Ryan Reisinger of the University of Pretoria in South Africa, one of the researchers who...

The Harderwijk Dolphin Center in the Netherlands announced that a porpoise dolphin has become only the second to give birth in captivity, but the birth has left the people questioning whether its a boy or girl. "Mum Amber and her baby, Kwin, are doing fine," the center said in a statement on Thursday. Another porpoise was born in captivity in Denmark in 2007. "As we don't know much about newborn porpoises, a team of Danish minders has come to help us," the statement said. Visitors are already...

Many of Washington State's sea otters are exposed to the same pathogens responsible for causing disease in marine mammal populations in other parts of the country, according to a study published by researchers from NOAA's Olympic Coast National Marine Sanctuary, the U.S. Fish and Wildlife Service and their partners. While the Washington sea otters do not appear to be suffering negative effects from the pathogens, they still face potential threats from infectious disease due to their...

Researchers report finding a stronghold for the Irrawaddy, one of the world's rarest freshwater dolphins, deep in the Bangladesh jungles. Scientists counted nearly 6,000 of the dolphins in the South Asian country's Sundarbans mangrove forest adjacent to the Bay of Bengal, the Wildlife Conservation Society said in a release. Before the find by the Wildlife Conservation Society there were only a few hundred of the Irrawaddy believed alive. This discovery gives us great hope that there is a...

Researchers say global warming is bringing food stocks closer to shore, causing the mass beaching of whales along Australia's coast, the AFP reported.Last week, nearly 90 long-finned pilot whales and bottlenose dolphins were beached along the Hamelin Bay on Australia's west coast in the last month.Experts say it took the total number of beached cetaceans in southern Australia beyond 500 in the past four months alone, including a single stranding of almost 200 on King Island.The...

A California wildlife photographer, out on Monterey Bay with a group of fellow professionals, was the only one to capture a sea otter holding a video camera. Enrique Aguirre told The Santa Cruz (Calif.) Sentinel he had the otter in his view finder before he noticed something strange. I was like, did I actually see an otter with a video camera or was I hallucinating?, he said. The otter was floating, holding the camera in its paws, the lens apparently aimed at the photographers on Capt. Yohn...

A U.S.-led study of the fossil of an extinct pregnant whale discovered in Pakistan suggests primitive whales gave birth on land. Researchers said the 47.5-million-year-old fossil reveals how primitive whales gave birth and provides new insights into how whales made the transition from land to sea. The researchers who made the discovery said they were at first perplexed by adult female and fetal bones found together. When we first saw the small teeth, we thought we were dealing with a small...

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...
