Relative velocity fluctuation (RLF), as function of body length (BL) in nauplii.

<p>RLF = (maximum velocity – minimum velocity)/average velocity). Regression lines are power laws fitted to the data. Blue circles, <i>T. longicornis</i>: Log(RLF) = −0.13Log(BL) +0.51 (r² = 0.06, p = 0.12, n = 63); red circles, <i>O. davisae</i>, Log(RLF) = −0.31Log(BL) +0.34 (r² = 0.10, p = 0.01, n = 82); green circles, <i>A. tonsa</i>, Log(RLF) = −0.71Log(BL) +0.34 (r² = 0.50, p<0.0001, n = 82); blue triangles, <i>T. longicornis</i> swimming (slope = −0.93, p = 0.49, n = 36).
