"Macro shot of a whip coral goby, taken in Fiji during a trip to the Somosomo Strait," wrote Erwin Poliakoff of his image , a winning selection in the Portraits of Planet Ocean Flickr contest . Whip coral gobies ( Bryaninops yongei ) live on coral reefs throughout the Indo-Pacific, where they are found on a single species of coral: black wire coral ( Cirrhipathes anguina ). The tiny fish find...Read more

Plastic does not biodegrade; it photodegrades, which means that sunlight breaks it down into smaller and smaller pieces. These bits of plastic and plankton were collected during a 3:00 am manta net tow, and are just a sample of the plankton-like plastic pieces collected on every trawl in the gyre. If you were a fish, you could not tell the difference between plankton (your natural food source)...Read more

A close up view of Phoenix and the rough patches of skin known as callosities that are found on all North Atlantic right whales . These callosities are inhabited by small amphipods called whale lice and they can be used to identify an individual right whale much like fingerprints. More about the right whale can be found in our Tale of a Whale featured story .Read more

Giant clams are one of the many wonders of coral reefs. They can grow up to five feet wide, weigh over 400 pounds, and live for 100 years! They power all that bulk by filter feeding microbes and particles from the water, siphoning hundreds of gallons of water per day. Like corals, they also have a symbiotic relationship with photosynthetic algae called zooxanthellae that live in the fleshy part...Read more

Standing at twice the height of the Adélie penguins, emperor penguins are the largest of the penguin species and can grow to be 100 pounds. This species breeds directly on the ice: a female lays her one egg and then passes it to the male to protect while she returns to the cold water to forage for food. See more photos from Antarctica's Ross Sea in our slideshow .Read more

Munch, munch. The queen parrotfish ( Scarus vetula ) scrapes algae from Caribbean coral reefs with its parrot-like beak. While feeding, hard stone and coral inevitably get mixed into its lunch, which in turn gets ground up by the fish and deposited back into the ecosystem as sand. This fish is an adult male. But when young, parrotfish have the ability to change sex, depending on the population’s...Read more

Riftia tubeworm ( Riftia pachyptila ) colonies grow where hot, mineral-laden water flows out of the seafloor in undersea hot springs—such as the Guymas Basin of the Gulf of California at 2,000 meters (6562 feet), where MBARI took this photo. As volcanic activity deep below the seafloor changes, sometimes these hot springs stop flowing. In this case, the entire worm colony may die off. But new hot...Read more

The shortfin mako shark ( Isurus oxyrinchus) is found offshore in tropical and warm temperate waters of all oceans, but has been known to travel to cooler waters at times. It is very strong and the fastest known species of shark, reaching moving speeds of 31 mph (50 kph) with bursts up to 46 mph! These qualities make the shortfin mako a prized catch among recreational fisherman. The mako is also...Read more

This photo of a freshly cut dorsal fin from a scalloped hammerhead shark ( Sphyrna lewini ) , was taken in 2006 on a long-lined fishing boat in Cocos Island, 300 miles off the Pacific coast of Costa Rica. Cocos was declared a UNESCO World Heritage site and is the home to one of the world's richest shark populations. It has also become a major target for long-lined shark fishing. Every year,...Read more
