Juvenile Predation Preventing Steller Sea Lion Recovery
2012-01-19 04:36:29

A new study suggests that the impact of predation on juvenile Steller sea lions in the Gulf of Alaska has been significantly underestimated, creating a “productivity pit” from which their population will have difficulty recovering without a reduction of predators. Scientists using “life history transmitters” to study Steller sea lions found evidence of age-structured predation by orcas (killer whales) and other large predators in Alaska´s Prince William Sound...

California Biologist Charged With Feeding Killer Whales
2012-01-06 13:39:44

A California marine biologist and whale-watching tour operator has been charged with violating a federal law that prohibits disturbing killer whales in the Monterey Bay National Marine Sanctuary. The Associated Press reports that on Wednesday, charges were brought against Nancy Black saying that she had violated the Marine Mammal Protection Act, which, among other things, makes it illegal to feed marine mammals such as dolphins, sea lions and whales. Ms. Black, who owns and operates...

New Zealand Beach Scene Of Orca-Shark Battle
2012-01-02 09:00:01

A spectacular display of nature´s sometimes cruel cycle of life was witnessed by beachgoers at Blue Cliffs Beach in Tuatapere, New Zealand when orcas, also known as killer whales, forced a group of large sharks to swim into shallow waters or risk being eaten. One shark desperate to escape from the enormous beasts even beached itself on the sand and was filmed desperately flapping around in a bid to escape the whales, which were unable to move onto the sand, reports Rick Dewbury for...

Beluga Whales Trapped By Ice In Russia
2011-12-18 06:04:23

More than a hundred Beluga whales are trapped in frigid water surrounded by ice floes in the Chukotka region of Russia´s Far East, and risk death unless they are rescued soon, local authorities said. The flock of gentle whales was trapped in the Sinyavinsky Strait off the Bering Sea near the village of Yanrakynnot, a statement from the Chukotka Autonomous Region said, with local governor Roman Kopin calling for the government to send an icebreaker to the region to try and free them...

Using Crowdsourcing To Understand Whales
2011-11-30 10:25:24

Whales have long been known to communicate through sound patterns, songs and calls. However there remains much mystery as to what these sounds mean and if whales have distinct dialects. Marine researchers, in an attempt to learn what the communications might mean, must sift through fifteen-thousand hours of recordings to better understand the dialogue among these sea mammals and so have created the Whale Song Project (aka Whale FM), a whale-song identification project that Scientific...

When both a predator and its prey are conservationally at risk, it can be difficult to find the right balance of ecosystem management to sustain and protect both. Such is the case for a particular population of orcas called southern resident killer whales and their prey, Chinook salmon, off the coast of Washington State and British Columbia, but a new detailed model of the two species may provide some guidance about what must be done to conserve both. The study, reported in the Nov. 9...

Antarctic Killer Whales Seek Spa-like Relief In The Tropics
2011-10-27 04:43:23

NOAA researchers offer a novel explanation for why a type of Antarctic killer whale performs a rapid migration to warmer tropical waters in a paper published this month in the science journal Biology Letters. One tagged Antarctic killer whale monitored by satellite traveled over 5,000 miles to visit the warm waters off southern Brazil before returning immediately to Antarctica just 42 days later. This was the first long distance migration ever reported for killer whales. "The whales are...

Tracking their dinner may be the best way to help North Atlantic right whales in Cape Cod Bay avoid being hit by recreational and commercial boats, according to a team of researchers who studied the whales for two years. "Auto-detection buoys are making a remarkable attempt at recording the whale sounds to show when whales are in the area," said Susan Parks, assistant professor of acoustics and ecology and senior research associate, Penn State Applied Research Laboratory. "But North Atlantic...

SAN FRANCISCO, July 25, 2011 /PRNewswire/ -- Sea World is responsible for the death of thousands of dolphins and whales, so states former Sea World biologist Dr. John Hall. That is the thread of the first comprehensive documentary film to explore the sordid history of the captive whale and dolphin display industry. A Fall From Freedom, an 82-minute film produced by San Francisco-based EarthViews Productions, includes interviews with scientists, marine mammal biologists, former trainers,...

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...

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...
