A specimen from the Smithsonian’s squid collection and videos of a mystery squid helped scientists identify a new family of deep sea squid—the Magnapinnidae, known as the bigfin squids. More about...
Sharks come in all sizes. The largest is the whale shark , which has been known to get as large as 18 meters (60 feet). The smallest fits in your hand. And the great white shark is somewhere in the...
Copepods are aquatic crustaceans found in every marine habitat, from surface waters to the deep sea. With over 13,000 described species, they are among the most abundant of all multicellular animals...
The ocean is not as natural as it once was. Where there used to be large predators that we took for sea monsters, now there are tiny fish and jellyfish. But there are a few untouched places left in...
How many animals swim in the sea? It's not easy to count them all. To get a feel for the ocean's diversity, scientists, such as those involved in the Census of Marine Life , sail out on research...
About the IBRC The Indonesian Biodiversity Research Center (IBRC) was founded in June 2010 by a group of seven international research institutions to promote biodiversity stewardship in Indonesia...
Smithsonian researchers collected a cave basslet ( Liopropoma mowbrayi ) from the deep reefs of Curaçao , in the southern Caribbean. They used a state-of-the-art submersible to obtain the specimen...
It may be the last place you’d expect to find corals—up to 6,000 m (20,000 ft) below the ocean’s surface, where the water is icy cold and the light dim or absent. Yet believe it or not, lush coral...
When we think "Africa," we think of the "Big Five"—lions, elephants, leopards, buffalo and rhinos—that crisscross the African Savannah. Few would imagine that there could be more natural beauty on...

Nudibranchs (often casually called sea slugs) are soft-bodied, marine snails that have lost all trace of an external shell. The name “nudibranch” translates from the Latin as “naked gills.”...
Today’s discoveries about our planet’s biological diversity build upon the research of previous generations of scientists. The Biodiversity Heritage Library (BHL) is a digital library committed to...
Sea squirts, or ascidians, are a diverse class of marine invertebrates representing about 2,300 species. As adults they are sessile animals (attached to the bottom) that feed by filtering food from...
