A new report warns that levels of noise in the world's oceans are causing serious problems for whales, dolphins and other marine mammals. Undersea noise blocks animals' communication and disrupts feeding, according to the International Fund for Animal Welfare (Ifaw). Some say naval sonar has been linked to the mass deaths of some cetaceans. The level of ocean noise in some regions is doubling each decade and Ifaw says protective measures are failing. "Humanity is literally drowning out marine...

Although once under threat of extinction, many big whales are on the "road to recovery" thanks to bans set in place in the 1980s, an environmental group said Tuesday. In its review of cetaceans, the International Union for Conservation of Nature (IUCN) reported a "guardedly optimistic" picture for many large whales, according to Randall Reeves, chair of the cetacean specialist group of the IUCN. "Humpbacks and southern right whales are making a comeback in much of their range mainly because...

Four weeks on from the shocking incident that led to the death of 26 dolphins near Falmouth, research released Monday sheds new light on the extent of the problems facing Cornwall's marine mammals. A study by the University of Exeter and Cornwall Wildlife Trust, published in the journal Biodiversity and Conservation, has revealed a disturbing rise in the number of whales, dolphins and porpoises found dead on Cornish beaches. The frequency of these mammals, collectively known as cetaceans,...

Under the sea, predatory pilot whales take part in high-speed chases as they track down their prey.The cetaceans have been observed reaching such high speeds that scientists have likened their hunting technique to that of the cheetah, according to researchers in the Journal of Animal Ecology.Their findings may dispel the common notion of whales as large slow creatures.The research is the first to document the remarkable "burst-speed" of the pilot whale."As far as we know, no other whale has...

Britain's Defence Science and Technology Laboratory (DSTL) believes a device it developed to guide warships through mine fields may also have applications in reducing the estimated 300,000 small whales and dolphins caught in fishing nets each year. Although originally designed to mark underwater locations such as channels that have been cleared of explosives, developers of the new believe a smaller version could be fitted to fishing nets to reduce numbers of cetaceans (whales, dolphins and...

WASHINGTON -- It sounds like a stretch, but a new study suggests that the missing evolutionary link between whales and land animals is an odd raccoon-sized animal that looks like a long-tailed deer without antlers. Or an overgrown long-legged rat. The creature is called Indohyus, and recently dug up fossils reveal some crucial evolutionary similarities between it and water-dwelling cetaceans, such as whales, dolphins and porpoises. For years, the hippo has been the leading candidate for 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...

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...
