A group of little-studied deep-sea-dwelling orcas sometimes rams prey and catapults sea lions, according to a report in PLOS ONE.Those observations by scientists from the University of British Columbia Institute for the Oceans and Fisheries (IOF) are notable because deep-water-grazing orcas may represent a new subcategory of killer whales, according to another study in Aquatic Mammals. Orca categories — called ecotypes — include residents, transients, and offshores. The “deep-water-transie ...read more

Rarely observed and shy by nature, it’s found in the temperate waters of the Southern Hemisphere.The pygmy has long been called a right whale because people thought that it looked like one, but many researchers have long disputed this notion because of a number of differences. For example, the pygmy right w ...read more

Learning chess was one of the experiences Vanderbilt chronicled in his book Beginners: The Joy and Transformative Power of Lifelong Learning (he also learned juggling, singing, and surfing) ...read more

The species, Dinocephalosaurus orientalis, swam the seas during the Triassic period, and the fossil itself dates back 240 million years. The fossil has fascinated — and baffled — scientists and the public alike. But previous fossil discoveries, as well a ...read more
