Latest Cetacea Stories
The theory that all animal life emerged from the sea has been well covered, but much less is known about the creatures that went back. Whales, dolphins, seals and sea turtles are examples of marine tetrapods--an exceptional group of animals that moved from the sea to the land and back again.
When research biologist Brittany Hancock-Hanser came upon the scene of a killer whale attack, the only thing she found left of the victim was a heart, some lungs and a bunch of oil. It was a classic case of "Who Bit the Dust?"
Be quiet in the ocean; whales can hear you. Scientists have discovered that baleen whales can hear through their very bones, and this discovery could be a massive help in whale conservation efforts.
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
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...
