Nearly 60 pilot whales have died after becoming stranded on a beach in northern New Zealand, conservation authorities reported Friday.There were 73 total whales discovered on the beach mid-morning and the Department of Conservation's Carolyn Smith said the whales most likely beached overnight, which is why so many died before rescue operations were launched.Of the 73 pilot whales, 15 have survived, but are reported to be in "poor condition." Volunteers are making another attempt to rescue the...

Finless porpoises may be more endangered than previously thought. A new study of finless porpoises, a rare type of toothed whale, found that there are two species, not one, and they rarely intermingle. Scientists say that finless porpoises living in the fresh waters of China's Yangtze river are genetically unique, numbering fewer than 1000.  They warn that greater efforts must be made to prevent these animals. The whales inhabit a wide range of tropical and temperate waters...

Scientists are now saying that marine mammals are not only smarter than previously thought, but many also share several attributes once claimed to be exclusively human. Cetaceans, an order of more than 80 whales, dolphins and porpoises, have the ability to express self-awareness, suffering and have social cultures with high mental abilities, say marine biologists. If the notion is true that whales are intelligent and sentient beings, it would threaten to destroy the assumption that they are...

A study released on Wednesday reveals that Southern Ocean sperm whales' feces are an unexpected ally in the fight against global warming. The cetaceans have been previously fingered as climate culprits because they breathe out carbon dioxide (CO2), the commonest greenhouse gas. However, according to the paper published in the British journal Proceedings of the Royal Society B, this is only part of the picture. Australian biologists estimated that the 12,000 sperm whales left in the Southern...

A new finding raises the possibility that commercial whaling may have taken a role breaking apart social groups of whales. Dr. Christian Ramp and colleagues of the Mingan Island Cetacean Study group based in St. Lambert, Canada have been studying whales since 1997 in the Gulf of St. Lawrence. The scientists are recording the movements of baleen whales including blue, fin, minke and humpback whales, adding to a set of data that stretch back 30 years. The team found that individual female...

Whales are remarkably diverse, with 84 living species of dramatically different sizes and more than 400 other species that have gone extinct, including some that lived partly on land. Why are there so many whale species, with so much diversity in body size? To answer that, UCLA evolutionary biologists and a colleague used molecular and computational techniques to look back 35 million years, when the ancestor of all living whales appeared, to analyze the evolutionary tempo of modern whale...

Dolphins, whales and porpoises have extraordinarily small balance organs, and scientists have long wondered why. Now a study at Washington University School of Medicine in St. Louis has contradicted a leading theory, which held that the animals moved their heads so vigorously that they had to have smaller, less responsive balance organs to avoid overwhelming their senses. Working with a Midwestern zoo and a local rancher, the researchers, led by Timothy E. Hullar, MD, a Washington University...

A new paper by researchers at George Mason University and the University of Otago in New Zealand shows a strong link between the diversity of organisms at the bottom of the food chain and the diversity of mammals at the top. Mark D. Uhen, a geologist at Mason, says that throughout the last 30 million years, changes in the diversity of whale species living at any given time period correlates with the evolution and diversification of diatoms, tiny, abundant algae that live in the ocean. In the...

Cetology
2013-10-02 11:21:29

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...

Indo-Pacific Bottlenose Dolphin, Tursiops aduncus
2013-09-19 11:24:25

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
2013-08-29 10:15:35

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
2013-08-17 13:31:16

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...

Hourglass Dolphin, Lagenorhynchus cruciger
2013-08-16 10:45:47

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...
