Mean of standardised percent prey weight within each fish weight (g) group, for the prey types together contributing at least 90% of the SIMPER within group similarity for one or more groups. SIMPER percentage contribution to within group similarity:
3–10%;
10–30%;
>30%; no superscript, not identified by SIMPER as characteristic for that group; n, sample size.
