Figure 4 – Feeding efficiency vs concentration of sediment particles in the water. As higher concentrations of particles were added to the water, krill were less able to feel effectively (blue arrows). The yellow bars show an experiment conducted with small particles added to tanks; the purple bars show an experiment with large particles added. It required a much lower concentration of large particles (17 mg/L) to achieve the same effect that a higher concentration of small particles (100 mg/L) had on krill feeding efficiency (red circles). (Annotated version of Figure 3a and 3c in the paper.)
