U.S. scientists say they have discovered marine mammals are being exposed to a cocktail of pesticides, as well as new contaminants. In what's called the most extensive study of pollutants in marine mammals' brains, Woods Hole Oceanographic Institute scientists found the animals are exposed pesticides such as DDT and PCBs, as well as contaminants such as brominated flame retardants. Eric Montie, lead author of the study, performed the research in collaboration with Mark Hahn and Chris Reddy of...

Researchers have reported witnessing adult tucuxi dolphins trying to kill a newborn calf of their own species in what is known as the first record of these dolphins attempting infanticide, BBC News reported.While it is often noted in various mammal species, infanticide is rarely recorded among cetaceans, the group of animals that includes whales and dolphins.Experts say the behavior has only been reported two other times in bottlenose dolphins, yet now they believe it may be much more common...

Researchers say global warming is bringing food stocks closer to shore, causing the mass beaching of whales along Australia's coast, the AFP reported.Last week, nearly 90 long-finned pilot whales and bottlenose dolphins were beached along the Hamelin Bay on Australia's west coast in the last month.Experts say it took the total number of beached cetaceans in southern Australia beyond 500 in the past four months alone, including a single stranding of almost 200 on King Island.The...

Scientists have uncovered two early whale fossils that may shed light on how these ancestors to modern whales evolved from walking on land to becoming sea dwellers. Experts say the fetal remains found along with the 47.5 million-year-old pregnant female fossil were positioned head down, suggesting these creatures gave birth on land, while spending much of the rest of their time in the water. Paleontologist Philip Gingerich, whose University of Michigan research team discovered the fossils in...

Local and Australian researchers said on Wednesday that one of the world's highest concentrations of dolphins and whales -- many of them protected species -- has been discovered off the coast of East Timor. A study by the Timor government uncovered a "hot spot" of marine cetaceans migrating through deep channels off the Timor coast, including blue and beaked whales, short-finned pilot whales, melon headed whales and six dolphin species. Principal scientist Karen Edyvane said the team was...

Research suggests that the bizarre teeth of male beaked whales have evolved to help females choose their mates. Apparently, the males use the two teeth on the outside of their jaws not for eating, but for scratching each other. DNA analysis shows the teeth probably evolved as secondary sexual traits to help females select males of the right species, scientists said. Beaked whales make up the least known group of whales or dolphins. They spend most of their time deep in the ocean foraging for...

WASHINGTON, Nov. 6 /PRNewswire/ -- The Institute of Cetacean Research (ICR), a Japanese scientific body that studies whales, today accused Animal Planet and Discovery Communications of deceiving their viewers in a new television series "Whale Wars", due to be broadcast in the United States starting tomorrow. Whale Wars purports to be a reality TV program, but instead it shows staged events directed by the Animal Planet filmmakers themselves, in a "tail wagging the dog" format. The...

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. "There's not much known about these creatures - where they live, their lifestyle," says Ted Cranford from San Diego State University. "In fact, they might be the least understood group of large mammals on Earth." This summer, the research yacht Song of the Whale, operated by the International...

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...
