibrate to produce audible vocalizations, thus serving the function of vocal folds in other mammals. [4] Sound vibrations are conveyed to an organ in the head called the melon, which can be changed in shape to control and direct vocalizations. [5]
The vocalizations produced by the bearded seal are very unique, possibly because their trachea is different from that of other Northern Pacific phocids. A majority of the rings in the trachea are incomplete with only a membrane attaching the two ends. [24] Sample of underwater bearded seal vocalizations taken using a hydrophone
Human–animal communication is the communication observed between humans and other animals, ranging from non-verbal cues and vocalizations to the use of language. [ 1 ] Some human–animal communication may be observed in casual circumstances, such as the interactions between pets and their owners, which can reflect a form of spoken, while not ...
