Researchers reported on Monday, that older mothers may do a better job raising their children than younger, less-experienced moms, amongst killer whales.The researchers looked over 30 years of data to find that calves born to the oldest killer whales were 10 percent more likely to survive the critical first year of life than calves born to younger mothers."Older mothers appear to be better mothers, producing calves with higher survival rates," Eric Ward of the Northwest Fisheries Science...

Dolphins are the foodies of the ocean, deemed so because of their specific and complicated measures to purge cuttlefish of ink and bone, Australian scientists announced on Friday. A female Indo-Pacific bottlenose dolphin was seen prepping her cuttlefish for consumption in the Spencer Gulf, located in Australia. "It's a sign of how well their brains are developed. It's a pretty clever way to get pure calamari without all the horrible bits," Mark Norman, the curator of mollusks at Museum...

The U.S. Geological Survey says central California sea otters risk higher exposure to disease-causing parasites due to the food they eat and where they feed. Researchers said sea otters that eat small marine snails are at a higher risk of exposure to Toxoplasma gondii, a potentially deadly protozoal pathogen, than animals that feed exclusively on other prey. Sea otters living along the coast near San Simeon and Cambria are more at risk than sea otters outside that area. Recovery of the sea...

Sea otters living along the central California coast risk higher exposure to disease-causing parasites as a consequence of the food they eat and where they feed. Sea otters that eat small marine snails are at a higher risk of exposure to Toxoplasma gondii, a potentially deadly protozoal pathogen, than animals that feed exclusively on other prey, while sea otters living along the coast near San Simeon and Cambria are more at risk than sea otters that live outside this area. Similarly, sea...

A new study of pygmy killer whales shows that those living off Hawaii tend to stay close to the islands and don't swim out to the open ocean, researchers said. One of the least understood marine mammal species, there are very few of the whales (probably less than 200 individuals) in this distinct pygmy killer whale population off the islands. The research published Tuesday in the journal Marine Mammal Science suggests the population's limited number makes it more vulnerable than other whale...

CUMBRIA, England and FORT LAUDERDALE, Florida, December 30 /PRNewswire/ -- - Key Words: Dolphin, Cetacean, Acoustics, Holography, Language, CymaScope In an important breakthrough in deciphering dolphin language, researchers in Great Britain and the United States have imaged the first high definition imprints that dolphin sounds make in water. The key to this technique is the CymaScope, a new instrument that reveals detailed structures within sounds, allowing their...

Research suggests that the bizarre teeth of male beaked whales have evolved to help females choose their mates. Apparently, the males use the two teeth on the outside of their jaws not for eating, but for scratching each other. DNA analysis shows the teeth probably evolved as secondary sexual traits to help females select males of the right species, scientists said. Beaked whales make up the least known group of whales or dolphins. They spend most of their time deep in the ocean foraging for...

Scientists say harbor seals (common seals) are vanishing along coastlines across the northern hemisphere at an alarming rate. Researchers from St Andrews University say numbers have halved in the hardest hit area, the Orkney Islands, since 2001 - falling almost 10% each year. Professor Ian Boyd of the Sea Mammal Research Unit said there would soon be no harbor seals left in some areas if the mysterious decline continues. Marine biologists currently have no explanation for the disappearances...

Eagles shift their diet from aquatic marine animals to birds Sea otters are known as a keystone species, filling such an important niche in ocean communities that without them, entire ecosystems can collapse. Scientists are finding, however, that sea otters can have even farther-reaching effects that extend to terrestrial communities and alter the behavior of another top predator: the bald eagle. In nearshore marine communities, towering kelp can reach heights of 250 feet and function much...

World in brief TOKYO Dolphins at a marine park in Japan are on a low-fat diet after developing pot bellies and failing tasks in their aquatic performances. All 19 dolphins at Kinosaki Marine World are on a weight loss and exercise programme. (c) 2008 Independent, The; London (UK). Provided by ProQuest LLC. All rights Reserved.

Marine Otter, Lontra feline
2012-12-28 15:09:41

The marine otter (Lontra feline) is a member of the weasel family, and can be found in South America. It prefers a habitat in rocky coastal areas, with a range that includes the entire coastline of Chile and extends to southern Peru and Argentina. It has been found on the Falkland Islands, but individuals here do not represent a constant population. Unlike other species of otter, the marine otter chooses to live near waters with high winds and swells. It may use caves and crevices as dens,...

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...

Mediterranean Monk Seal, Monachus monachus
2012-06-23 10:50:34

The Mediterranean monk seal (Monachus monachus) is a rare pinniped, or “fin-footed mammal” that can be found in areas of the Mediterranean Sea, as well as in the Atlantic waters of the Tropic of Cancer. Not much is known about the chosen land habitats of this seal, but until the 20th century, it could be seen relaxing or pup rearing on open beaches. It now dwells in underwater caves and caverns in order to escape human actions including tourism and expansion. The Mediterranean monk...

Profilicollis
2014-01-05 00:00:00

Profilicollis is a genus of acanthocephalan parasites that are found in crustaceans and shorebirds. Profilicollis parasites use decapod crustaceans as intermediate hosts and species of shorebirds as definitive hosts. The parasite first develops in mole crabs of North and South America. After it infects a mole crab, it becomes dormant until the crab is eaten by a suitable bird, such as a Surf scoter or Herring Gull. Once the parasite has passed through the stomach of the bird, it develops...

Chinese White Dolphin, Sousa chinensis chinensis (known as rare pink dolphins)
2012-05-25 11:45:30

The Chinese white dolphin, otherwise known as the Indo-Pacific humpback dolphin, is a species of humpback dolphin that can be found in the waters of Southeast Asia. When breeding, they will travel to the waters around South Africa to Australia.  There are currently two recognized subspecies of the Chinese white dolphin. The coloring of the Chinese white dolphin can vary due to age and location. When born, calves are actually black, but will change to grey, then pink with white spotting,...
