A marine scientist performs a genetic analysis on a sample of deep-sea coral to find out if it is a known species or one new to science. Find out how ocean scientists study deep-sea corals in our...
Branching corals, because of their more fragile structure, struggle to survive in acidified waters that surround the volcanic CO 2 seeps of Papua New Guinea. Read more about how reef scientist...
I still haven’t gotten beyond the ‘gee whiz’ factor of studying communities of animals in deep-sea coral habitats. Climbing over undersea mountains and along the steep cliffs of submarine canyons...
A fan-shaped colony of red coral ( Corallium sp.) on the Davidson Seamount provides a perch for three basket stars as they feed. See more pictures of coral in our Deep-sea Corals article.
Close to the volcanic CO 2 seeps, the vast diversity of corals that exists in less-acidic waters is replaced by a "monoculture" of boulder corals. These are less fragile and better suited to life in...
Scientists at the Smithsonian and partnering organizations have discovered a remarkably primitive eel in a fringing reef off the coast of the Republic of Palau . This fish exhibits many primitive...
A coral ( Montastraea faveolata ) has just spawned. Each of the hundreds of polyps living in the colony releases a small pink bundle of sperm and eggs. Read more about coral spawing and watch a...
