Have you ever seen a creature so unusual? This fish (22 cm long) is called a sea toad and studying them requires luck and the opportunity to descend into the deep waters where they live. Last week Dr...
This transparent cockatoo squid ( Leachia sp.), also known as a glass squid, lives in the depths of the ocean and has many adaptations to help it survive there. It retains ammonia solutions inside...
When a whale dies, the story has just begun. The massive carcass sinks to the seafloor, where it provides food for a deep sea ecosystem on the otherwise mostly barren seafloor. There are several...
Come along as scientist Dr. Brendan Roark narrates a submersible dive to collect and study deep-sea corals. Roark studies deep-sea corals to understand the history of the ocean and past ocean...
Methane gas, trapped deep within the Earth's crust, can slowly leak from cracks in the seafloor known as methane seeps. While we would never consider methane as food, in the deep sea where there is...
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...
Last week, Smithsonian research zoologists Dr. Jerry Harasewych and Dr. Martha Nizinski were in Curaçao looking for deep-sea marine gastropods and decapod crustaceans , respectively. I learned they...
Discovered in 2004 and named in 2009, this Gersemia juliepackardae coral has been spotted and collected at several seamounts in the northeast Pacific Ocean at depths of 500-2,000 m (1,640-6,562 ft)...
