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

Sharks have young in three different ways. After internal fertilization, some species lay a thick egg case that encloses the shark embryo (seen in the photo here). Most species are ovoviviparous, which means that the shark hatches and develops within the female shark and is born live. A third way (viviparous) is similar to human development, where the young shark grows within the female and gets...Read more

These cancer cells have been treated with discodermolide, a chemical obtained from a sponge that grows on deep-sea coral reefs. It prevents the cells from dividing and spreading. Learn more about deep-sea corals in the multimedia feature " Coral Gardens of the Deep Sea " and about drugs from sea creatures in our conversation with Dr. Shirley Pomponi .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

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
