Fig. 10. (A) Escape response of Clyde herring larva (Clupea harengus) 18 mm total length, filmed at 200 frames s^-1. (B) Maximum velocity attained during escape responses in Clyde herring larvae reared at 5 °C (open circles, dashed line) and 12 °C (filled circles, solid line) until first feeding, when they were transferred to ambient seawater temperatures. Each point represents an escape response from one larva. First-order linear regressions were fitted to the data. 5 °C, U_max=-3.12TL^1.92, r²=0.42, P=0.002; 12 °C, U_max=2.20TL^1.21, r²=0.48, P=0.001), where U_max is maximum swimming velocity (m s^-1) and TL is total length (mm).
