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 ...
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.
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
Kookaburras are birds known for their interesting call, and I love listening to them. Tanganyika Wildlife Park caught their kookaburra laughing earlier this month, and it's the best sound you'll ...
The whale ear has specific adaptations to the marine environment. In humans, the middle ear works as an impedance equalizer between the outside air's low impedance and the cochlear fluid's high impedance. In whales, and other marine mammals, there is no great difference between the outer and inner environments.
