Scientists are now saying that there are actually two types of killer whales living in UK waters instead of just one, as was previously thought, according to BBC News. The whales are different from each other in both the way they look and the way they eat, and the males of one type are about 6-feet longer than the other. Researchers believe the killer whales could be at an early stage of becoming two separate species. The findings have been published by the international group of...

Paper focuses on new tools to listen to sounds in the ocean Over the past decade, researchers have developed a variety of reliable real-time and archival instruments to study sounds made or heard by marine mammals and fish. These new sensors are now being used in research, management, and conservation projects around the world, with some very important practical results. Among them is improved monitoring of endangered North Atlantic right whales in an effort to reduce ship strikes, a leading...

In 2006, a team of Spanish and American researchers found the fossil remains of a whale, 4.5 million years old, in Bonares, Huelva. Now they have published, for the first time, the results of the decay and fossilization process that started with the death of the young cetacean, possibly a baleen whale from the Mysticeti group. This is not the first discovery of the partial fossil remains of a whale from the Lower Pliocene (five million years ago) in the Huelva Sands sedimentary formation, but...

When the ancestors of living cetaceans"”whales, dolphins and porpoises"”first dipped their toes into water, a series of evolutionary changes were sparked that ultimately nestled these swimming mammals into the larger hoofed animal group. But what happened first, a change from a plant-based diet to a carnivorous diet, or the loss of their ability to walk? A new paper published this week in PLoS One resolves this debate using a massive data set of the morphology, behavior, and...

Two recent sightings of porpoises in the Baltic Sea thrilled biologists since the marine mammals were thought extinct in the region, a Swedish researcher says. Anna Roos, a researcher at the Swedish Museum of National History, said the two porpoise sightings off Sweden's west coast occurred in a span of less than 10 days, offering encouraging news about the animals' population in the Baltic, The Local reported Saturday. To get two reports from the central Baltic in such a short space of time...

We can only marvel at the way that dolphins, whales and porpoises scythe through water. Their finlike flippers seem perfectly adapted for maximum aquatic agility. However, no one had ever analysed how the animals' flippers interact with water; the hydrodynamic lift that they generate, the drag that they experience or their hydrodynamic efficiency. Laurens Howle and Paul Weber from Duke University teamed up with Mark Murray from the United States Naval Academy and Frank Fish from West Chester...

A national park established to protect groups of dolphins and whales - recently discovered mingling and feeding off East Timor - may soon be funded by the young Asian country's own government, AFP reported. However, some foreign assistance will be required to preserve the area and develop eco-tourism in one of the few places in the world with such a wide variety of large sea mammals, officials said. Officials in Dili said aerial surveys of the hotspot from scientists at the Australian...

Mexico's swine flu crisis, coupled with its reeling economy, may end a plan to save the world's most endangered cetacean. The vaquita, the world's smallest cetacean, has seen its population dwindle to 150, and nearly 30 more die each year due to fishing nets. Mexican officials have cut funding aimed to make fishing boats vaquita-friendly. The endangered cetacean illustrates the problem with other dolphins and porpoises around the world, say campaigners. Currently, scientists,...

Small whales are disappearing from the world's oceans and waterways as they fall victim to fishing gear, pollution, and habitat loss "“ compounded by a lack of conservation measures such as those developed for great whales, according to a new WWF report. "Small Cetaceans: The Forgotten Whales," released yesterday, states that inadequate conservation measures are pushing small cetaceans "“ such as dolphins, porpoises and small whales "“ toward extinction as their survival is...

Experts say a minke whale that was likely injured by floating rope has provided a unique insight into the dangers posed to marine animals by fishing gear, BBC News reported. The large whale was spotted off the coast of Quebec, Canada, with a huge scar around its throat and feeding in a way never before recorded for minke whales, probably in response to its injury. It is one of the first sightings to detail the handicaps that can be caused to animals that become entangled in fishing nets and...

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

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...
