zebra fish larvae (Matthew Henry)
Small fish, especially young ones, tend to swim quickly for an instant, stop and then zip away again. What accounts for such darting around? Briefly stopping may allow small fish to better feel the pull of predators, such as larger fish, that suck prey into their mouths. Researchers at the University of California at Irvine found that stationary zebra fish larvae in laboratory tanks are twice as likely as swimming ones to avoid piston-induced suction that mimics the water flow of a predator slurping up a meal.
