Mesopelagic fish, long overlooked in ocean chemistry, are now proven to excrete carbonate minerals much like their shallow-water counterparts—despite living in dark, high-pressure depths. Using the ...

The backward-swimming deep-sea fish typically measured between 1 and 2 feet in length and were seen at depths of roughly 2.8 miles to 4 miles down, the study said.

They tend to stick together, and they like to swim against the current. MARTÍNEZ: By studying these fish in a lab, the researchers could compare solo swimmers to those in groups.

Swimming in schools makes fish surprisingly stealthy underwater, with a group able to sound like a single fish. The new findings by Johns Hopkins University engineers working with a high-tech ...

Like Olympic cyclists, fish expend less effort when swimming in tight groups than when alone. The finding could explain why some species evolved to move in schools. By Katrina Miller You’ll ...
