April 3 (UPI) -- Planktonic microbes are armed and dangerous. New analysis revealed the method used by plankton to fire projectiles at their prey and enemies.
"We think of plankton as the tiny alphabet soup of the ocean, floating around passively while larger organisms eat it," biologist Gregory Gavelis said in a news release. "But some planktonic microbes, like dinoflagellates, are predators and have developed incredible defensive and prey capture mechanisms."
