Chuck Bednar for redOrbit.com - Your Universe Online California blue whales have become the first group of the endangered species to experience a population rebound, demonstrating their ability to rebound when carefully managed, according to new research appearing in the journal Marine Mammal Science. Blue whales are the largest animals on Earth, reaching nearly 100 feet in length and weighing nearly 200 tons when they reach adulthood. They are also the heaviest creature to ever live,...

The Company of Biologists Dolphins and whales squeal with delight Sam Ridgway has spent most of his life learning about dolphins and whales. Over his five-decade career he has asked these cetaceans various questions, including how deep they can dive and how depth affects their hearing. As he trained each animal to answer his questions, he rewarded them with tasty fish treats, and each time that they received a reward he remembers that they squealed. Initially he thought that the squeals...

The Company of Biologists First live observations of minke whales feeding under sea ice Highly maneuverable and built like torpedoes, minke whales are the most common whales in Antarctic waters, yet the animals could be living on a knife edge as their sea-ice homes dwindle rapidly. 'Sea ice in the area around the Antarctic Peninsula has decreased dramatically in the last 30 years', warns Ari Friedlaender from Oregon State University, USA, adding, 'yet we do not know how critical the sea...

April Flowers for redOrbit.com - Your Universe Online Whales have been endangered by human activity for hundreds of years mainly due to commercial hunting and fishing concerns. A new study from Oregon State University, published in PLOS ONE, reveals that these are not the only human-derived challenges whales face. Blue whales, in particular, are also at an increased risk of injury and death from shipping traffic. The research team, led by OSU Marine Mammal Institute researcher Ladd...

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...

North Atlantic Right Whale, Eubalaena glacialis
2013-08-26 11:17:56

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...

Southern Right Whale, Eubalaena australis

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...

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...
