In 2012, the long-elusive giant squid was finally filmed live in its natural habitat. The squid was found by placing glowing lures outside of a submersible to mimic jellyfish, which typically...
This radio device is used to track North Atlantic right whales. Suction cups hold the device to a whale's back, where it records data such as depth, water, temperature, and underwater sounds. These...
Searching for useful chemicals, marine scientists grow bacteria associated with deep-sea coral on nutrient agar to identify the bacteria and test their metabolic and biochemical capabilities. Some...
Smithsonian researchers are using this five-person submersible to study the biodiversity of the deep reefs of Curaçao in the southern Caribbean. Read about their adventures in the Summer in a Sub...

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...
The Hawaii Undersea Research Laboratory’s Pisces V submersible is lowered for a dive to study deep-sea corals. Learn more about research into deep-sea corals in the multimedia feature " Coral Gardens...
Great White Sharks are stealthy hunters and the secret is in their skin. Shark skin is covered by tiny flat V-shaped scales, called dermal denticles, that are more like teeth than fish scales. These...
