Fig. 5. Mean (± s.e.m.) pectoral (A) and anal (B) fin angles in 20 ms bins from 100 ms prior to maximum gape to 60 ms after maximum gape for bluegill sunfish (red circles) and largemouth bass (blue squares). Shaded areas indicate the time prior to maximum gape and unshaded areas indicate the time following maximum gape. Note that largemouth bass protract their pectoral fins more than bluegill during braking. Both species abduct their anal fins greatly after prey capture.
