Studies are classified as either field surveys or studies measuring predator gape (i.e., gape-limit). The estimate is classified as a continuous maximum model (max. model), a single maximum value (i.e, 100th percentile; max. value), or a 90th percentile value (90th %-tile).
a—d correspond to literature derived estimates shown in Fig 2.
