There is a huge amount of plastic trash floating in the ocean, which endangers wildlife that eats or gets tangled in it. Reducing the amount of plastic trash in the ocean doesn't seem that hard; people just need to use less plastic, such as packaging, drinking straws and plastic bags. But it can be very hard to break people's habits. In 2002, Ireland made a simple change: they started charging a...Read more

Sponges are animals that eat tiny food particles as they pump water through their bodies. They are very common on Caribbean coral reefs, and come in all shapes, sizes and colors. There is great variability in their size: some sponges are very small (just a few centimeters) while others are very big, like the giant barrel sponge, which can be six feet wide. Even sponges of the same species can...Read more

Polarized sunglasses have become the norm for humans when they want to filter out the strong glare from the sunlight bouncing off of water in a horizontal direction. But how do animals do that live in the water full time see over the glare? Over time some animals, including fish, crabs and shrimp, have evolved built-in polarized vision . In addition to helping them see underwater, mantis shrimp...Read more

See more beautiful ocean photos in our slideshow of winners from the 2010 Nature's Best Ocean Views photo contest. These Adélie penguins live in Antarctica and rely on tiny crustaceans, called krill, as their main...Read more

Fish swim around the wreck of the HMT Bedfordshire , an Arctic fishing trawler that was converted into an anti-submarine warship during World War II. Originally part of Great Britain's Royal Navy, it was sent to assist the United States Navy in 1941. In Spring 1942, the HMT Bedfordshire was hit by a torpedo sent from a U-boat and sunk off the coast of North Carolina, killing all 37 crewmembers...Read more

One of the smallest shearwaters in the Atlantic, Audubon's Shearwater ( Puffinus lherminieri ) is about the size of an American Robin. They breed on small islands in the Carribbean, and commonly forage around the floating Sargassum endemic to the North Atlantic. Audubon's shearwaters prefer warm, tropical waters, so do not migrate long distances like other shearwaters; however, they are...Read more

Follow a journey with satellite tags placed on bull sharks and tarpon. Both of these large predatory fish are found in coastal in-shore ecosystems and the two species have similar diets. If given the opportunity, bull sharks will catch and consume tarpon. However, it remains unknown if tarpon adjust their movements to avoid being killed by the sharks. Using the information gained by the satellite...Read more

When most people think of catfish, they think of a freshwater fish. But the striped eel catfish ( Plotosus lineatus ) is found in marine systems including coral reefs, estuaries, tide pools and other coastal areas of the Indo-Western Pacific. The juveniles of the fish school in groups of up to 100, while the adults tend to stick to themselves or in smaller groups. Watch out for their spines: they...Read more

Watch as a team of wave chasers heads to Somoa where they search for an undersea river five kilometers beneath the ocean's surface. There they measured skyscraper-sized internal gravity waves, which break and produce strong turbulence underwater. Understanding these deep waves and flows is critical to understanding more about the Earth's climate and can help to improve climate models. The team is...Read more
