Deep-sea fish adapt to some of the most extreme conditions on Earth. New research analyzing their evolution finds the same ...

Led by the Mariana Trench Environment and Ecology ... the researchers estimated when different fish lineages first ventured into the deep sea. Eels may have moved down some 100 million years ...

A new study analyzes the evolutionary history of 11 deep-sea species from environments stretching from the central Indian ...

Conducted under the Global Deep-Sea Trenches Exploration Program (Global TREnD), this study represents a comprehensive investigation of deep-sea fish adaptation, spanning genetic to ecological levels.

The researchers studied tissue from over 120 fish. They found that 50 to 60 percent of their diet came from ocean’s twilight ...
