A combination of the biology of marine mammals, mechanical vibrations and acoustics has led to a breakthrough discovery allowing scientists to better understand the potential harmful effects of sound on marine mammals such as whales and dolphins.
Illusive mammals such as the beaked whale are hardly seen, mysterious, and obscure, and yet they have become the focus of new studies due to the harm that military sonar systems seem to cause them.
Researchers from San Diego State University and the University of California have been using computer models to mimic the effects of underwater noise on an unusual whale species and have discovered a new pathway for sound entering the head and ears.
Blainville’s beaked whale (Mesoplodon densirostris), also known as the dense-beaked whale, can be found in a large range that includes the warm and tropical waters of all oceans. It prefers to reside at depths between 1,600 and 3,000 feet and does not migrate. This species received its common name from Blainville, the man who classified it as Delphinus densirostris after studying a description of a piece of one individual’s nose located in the Paris Museum. In 1846, John Edward Gray...
Taxonomy Cuvier first described Risso's Dolphin in 1812. The species' common name is for Mr. Risso who described a specimen to Cuvier on which Cuvier made his first description. Another common name for Risso's Dolphin is the Grampus (also the species genus) - although as a common name was historically used to describe the Orca. Population and distribution It is found worldwide in temperate and tropical waters, usually in deep waters rather than close to land. As well as the tropical...
