HONOLULU -- Rain falling on the surface of the ocean can be heard more than a mile deep, and at some frequencies it's louder than passing ships, according to oceanographer Jeff Nystuen. Nystuen, of the Applied Physics Laboratory at the University of Washington, is one among scientists studying how sound travels through the ocean, to better understand how loud, man-made noises might affect marine creatures. "We don't really know what is too loud underwater, and we need to know what the...

ANCHORAGE, Alaska -- Sperm whales in the Gulf of Alaska are likely using the sounds of fishing boat engines as underwater dinner bells to hone in on longlines hung with valuable sablefish, scientists said. The engines make loud, erratic bubbling noises as fishermen maneuver their boats while winching up hundreds of bottom-dwelling sablefish. "That's the whales' cue," said Jan Straley, an assistant professor at the University of Alaska Southeast who since 2002 has helped lead an ongoing...

JOHANNESBURG -- Ten dead Irrawaddy dolphins have been found in Cambodia's Mekong river, eight of them calves, pushing one of the rarest cetaceans nearer extinction, the environmental group WWF International said on Friday. The deaths mean a 10 percent drop in the number of Irrawaddy dolphins living in the Mekong, previously thought to be between 80 and 100. They are restricted to a 190km (115 mile) stretch of the river in the Cambodia/Laos border area. There are believed to be about 1,000 of...

By Jeremy Lovell LONDON (Reuters) The northern bottle-nosed whale that made world headlines when it strayed into the River Thames in central London two days ago has died as rescuers were trying to rush it to safety aboard a barge. The news follows a sharp decline in the health of the adolescent 18-foot whale after initial optimism that it could be returned to freedom. "I am afraid it had a convulsion and died at 1900 hours," Tony Woodley of British Divers Marine Life Rescue told...

LONDON -- A marine mammal expert conducted a necropsy Sunday on the whale that wandered into the River Thames, hoping to determine what caused the 20-foot-long animal to veer off course and splash through central London before dying during Saturday's rescue attempt. The Zoological Society of London said it hoped preliminary results on what killed the Northern bottlenose whale would be available Wednesday. Paul Jepson, who has conducted government-funded research into why dolphins and...

By Jeremy Lovell LONDON -- A small whale swam up the River Thames to central London on Friday, a rare event which drew large crowds of sightseers and brought traffic to a standstill. But as the whale twice tried to ground itself in the shallow waters, concerns grew that it might not survive. As the Northern Bottle-nosed Whale beached in front of London's landmark Battersea Power Station, three men waded into the river hitting the water and then punching the air in celebration as it swam off....

OSLO, Norway -- Killer whales have the highest concentration of man-made toxins of all Arctic mammals tested in Europe because of the oceangoing predators' taste for fatty fish, according to a study released Monday. Man-made toxins, such as PCBs, build up in animal fat and become more concentrated in moving up the food chain. Most toxins, often from household products, are carried to Arctic waters by ocean currents, winds, or in migratory fish and animals. "Killer whales can be regarded as...

BOSTON -- Animal protection workers were investigating on Monday the mass stranding and death of 24 pilot whales and 15 dolphins during a winter storm on Cape Cod in Massachusetts. Strong winds and tidal surges during a powerful storm on Friday likely trapped the mammals, leading to the biggest mass stranding of whales on Cape Cod in three years, said Kristen Patchett of the Cape Cod Stranding Network. Most of the dolphins and whales died Saturday. Animal welfare workers euthanized seven of...

By Nita Bhalla NAIROBI (Reuters) - Naval maneuvers and submarine sonars in oceans are a new factor among many threatening dolphins, whales and porpoises that depend on sound to survive, the United Nations and marine experts said on Wednesday. A U.N. Environment Program (UNEP) report included underwater sonar and military maneuvers as the smallest factor on a list of major threats to some 71 types of small marine mammals, known as cetaceans, at risk. "While we know about other threats such as...

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

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,...
