Fig. 3: Division of prey within sub-groups.

a, b 2018 data; c, d 2019 data. a, c For the scenario of four subgroups in 2018 and three subgroups in 2019 (due to very small group sizes in 2019 for the scenario of four subgroups), the relationship between the percentage of prey captured and the percentage of group members—sorted in descending order of their number of dash sequences—showing the unequal division of prey between group members. For the different subgroups— 2018: 1/4 (
), 2/4 (
) and 4/4 (
); 2019: 1/3 (
), 2/3 (
) and 3/3 (
), —approx. 70–80% of sardines are captured by less than 50% of the members. Group 3 is not shown in a, b – 2018 - because it only contained three members. Deviations from the diagonal dotted line show that the division of prey is unequal. b, d Within each of the subgroups, individuals with a higher number of dash sequences also had a higher total number of captures.
