Swimming in schools has massive energy-saving benefits for fish. A study in “water tunnels” has found that fish use half as much energy swimming at high speeds if they are in a school rather than ...

Just as you might look down at the sidewalk as you walk, fish look downward when they swim, a new study by a Northwestern University-led international collaboration has confirmed. The study is the ...

A new study of giant danios (not pictured) suggests schools of fish save 79 percent more energy in turbulent conditions than fish swimming individually. Gordon Firestein via Wikimedia Commons under CC ...

Swimming through turbulent water is easier for schooling fish compared to solitary swimmers, according to a study published June 6 th in the open-access journal PLOS Biology by Yangfan Zhang of ...

Sometimes less is more. Researchers accurately modeled dynamic fish schooling by incorporating the tendency of fish to focus on a single visual target instead of the whole school, as well as other ...

A species of anglerfish spends their whole lives swimming upside down, scientists have found. An international team of researchers published these findings in a new study in the Journal of Fish ...

A northern pike is seen swimming in this undated photo. Northern pike are native to much of Alaska, but not to the Southcentral region south of the Alaska Range. Illegal introductions that started in ...

New simulations show that fish look downward when they swim because the stable riverbed below them provides more reliable information about their swimming direction and speed. Just as you might look ...
