    <p>Positive values represent increases at Tabuaeran. Percentage of surveys (B) in which nocturnal prey fish were sighted at Palmyra and Tabuaeran. Comparisons of the biomass of all large (≥10 kg) diurnal and cathemeral piscivorous predators (D) at both atolls. All values are mean, ±1 SE. Surveys marked with the same letters in each species grouping are not significantly different (after post-hoc correction).</p

    Examples of two species of nocturnal reef fish surveyed in this study: <i>Myripristis berndti</i> (A) and <i>Priacanthus hamrur</i> (B).

    <p>The large eye to body length ratios of these two species (<i>M. berndti</i>: 0.15; <i>P. hamrur</i>: 0.11) give evidence of their nocturnal lifestyle. Like many nocturnal fish, <i>M. berndti</i> and <i>P. hamrur</i> both dramatically increased in abundance at Tabuaeran where large daytime active predators were less abundant. Example diurnal fish <i>Chlorurus sordidus</i> (C) and <i>Epibulus insidiator</i> (D) exhibit the smaller eye to body length ratios (<i>C. sordidus</i>: 0.05; <i>E. insidiator</i>: 0.05) that are more characteristic of diurnal reef fish. These species were among the diurnal prey fish taxa whose abundance showed negative or weak responses to predator depletion.</p
