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.
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 ...
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 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 ...
Bioacoustic Research Program at the Cornell Lab of Ornithology distributes a number of different free bioacoustics synthesis & analysis programs. Macaulay Library at the Cornell Lab of Ornithology is the world's largest collection of animal sounds and associated video. Xeno-canto A collection of bird vocalizations from around the world.
Just off the coast of Dana Point in Southern California, visitors and marine enthusiasts watched as the mammals took over the ocean. In the video published by Storyful on Dec. 26, a pod of around ...
The California sea lion is used in military applications by the U.S. Navy Marine Mammal Program, including detecting naval mines and enemy divers. In the Persian Gulf , the animals can swim behind divers approaching a US naval ship and attach a clamp with a rope to the diver's leg.
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.
