Table 1.
Prey categories used to calculate standardised diet compositions and trophic levels – compiled from Cortés [1] and Ebert & Bizzarro [2].
Table 2.
Average prey contributions in the standardised diets for the suborders Myliobatoidei and Torpedinoidei and taxonomic families based on species with samples greater than 20 stomachs.
Figure 1.
Prey category contributions to the standardised diets of each of the respective families and sub-families.
Box plot represents the median standardised diet percentage (central line) and 25th and 75th percentiles; bars represent 10th and 90th percentiles; closed circles 5th and 95th Percentiles.
