Latest Beaked whale Stories
Researchers have always believed that Chilean devil rays (Mobula tarapacana) mostly lived near the ocean's surface because they are most often observed gliding through shallow, warm waters.
Scientists monitored Cuvier's beaked whales' record-breaking dives to depths of nearly two miles below the ocean surface and some dives lasted for over two hours.
Researchers say they have discovered a new species of beaked whale after studying several stranded cetaceans on remote tropical islands in the Indian and Pacific Oceans. The first of these new species was discovered more than 50 years ago.
In December, the National Marine Fisheries Service authorized Navy sonar training exercises off the coasts of Hawaii and California through 2018. This authorization came despite admittance by the Navy that the work will kill up to 155 marine mammals and harm numerous others.
Researchers from Duke University in Durham, North Carolina, have observed the behavior of whales as they come into areas where sonar is being used and found whales may even avoid venturing into new feeding areas when they hear sonar.
Perhaps one of the greatest things about science is that there’s still so much left to discover. Though scientists have been studying and cataloguing the world for hundreds of years, there are still creatures and mysteries which continue to elude us.
Scientists know that the blood and tissues of some deceased beaked whales stranded near naval sonar exercises are riddled with bubbles.
In a recent study to be published on April 27, 2011, in the peer-reviewed open-access journal PLoS ONE, Dr. Elliott Hazen and colleagues found that oceanographic and prey measurements can be used to identify beaked whale foraging habitat.
Scientists have long been aware of a link between naval sonar exercises and unusual mass strandings of beaked whales.
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.
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...
Sowerby's Beaked Whale (Mesoplodon bidens), also known as the North Atlantic/North Sea Beaked Whale, was the first beaked whale to be described. Its name, bidens, derives from the two teeth present in the jaw, now known to be a very common feature among the family. It is altogether a rather typical representative of the genus. Physical description Sowerby's Beaked Whale has a typical body shape for the genus, and is mainly distinguished by the male's dual teeth that are found very far...
