Repeated exposure decreases fragmentation. Notably, not all ingested beads were fragmented in the current study. To further explore this observation we compared the proportion of frag- ments to whole beads isolated from whole krill homogenates and faecal pellets exposed to the high and low treatments. The pro- portion of fragmented beads egested by the krill on days 1 and 4 were compared to assess the effect of repeated exposure. An extra sample point was added on day 4 to assess fine scale temporal variation within a daily cycle after repeated exposure.
