The fish at left stands out against the lighter waters above. At right the same fish—now with bioluminescent structures on its underside lit—blends in. Many deep sea creatures have evolved this...
Like other sea snakes , the turtle-headed sea snake ( Emydocephalus annulatus ) has fangs and venom. But its venom is weak so, instead of defending with a bite, the species tends to react to danger...
Starksia blennies, small coral reef fish with elongated bodies, have been well-studied for more than 100 years. But things are not always what they seem when it comes to fish. Using genetic analysis...
Nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that could provide the key to our understanding of one of the biggest threats to coral reef survival: Ocean Acidification...
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...
From parrotfish that cover themselves in a blanket of their own mucus to tiny pygmy sea horses, there are some bizarre sea creatures that live in coral reefs . In this slideshow you can explore some...
Researchers use Autonomous Reef Monitoring Structures (ARMS) like this one to study the diversity of coral reef organisms. They leave the structures underwater for about a year. Then they retrieve...
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...
Smithsonian zoologists inside the Curasub , a 5-person submersible. They're exploring the biodiversity of the deep reefs off Curaçao in the southern Caribbean. Read more and watch videos about the...
Flattened against a leaf, a tree frog blends right in with the mangroves. More about mangroves can be found in our Mangroves featured story.
As it clings to a red sea fan, a feather star ( Cenometra bella ) gently waves its slender arms—filtering bits of food from the water. Also known as sea lilies, feather stars are related to sea stars...
This male giant squid is on display in the Sant Ocean Hall at the Smithsonian’s National Museum of Natural History . It measures about 2.7 meters (9 feet) long and weighs a little more than 45.5...
Coral reefs are bustling cities of marine life, until rising ocean temperatures turn them into ghost towns. Can reefs spring back from devastating bleaching events? In this episode of the Podcast of...
The ocean is home to a phenomenal diversity of marine organisms. They have evolved to inhabit warm waters near the equator and the icy waters of the Earth’s poles. Marine life takes advantage of the...
Enric Sala has spent much of his career looking for the ocean's "time machines" -- areas rich in biodiversity and largely unaffected by humans. In this recorded webcast , Sala, a National Geographic...
Remotely located in the central Pacific Ocean, south of Hawaii, the Line Islands provide a remarkable research opportunity. The archipelago includes coral reefs reflecting the whole spectrum of...
Deep sea animals have to live in a very cold, dark, and high-pressure environment where they can't see a thing! To survive there, they've evolved some very strange adapations. Some make their own...
Squids, octopuses and cuttlefish, such as this Australian Giant Cuttlefish ( Sepia apama ), compose just one group of animals that call seagrass beds home. Clams and worms bury themselves in the mud...
