2. List of whale vocalizations - Wikipedia

   en.wikipedia.org/wiki/List_of_whale_vocalizations

   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 ...

3. Whale vocalization - Wikipedia

   en.wikipedia.org/wiki/Whale_vocalization

   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.

4. Communication in aquatic animals - Wikipedia

   Amphibians like frogs and toads can vocalise using vibrating tissues in airflow. For example, frogs use vocal sacs and an air-recycling system to make sound, while pipid frogs use laryngeal muscles to produce an implosion of air and create clicking noise. [7] Aquatic mammals such as seals and otters can produce sound using the larynx.

5. Melon (cetacean) - Wikipedia

   en.wikipedia.org/wiki/Melon_(cetacean)

   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 ...

6. Bearded seal - Wikipedia

   en.wikipedia.org/wiki/Bearded_seal

   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

9. Toothed whale - Wikipedia

   en.wikipedia.org/wiki/Toothed_whale

   Toothed whales consist of some of the most widespread mammals, but some, as with the vaquita, are restricted to certain areas. Odontocetes feed largely on fish and squid, but a few, like the orca, feed on mammals, such as pinnipeds. Males typically mate with multiple females every year, making them polygynous. Females mate every two to three years.
