Semirostrum ceruttii
2014-03-14 11:30:12

Brett Smith for redOrbit.com - Your Universe Online Researchers from Yale University have announced the discovery of a new species of ancient porpoise with a massive underbite. According to a report published in the journal Current Biology, the newly discovered cetacean had a jaw that extended nearly 2.8 feet – a unique feature that was probably used to probe to seafloor for something to eat, the study team said. "The extinct porpoise is a bizarre new animal, with the mandible...

New Whale Fossil Species Sheds Light On Evolution Of Echolocation
2014-03-13 09:36:18

Lawrence LeBlond for redOrbit.com - Your Universe Online Echolocation is an important tool for several modern species, including bats and some birds. Previous research from New York Institute of Technology’s College of Osteopathic Medicine has found that this powerful navigational tool also existed in a 28-million-year-old relative of modern-day toothed whales, dolphins and porpoises. In new research, published in the journal Nature, Associate Professor Jonathan Geisler, of NYIT, and...

Fossils Reveal Eclectic Ancient Marine Mammals Of North Pacific
2014-02-06 08:47:30

redOrbit Staff & Wire Reports - Your Universe Online The pre-Ice Age marine mammals of the North Pacific were a diverse and fascinating lot, according to an analysis of hundreds of fossil bones and teeth excavated from the San Francisco Bay Area's Purisima Formation. Robert Boessenecker, a geology PhD student at New Zealand's University of Otago, put together a record of 21 marine mammal species that were fossilized 5 to 2.5 million years ago, including dwarf baleen whales, odd...

Genes Show How Whales Evolved For Oceans
2013-11-25 10:54:21

Brett Smith for redOrbit.com - Your Universe Online Approximately 54 million years ago, whales and other cetaceans diverged from land-dwelling mammals and gradually evolved to live a productive life at sea. A new study published in the journal Nature Genetics on Sunday revealed genetic evidence of how whales evolved the ability to dive deep into the ocean for long periods of time and how they developed a specialized feeding system that uses baleen instead of teeth. In the study, a...

High-Pitched Echolocation Helps Harbor Porpoises Avoid Killer Whales
2013-06-12 14:17:20

Lee Rannals for redOrbit.com — Your Universe Online Researchers from the University of Southern Denmark (SDU) have determined why harbour porpoises are doing so well in coastal and busy waters. The team wrote in the journal Frontiers in Physiology that these animals are able to thrive through the Northern Hemisphere due to their sophisticated echolocation abilities. Coastal waters like the ones harbor porpoises live in can be challenging for whales due to the risk of beaching and...

Whales are remarkably diverse, with 84 living species of dramatically different sizes and more than 400 other species that have gone extinct, including some that lived partly on land. Why are there so many whale species, with so much diversity in body size? To answer that, UCLA evolutionary biologists and a colleague used molecular and computational techniques to look back 35 million years, when the ancestor of all living whales appeared, to analyze the evolutionary tempo of modern whale...

When the ancestors of living cetaceans"”whales, dolphins and porpoises"”first dipped their toes into water, a series of evolutionary changes were sparked that ultimately nestled these swimming mammals into the larger hoofed animal group. But what happened first, a change from a plant-based diet to a carnivorous diet, or the loss of their ability to walk? A new paper published this week in PLoS One resolves this debate using a massive data set of the morphology, behavior, and...

Local officials of a Japanese coastal town said on Thursday they have gone ahead with their controversial dolphin hunt as animal-rights activists continue to protest them, AFP reported. Wakayama prefectural official Yasushi Shimamura said fishermen in Taiji caught about 100 bottlenose dolphins and 50 pilot whales on Wednesday, in their first catch since the fishery season started on September 1. An official at a local fishermen's cooperative said all whale meat will be sold for human...

A dead porpoise was found washed up on a Brixham beach on Thursday - the fourth found on Devon beaches this month. The animals have been found at Bigbury, Beesands, Scabbacombe and, most recently, St Mary's beach near Sharkham Point, Brixham. But rather than being taken for post-mortem analysis, the creatures had to be disposed of by local councils in landfill sites. This is due to a drop in funding for the National History Museum in London, which used to collect all animals washed up...
