Tiny aquatic organisms like plankton are considered passive drifters, moving at the mercy of ocean currents. But reporting in the Journal of Experimental Biology, scientists show some of these microorganisms don’t just drift—they surf. The researchers chose a zooplankton—the larvae of the common slipper shell snail. They placed 2000 of the larvae in a small tank equipped with eight water jets, which created different levels of turbulence similar to ocean currents. The scientists then added trace
