Human acoustic tools can distinguish individual whales by analyzing micro-characteristics of their vocalizations, and the whales can probably do the same. This does not prove that the whales deliberately use some vocalizations to signal individual identity in the manner of the signature whistles that bottlenose dolphins use as individual labels.
For example, a blue whale can communicate with another blue whale using sound over thousands of miles across the sea. [6] While terrestrial animals often have a uniform method of producing and detecting sounds, aquatic animals have a range of mechanisms to produce and detect both vocal and non-vocal sounds. [7]
Denise L. Herzing is the founder and Research Director of the Wild Dolphin Project, [1] a non-profit which funds the study of the natural behaviors and communication of Atlantic spotted dolphins in the wild. [2] Herzing has earned her Ph. D. in Behavioral Biology/Environmental Studies, her M. A. in Behavioral Biology, and her B. S. in Marine ...
Baleen whales - a group that includes the blue whale, the largest animal in Earth's history - use a larynx, or voice box, anatomically modified to enable underwater vocalization, researchers said ...
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 ...
Research has recently shown that beaked and blue whales are sensitive to mid-frequency active sonar and move rapidly away from the source of the sonar, a response that disrupts their feeding and can cause mass strandings. [2] Some marine animals, such as whales and dolphins, use echolocation or "biosonar" systems to locate predators and prey.
Whale watchers got quite a show recently when one playful dolphin decided to show off for them in Monterey Bay, California. ABC News shared a clip on Sunday, March 24th of the whale watchers ...
For those who can’t make it out, a free app “Dolphin Count” allows for real-time dolphin spotting. The network maps the data quarterly and shares it to the nonprofit’s website. To report a ...
