Opis:

Juvenile herring hunt for the very alert and evasive copepods in schools: The copepods can sense with their antennae the pressure-wave of the approaching herring and react with a fast escape jump. The length of the jump is quite consistent. The fish arrange in a grid of this characteristic jumplength. The copepods can dart about 80 times before they tire out. It takes 60 milliseconds to spread out the antennae again, and this timeslot is utilized by the herring to finally snap a copepod. A single juvenile herring would never be able to catch a large copepod ("Synchropredation" - results from in situ videos taken from the ATOLL laboratory).]]
