Fig. 3. The distribution of amplitude, H, and span, B, along the length of swimming cod (N=9) and plaice (N=10). (A) Specific amplitudes of cod at all values of h, (B) specific amplitudes of plaice, (C) specific spans of cod and (D) specific spans of plaice. Amplitudes, and the span of the body and fins, are normalized to total body length (L). Locations along the body length are normalized to total length as relative position along the body. Data in B are shown only for plaice swimming at the bottom and at a height of 50 mm for clarity. Values are means ± 2 S.E.M.
