Latest Cetaceans Stories
Blasting sound waves through the ocean to the seafloor in search of fossil fuels may do more harm than good, according to environmentalists. But the US Department of Interior has been considering giving large oil and gas companies permission to do just that.
Conservation scientists say the endangered Huemul deer, native to Patagonia, is bouncing back from the brink of extinction.
A new study by researchers from researchers at the Woods Hole Oceanographic Institute (WHOI) and Aarhus University in Denmark is focusing on one of the most endangered animal species currently known: the river dolphin.
According to new research published in the journal Naturwissenschaften, the dwarf baleen whale lived well into the Ice Age.
Researchers have identified areas off southern California with high numbers of whales and assessed their risk from potentially deadly collisions with commercial ship traffic in a study released today in the scientific journal Conservation Biology.
A beach in southern Chile is being overwhelmed by millions of stranded prawns that have taken up two miles worth of the coastline.
Marine biologists reported they have discovered a whale skeleton sitting on the ocean floor near Antarctica for the first time.
A new study of mass whale strandings has shown that despite previous theories, family ties do not appear to play a role in this bizarre phenomenon. The true cause, however, remains a mystery.
A biologist has found that whales' baleen systems actually works best by entangling food as water flows across them, according to a report in The Journal of Experimental Biology.
Traveling into uncharted territory in search of food can be a dangerous undertaking, but some bottlenose dolphins may benefit by moving through their habitat with relatives who may be more experienced or knowledgeable.
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 North Atlantic right whale (Eubalaena glacialis), also known as the black right whale or the northern right whale, is one of three right whales in the Eubalaena genus. It can be found in a small population of about 396 individuals in the western North Atlantic. If it does occur in the eastern North Atlantic, experts assert that it only numbers in the tens, making it nearly extinct in that area. This species migrates into the western North Atlantic to feed in the spring, summer, and fall...
The southern right whale (Eubalaena australis) is a species of baleen whale that can be found in different regions in the summer and winter seasons. During the summer, it can be found in the Southern Ocean, possibly near Antarctica. During the winter, populations disperse into many warmer areas to breed, including waters near Chile, Argentina, New Zealand, South Africa, Peru, Namibia, Brazil, Australia, and Madagascar, among other areas. Right whales were first classified by Carolus...

Credit: OpenCage/Wikipedia (CC BY-SA 2.5) The pygmy killer whale is widely distributed in tropical and sub-tropical waters worldwide. Regular sightings of this species occur off the coast of Hawaii and Japan, and also in the Indian Ocean near Sri Lanka and Lesser Antilles. In the Atlantic the pygmy killer whale has been seen off the coast of South Carolina and Senegal. This species swims in...
The crabeater seal (Lobodon carcinophagus) is a true seal that can be found around the whole of Antarctica. Its range also includes small areas in South America, New Zealand, Africa, and Australia. It resides on the pack ice zone for the entire year, even as it shifts seasonally, and prefers to stay in the continental shelf area in water with a depth of less than 1,968 feet. Because the populations are so wide spread and are sufficiently mixed, there have been no subspecies found. Because...
