Scientists thought fish saved energy by swimming in flat diamond shapes, but study shows they actually prefer swimming in 3D ...

For 50 years, scientists believed that schools of fish would save the most energy by swimming in flat diamond formations.

A new study suggests fish may swim together in turbulent water to conserve energy. Animals. Researchers have a new idea about why fish swim in schools. August 5, 2024 4:37 AM ET.
