Ships moving through a busy channel off Washington state's San Juan Island are slowing down this summer as part of a study to determine whether that can reduce noise and benefit a small, endangered population of killer whales.
A young beluga whale looks down as it is winched in a net onto the deck of a rusty Russian ship moored at a far-eastern port.
Endangered killer whales that frequent the inland waters of Washington state are having pregnancy problems because they cannot find enough fish to eat, according to a new study.
The great white shark is one of the ocean's most powerful predators, yet it is sometimes prey for orcas that killed several of the formidable creatures off South Africa's coast this month.
Killer whales are on an unprecedented killing spree in California's Monterey Bay, attacking and feeding on gray whale calves, a marine biologist said.
The last orca has been born in captivity at a SeaWorld park in San Antonio just over a year after the theme park decided to stop breeding orcas following animal rights protests and declining ticket sales.
When the mighty orca breaks to the surface and exhales, the whale sprays an array of bacteria and fungi in its his breath, scientists said, some good, and some bad such as salmonella.
The federal government is considering whether it should set up an area off Washington's San Juan Island where endangered killer whales would be protected from motorboats and other disturbances.
The jury is still out as to why hundreds of killer whales (orcas) flock to a location above the continental shelf near Bremer Bay on WA's south coast.
