Balmy temperatures can lead to conditions perfect for the spread of infectious diseases, Sanderson said. When sea ice melts too early in the season, seal pups must enter the water before they are ready to be weaned, leaving them weaker and more vulnerable to disease. Vanishing sea ice also means that seals and sea lions in cold regions will have less space to emerge from the water to rest, breed, or escape predators, forcing them to crowd more tightly together.
Wildlife around the world is exposed to plastic pollutants called endocrine-disrupting chemicals (EDCs). Not much is known about how these chemicals affect marine environments, though scientists have been studying them for years. According to The Guardian, killer whales, for instance,… Read More ›

“These are the second and third juvenile Humpbacks found dead on the Currituck Banks Peninsula in less than a week,” said the post. “Another was found on February 12 north of Oregon Inlet near Nags Head.”
“We believe the high count this year is partly explained by excellent viewing conditions, but it also appears to reflect increased food availability in the range center,” says Dr. Tim Tinker, a research ecologist who leads the USGS sea otter research program. “The boom in sea urchin abundance throughout northern and central California has provided a prey bonanza for sea otters, and that means more pups and juveniles are surviving to adulthood.”
Entanglements have surpassed ship strikes as a leading danger to right whales in recent years. Forty-four percent of diagnosed right whale deaths were due to ship strikes and 35 percent were due to entanglements from 1970 to 2009, the study said. From 2010 to 2015, 15 percent of diagnosed deaths were due to ship strikes and 85 percent were due to entanglements, it said.
“Historically, at this time of year, we would see nice little bunches (of orcas) swimming back and forth in front of the house,” said Ken, who lives on the west side of San Juan Island. But this year, the whales have broken up into small family groups and are traveling around in seemingly random patterns, presumably in search of whatever salmon they can find.
Each year around 650,000 whales, dolphins and other marine mammals are unintentionally caught and killed in fishing gear worldwide. Under the new rule, foreign fishermen must meet the same marine mammal protection standards applied to U.S. fishermen or their fish will be banned from the lucrative American seafood market.
A post-mortem of the creatures, found ashore near the town of Toenning in Schleswig-Holstein, Germany, showed their stomachs were full of plastic.
This plastic included a 13-metre-long (43-foot-long) fisherman’s net and a 70-centimetre (28-inch) piece of plastic from a car.
