Nick Pyenson, the Smithsonian Institution’s curator of fossil marine mammals, compares the skeletons of ancient whales to the life-sized model of a North Atlantic right whale displayed at the National Museum of Natural History in Washington, DC. Whales have been evolving for more than 50 million years, and long before becoming ocean-dwelling giants, the earliest cetaceans walked on land.

An illustration of a harbor porpoise (middle) swimming with two other porpoises. Analyzing harbor porpoises’ echolocation clicks gave scientists a way to measure how closely they approach tidal power turbines. 

For Good or Ill, Porpoises Avoid Tidal Power Turbines

The finding is good news if it means the porpoises are staying safe, but it is bad if they are losing habitat in the process

Some chemical compounds used in sunscreens, such as oxybenzone and octinoxate, are facing scrutiny from legislators and environmental advocates. Scientists are looking to the ultraviolet light-blocking compounds produced by marine organisms as potential replacements.

Designing a More Environmentally Friendly Sunscreen

Scientists are sourcing new ultraviolet ray-blocking compounds from algae, seaweed, cyanobacteria and other marine creatures

Researchers have located a genetic mutation associated with smaller dogs.

Mutation That Gave Us Tiny Dogs Found in Ancient Wolves

The genetic factor that plays a large role in determining canine body size was around thousands of years prior to domestication

Seahorses build a strong pair bond—but if the couple is forcibly separated, they are more than willing to move on.

Very high resolution satellites give scientists a new way to find out when and where a large-bodied whale, such as a humpback or a sperm, is stranded

A tiger shark swims in the Bahamas. Over the past several decades, the predators ventured farther north in the northwestern Atlantic Ocean.

Some Tiger Sharks Are Migrating Farther North Due to Climate Change

The predator’s movements in the Atlantic Ocean could scramble ecosystems and endanger the sharks by sending them outside marine protected areas

Little is known about most magnapinnid, or bigfin squid, species. The individual pictured here was spotted by the NOAA ship Okeanos Explorer in the Gulf of Mexico. Recently, a magnapinnid was filmed in the Philippine Trench—the deepest ever sighting of a squid.
