A new finding raises the possibility that commercial whaling may have taken a role breaking apart social groups of whales. Dr. Christian Ramp and colleagues of the Mingan Island Cetacean Study group based in St. Lambert, Canada have been studying whales since 1997 in the Gulf of St. Lawrence. The scientists are recording the movements of baleen whales including blue, fin, minke and humpback whales, adding to a set of data that stretch back 30 years. The team found that individual female...

Whales are remarkably diverse, with 84 living species of dramatically different sizes and more than 400 other species that have gone extinct, including some that lived partly on land. Why are there so many whale species, with so much diversity in body size? To answer that, UCLA evolutionary biologists and a colleague used molecular and computational techniques to look back 35 million years, when the ancestor of all living whales appeared, to analyze the evolutionary tempo of modern whale...

Experts from the National Oceanic and Atmospheric Administration (NOAA) have discovered genetic evidence that there are multiple species of killer whales. Lead researcher Phillip Morin and his colleagues at the NOAA's Southwest Fisheries Science Center in La Jolla, California, took tissue samples from 139 orcas from the North Atlantic, the North Pacific, and Antarctica. By analyzing the mitochondria of each, they confirmed the existence at least three distinct killer whale species. According...

New technology in gene sequencing supports empirical evidence of multiple species In a report published today in the journal Genome Research, scientists report finding strong genetic evidence supporting the theory there are several species of killer whales (Orcinus orca, also known as orcas) throughout the world's oceans. Scientists have suspected for some time that there was more than one species of killer whales because of differences in behavior, feeding preferences and subtle physical...

Scientists are now saying that there are actually two types of killer whales living in UK waters instead of just one, as was previously thought, according to BBC News. The whales are different from each other in both the way they look and the way they eat, and the males of one type are about 6-feet longer than the other. Researchers believe the killer whales could be at an early stage of becoming two separate species. The findings have been published by the international group of...

Conservation success depends on understanding feeding behavior Scientists in Scotland, Canada and the US have proposed a new method to identify priority areas for whale conservation. The team's findings, published in Animal Conservation, suggest that even small protected areas, identified through feeding behavior, can benefit highly mobile marine predators such as killer whales. "There are enormous challenges associated with setting conservation priorities for such mobile and migratory...

ORLANDO, Fla., Nov. 12 /PRNewswire/ -- WHAT: Last week, an innovative new parenting book, "Whale Done Parenting" was released nationwide. Written by veteran SeaWorld killer whale trainer Chuck Tompkins and the world's bestselling business author, Ken Blanchard, "Whale Done Parenting" is based on the positive relationship philosophy of animal training that SeaWorld pioneered. Chuck is a skilled trainer, dynamic speaker and loving father of two boys whom he raised using these...

Federal officials say they are considering giving killer whales in Washington state's Puget Sound a broader protective zone. Boats are now required to stay 100 yards away from the whales. The proposed National Marine Fisheries Service regulations would double that and would also close off a half-mile channel off San Juan Island between May and September, The Seattle Times reports. The rules would apply to whale-watching boats and recreational boaters but not to commercial fishermen, cargo...

New research from scientists in Russia shows that even killer whales like to socialize, creating and visiting social clubs just like humans do. Until now, scientists never knew why up to 100 killer whales would meet in the Avacha Gulf off the coast of Russia, forming huge superpods despite the fact  they typically live in smaller groups.  But after studying the whales, the researchers discovered that these groups act as clubs in which the fish-eating killer whales (Orcinus orca)...

A killer whale at the Miami Seaquarium should be released into the wild rather than forced to live in a concrete tank, animal activists say. Shelby Proie, one of the more than 30 activists seeking to free Lolita the killer whale, said during a protest Saturday at the Miami tourist site that the 7,000-pound animal does not deserve to be penned in an aquarium. Every week one of us goes in to check on her, the 24-year-old Nova Southeastern University student told the South Florida Sun-Sentinel....

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...

Dall’s Porpoise, Phocoenoides dalliz
2013-08-29 10:15:35

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...

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...

Ross Seal, Ommatophoca rossii
2013-01-01 15:44:30

The Ross seal (Ommatophoca rossii) is a true seal in the Phocidae family, and can only be found on pack ice in Antarctica. This species was formally described by James Clark Ross in 1841, during his British Antarctic Expedition. It is very uncommon to see in its range and rarely leaves the pack ice, with stray individuals occurring off southeast Australia or sub-Antarctic islands. The Ross seal can reach an average length between 5.5 and 6.9 feet, although some females can reach up to 8.2...

Crabeater Seal, Lobodon carcinophagus
2012-06-26 14:40:11

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...
