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

Climate and sea changes in the Southern Ocean create conditions that favor the growth of salps over krill , the latter of which are a vital food source for seals, whales, and penguins. Salps are filter-feeding tunicates that float through the water column, sometimes forming long salp chains, consuming phytoplankton and using jet propulsion to move. Read about their complex life history in “ The...Read more

Giant kelp ( Macrocystis pyrifera ) is large, brown algae that grows in dense forests along coasts around the world. Long stalks anchor each plant to the seafloor, and they grow meters high like giant trees towards the surface. Kelp forest ecosystems are home to a variety of animals, including seals, sea lions, whales, sea otters, gulls, terns, snowy egrets, great blue herons, cormorants, and...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
