Deep-spied Fish: Atlantic expeditions uncover secret sex life of deep-sea nomads 
US Source: Underwatertimes 2/21/2006

For centuries scientists have thought of deep-sea pelagic fish as nomadic wanderers, in part because information about them was so limited. However, new results from the ongoing Mid-Atlantic Ridge Ecosystems program (MAR-ECO), a Sloan Foundation-sponsored component of the Census of Marine Life, have revealed that these fishes may in fact be gathering at features such as ridges or seamounts to spawn. The research has important implications for how deep-sea ecosystems should be managed to prevent devastation by deep trawling activities. MAR-ECO research expeditions have also led to the discovery of as many as six fish species new to science and the collection of some unusually large deep-sea fish specimens.
 

"We're discovering all these patterns that we've never seen before," says Sutton, "and now we're working to figure out what they mean and how they got there. The Mid-Atlantic Ridge is proving to be an oasis in the desert , so to speak."

Pelagic fish are those species thought to spend the bulk of their time in open water, as opposed to staying near the seafloor. Classification has historically been determined based mainly on whether the fish are typically caught in open water trawl nets, or trawl gear that collects along the bottom. Deepwater pelagics include some of what most people would agree to be the most bizarre looking animals on the planet. Many, with their oversized fangs, aquatic scowls, and ingenious entrapment devices-- coupled with names such as "vampire fish from hell" and saber-toothed viper fish--are the stuff of pure nightmare save for their typically small sizes. Like the best nightmare sponsors, though, they remain mysterious.
