Figure 2. Image from the ecoSCOPE showing a school of juvenile
herring Clupea harengus feeding in a micropatch of copepods.
Herring A and B in typical s-shape shortly before attacking a copepod
upwards. Herring C shortly after an attack during a u-turn. In this
position the silvery sides produce an intense light-flash. Herring D
shortly later on his downward return to his old school position.
Herring E starting a new attack upwards. Due to the deflection of light
by phytoplankton and microparticles the copepods are not visible from
the distance of the optics.
