closePublisher's Note: Errors in author contributions, supporting information Video S1 legend, and Figure 4 legend.

In the Author Contributions section, Robert H. Waldrop (RW) should be listed as one of the persons who conceived and designed the experiments.
The correct legend for supporting information file Video S1, "Chronology of sleep-like behavior in representative cuttlefish ‘Tiny’," should read: Animal is oriented with head facing upper right corner of the frame. 0:00–1:06| Quiescence (sleep-like state), 1:07–2:09| Sleep-like state+CA (activation of chromatophores, movement of eyes beneath lids, small movements of arms, 2:10–2:45| Transitions in and out of arousal, 3:34-| Quiescence resumes.
The correct legend for Figure 4, Quiescence (sleep) deprivation in the cuttlefish Sepia officinalis," should read: Four sub-adult cuttlefish were sleep deprived for 48 hours by continuous visual stimulation via a computer monitor positioned beneath their aquarium. During the following 24 hour recovery period, there was an overall compensatory increase in quiescence as revealed by a main effect of condition (baseline rest vs. after rest deprivation) in a 2 way ANOVA (Time and Condition as main factors): Condition: F = 6.3, p<0.013, Time: F = 9.6 p<0.001, interaction: F = 1.3, p = 0.18). Data are hourly mean (± std. deviation) behavioral scores.
