Packs of hunting dogs, troops of baboons, herds of antelope: when people observe social animals, they are often struck by how intelligent they seem, and recent studies suggest that sociality has played a key role in the evolution of larger brain size among several orders of mammals. But new research from two evolutionary biologists, John Finarelli of the University of Michigan and John Flynn of the American Museum of Natural History, calls this hypothesis into question"”at least for the...

Researchers have confirmed the first ever sighting of a white southern elephant seal on a sub-Antarctic beach, BBC News reported. Unusual colors are more common in eared seals such as sea lions and fur seals, but such a thing is rare for true seals, a group that includes elephant seals. The journal Polar Biology published details of the seal, which has creamy white fur but normal brown eyes and nose. Ryan Reisinger of the University of Pretoria in South Africa, one of the researchers who...

Scientists from Canada and the U.S. have discovered the skeleton of a previously unknown web-footed carnivore in Canada's Arctic. The researchers said their discovery sheds light on how seals developed from land-based mammals. The primitive animal, known as Puijila darwini, measured around 43 inches from nose to tail, and had a body similar to that of an otter, but a skull akin to a seal. New research suggests Puijila is a "missing link" in the evolution of the group that today includes...

How do the many carnivorous animals of the Americas avoid competing for the same lunch, or becoming each other's meal? A possible answer comes from a new study by a pair of researchers at the University of California, Davis. Their large-scale analysis shows that it's not just chance that's at play, but avoidance strategies themselves that have been a driving force in the evolution of many carnivores, influencing such factors as whether species are active daytime or nighttime, whether they...

Hunted to near extinction, sea otters are making a steady comeback along the Pacific coast. Their reintroduction, however, is expected to reduce the numbers of several key species of commercially valuable shellfish dramatically, such as sea urchins and geoducks. Despite of this potential conflict, Kai Chan, an NSERC-funded researcher at the University of British Columbia, believes there is a way to ensure Canadian First Nations fishers can benefit from the otters' presence. "Efforts to...

HONOLULU -- Young female Hawaiian monk seals will be raised in captivity as part of a plan unveiled Wednesday to save their diminishing population from extinction. The recovery plan will nab about 50 malnourished young seals each year, put them in protective custody to help them survive their early years, and then release them back into the ocean to start new families. Scientists estimate there are only about 1,200 Hawaiian monk seals left, and their population has been shrinking by 4 percent...

The best oceanographers in the world never studied at a university. Yet they know how to navigate expertly along oceanic fronts, the invisible boundaries between waters of different temperatures and densities. These ocean experts can find rich fishing in places and at depths that others would assume are barren. They regularly visit the most interesting and dynamic parts of the sea. Sea lions, seals, sharks, tuna and other top ocean predators share some of their experiences with human...

Philadelphia, PA -- Otters cavorting in the water is a scene with which we're all familiar. Yet, unlike many other mammals that spend a considerable amount of time in the water"“polar bears, seals, dolphins, and whales"“river otters do not have a thick layer of body fat to keep warm. They rely, instead, on a few unique adaptations; namely, their fur and the densely packed layer of specially adapted underhairs. Using scanning electron microscopy and polarizing light...

The African Striped Weasel (Poecilogale albinucha), is the only member in the genus Poecilogale. It is a small black and white weasel native to sub-Saharan Africa. The African striped weasel lives in forests, wetlands, and grasslands. It is a nocturnal hunter of small mammals, birds, and reptiles. The weasel kills its prey by whipping its own body and kicking, making use of its thin, lithe, muscular body to stun and tear the prey item. It sometimes stores its prey in its burrow instead of...

The Siberian Mountain Weasel (Mustela sibirica), is also known as the Siberian Weasel, Kolinsky or Himalayan Weasel. It is a rust colored relative of the weasel family. Siberian weasel fur makes the finest water color or oil paint brushes and is especially sought after by artists. The so-called kolinsky sable-hair brush is produced using the winter fur of the male Siberian weasel, not sable.

Leopard Seals are the second largest species of seal in the Antarctic (after Southern Elephant Seals), and are near the top of the Antarctic food chain. Orcas are the only natural predators of Leopard Seals. They can live twenty-six years, possibly more. Leopard seals are large and muscular, with dark grey backs and light grey stomachs. Their throats are whitish with the black...

The sea otter (Enhydra lutris) is a large otter native to the North Pacific, from northern Japan and Kamchatka east across the Aleutian Islands south to California. The heaviest of the otters, sea otters are the only species within the genus Enhydra. They were hunted extensively for their luxurious fur. Its estimated that a half million to a million otters were killed over time. The population is thought to have been 150,000 to 300,000 historically before the years of the great hunt....
