Latest Cetacea Stories
Scientists have made a fascinating discovery in the northern Indian Ocean: humpback whales inhabiting the Arabian Sea are the most genetically distinct humpback whales in the world and may be the most isolated whale population on earth.
After thousands of orca sitings off the coasts of Spain, Portugal and Morocco, scientists have finally identified where the whales are hunting for red tuna.
In recent weeks, humpback whales have been spotted in Tulemar Resort's bay area in Manuel Antonio, Costa Rica, during their annual migration period. Manuel
The unusual river dolphins, some of them known for their poor eyesight and side-swimming behavior are all descendants of ocean-dwelling species. Until now, however, there has been no consensus about their relationships, and few specimens to help illuminate them.
New study turns a long-accepted evolutionary assumption on its head, finding that whale pelvic bones play a key role in mating.
The time delay between dolphins and whales receiving a reward and their squeals is the same as the delay between a pleasant experience and dopamine release – suggesting that dolphins and whales experience pleasure.
Scientists examining a taxonomically confused group of marine mammals have officially named a species new to science: the Australian humpback dolphin, Sousa sahulensis
Whales have often been viewed at the lonely nomads of the seas, but a new report has found that whales are actually great engineers of marine ecosystems.
The ocean is an increasingly industrialized space. Shipping, fishing, and recreational vessels, oil and gas exploration and other human activities all increase noise levels in the ocean and make it more difficult for marine mammals to hear and potentially diminish their range of hearing.
Researchers from Yale University have announced the discovery of a new species of ancient porpoise with a massive underbite.
Cetology is a branch of marine mammal science that studies about eighty species of dolphins, whales, and porpoise, all of which are classified within the Cetacea order. Cetologists, who practice cetology, work to understand the distribution, development, behavior, and other aspects of cetaceans. The study of cetaceans began in the Classical era. About 2,300 years ago, Aristotle documented details about some cetacean species, calling them mammals, while traveling on the Aegean Sea with...
The Indo-Pacific bottlenose dolphin (Tursiops aduncus) is one of three recognized species of bottlenose dolphin that can be found in the waters near southern Australia, South China, and India. Its range also includes the Red Sea and the eastern coastal areas of Africa. All bottlenose dolphins were classified as one species, the common bottlenose dolphin or T. truncates, until 1998 when the Indo-Pacific bottlenose dolphin was found to be distinct. This species is distinct from other bottlenose...
Dall’s porpoise (Phocoenoides dalliz) can only be found in the North Pacific, with a range that includes the Sea of Japan and the Okhotsk and Bering Seas. This range extends to southern California in the east and to the southern waters of Japan in the west. When normal weather patterns change and waters become colder, this species can be found in in Baja, California, specifically in Scammon's Lagoon, and strays can occasionally be found in the Chukchi Sea. It prefers to reside in cold...
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...
The hourglass dolphin (Lagenorhynchus cruciger) is a rare species that can be found in Antarctic and subAntarctic waters. Most sightings of this species have been made in the southern waters near the Shetland Islands, off the coast of Tierra del Fuego, Argentina, and in the southern waters near New Zealand. It is thought that this dolphin does not congregate in large numbers in any area of its circumpolar range. Qouy and Galmard first recognized the hourglass dolphin as a new species in...
