Latest Cetaceans Stories
An ancient whale skull is revealing new information about the birthplace of humanity and the role that climate change played in human evolution, researchers from the University of Potsdam in Germany and colleagues from Kenya and the US report in a new study.
Once they undergo menopause and their reproductive cycles come to an end, older female killer whales help lead the rest of their pod and direct them to the best food sources, a new study finds.
The bottlenose dolphin only colonized the Mediterranean after the last Ice Age -- about 18,000 years ago -- according to new research.
Scientists that track grey whale migrations along the western coast of North America are always looking for more efficient ways to track their subjects and a new set of thermal imaging cameras could help them do just that.
Be quiet in the ocean; whales can hear you. Scientists have discovered that baleen whales can hear through their very bones, and this discovery could be a massive help in whale conservation efforts.
Whale sharks, the biggest fish in the ocean, now are protected by NOAA and, if netted, must be released unharmed.
By measuring hormone in tissues comprised from keratin, researchers from the New England Aquarium in Boston and North Slope Borough in Alaska are hoping to find a way to study the physiological condition and reproductive activity of bowhead whales.
Killer whale biologists believe that at least one orca acted as a midwife during the recent birth of a calf. The birth of the calf was confirmed by Ken Balcomb of the Center for Whale Research.
The decade long study found that humpback whales do indeed use these “tick-tock” pulse noises when they hunt in groups at night in the almost total darkness of deep water.
At almost 100 feet in length, blue whales are believed to be the largest animals that ever existed, bigger even than any known dinosaur. And yet, scientists now tell us, there is room in the southeastern Pacific Ocean for two different kinds of blue whales, with two distinct populations living in the waters of the region.
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...
