Latest Cetaceans Stories
As the controversial Japanese whaling season quickly approaches and as the conservationist group Sea Shepherd launches its fleet of vessels to confront whalers head on, Australia announced it would send a plane as well to monitor the situation in the Southern Ocean.
A new genetic study shows there are five distinct humpback whale populations in the North Pacific Ocean.
Newly discovered evidence that killer whales can hunt marine mammals during the nighttime has led scientists to suggest that the creatures can use their hearing to help locate prey.
The National Oceanic and Atmospheric Administration announced unsettling and unfortunate news this week centered on the bottlenose dolphin and Cetacean populations on the east coast of the United States. We are witnessing the most unprecedented stranding and die-off of these creatures in our recorded history.
The most common and well-known of their kind, bottlenose dolphins are famous for their roles in movies, television and water parks everywhere. And to the layperson's eye, one bottlenose dolphin might not look any different from another. When you look closer, however, perhaps genetically, there are telltale differences in each individual.
Humpback whales have exhibited a complex set of feeding techniques, including "trapping" krill and other prey within bubble nets produced by the whales and gulping up to two-thirds their weight in prey-laden water.
A genomic study of the Yangtze River dolphin, commonly known as the Baiji, provides new insight into the genetic and evolutionary adaptations of dolphins and valuable resources for the conservation of mammals, and particularly, of cetaceans.
Scientists have discovered a previously unknown species of humpback dolphin swimming off the coast of northern Australia.
What could a 50 ton whale and a one gram bat have in common? They share a success story - both have developed the ability to use echolocation, a type of biological sonar, for hunting.
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...
