LONDON (Reuters) - Sleep-deprived mothers of newborn babiesshould spare a thought for bottlenose dolphins and killerwhales. A study has shown the young of those two species do notsleep at all during the first month of life. They are active 24hours a day -- and their mothers have learned to cope. "Somehow these seafaring mammals have found a way to copewith sleep deprivation, facilitating rather than hindering acrucial phase of development for their offspring," Dr JeromeSiegel, a...

If you thought the sleep-deprived months with your newborn were tough, pity the poor mother dolphin or killer whale. Reporting in the June 30 edition of the peer-reviewed journal Nature, UCLA/Veterans Affairs neuroscientists report a developmental pattern in bottlenose dolphins and killer whales that is unique from other mammals, with calves of both species active 24 hours a day during their first month. The mother also has minimal sleep during this period, but unlike all other mammals always...

LONDON (Reuters) -- Sleep-deprived mothers of newborn babies should spare a thought for bottlenose dolphins and killer whales. A study has shown the young of those two species do not sleep at all during the first month of life. They are active 24 hours a day -- and their mothers have learned to cope. "Somehow these seafaring mammals have found a way to cope with sleep deprivation, facilitating rather than hindering a crucial phase of development for their offspring," Dr Jerome Siegel, a...

LONDON (AP) -- A British university on Tuesday announced plans for what it called the largest international survey of whales, dolphins and porpoises on the European Atlantic continental shelf. Seven ships and three aircraft will be used in the survey by the Sea Mammal Research Unit at the University of St. Andrews in Scotland. They will conduct an intensive survey of the European Atlantic continental shelf to map the distribution and estimate the abundance of cetaceans. The survey,...

BUSSELTON, Australia -- Hundreds of volunteers worked throughout the day to free about 70 whales who stranded themselves on a beach near this Western Australian town. One of the false killer whales died in the beaching but the massive public turnout managed to save the others, local wildlife officials said. The state's Department of Conservation and Land Management (CALM) said a pod of more than 60 whales beached themselves near Busselton, 230 kilometres (143 miles) south of Perth, at about...

HONOLULU -- A bill passed by the U.S. House last week would provide $2.2 million to the University of Hawaii to research the effects of sound on whales and dolphins. Environmentalists have argued that the technology such as sonar could harm sea life which use sound waves to communicate. Paul Nachtigall, director of the Marine Mammal Research Program at Hawaii Institute of Marine Biology, said there is a big concern about the hearing of animals in the ocean, particularly loud sounds placed...

SOUTHAMPTON, N.Y. (AP) -- It takes a strong stomach and a keen understanding of whale anatomy to do Julika Wocial's job - and you've got to wield a mean flensing knife. A recent pleasant spring morning finds Wocial perched atop a decomposing whale carcass 60 feet long, hacking away at the deceased beast's flesh with a gruesome instrument that looks like a surgeon's scalpel blown up to the size of a kitchen broom. She pauses to brush away an errant strand of hair, then reaches into her...

MYSTIC, Conn. (AP) -- After bringing in a parade of males and watching for years as nature never took its course, scientists at Mystic Aquarium have performed what is believed to be the first artificial insemination of a beluga whale. Aquarium scientists, with help from their peers at Sea World, artificially inseminated Kela, a 24-year-old beluga, on Thursday morning. After giving the whale hormones to induce the release of an egg into the reproductive tract, workers used a crane to lift...

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...

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...

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,...
