Do Cuttlefish Dream of Electric Shrimp? A Natural History Note on Behavioral Quiescence Strategies in Wild European Cuttlefish ( Sepia officinalis )

Laboratory‐based ethological studies have identified highly structured sleep‐like and quiescent states in coleoid cephalopods. However, identifying these physiological states in wild populations remains challenging due to observer‐induced flight behaviors. Presented here are a secondary micro‐kinetic analysis of an unprovoked wild cohort of six sub‐adult European cuttlefish ( Sepia officinalis ) recorded continuously for 55 min in their natural habitat. Quantitative point‐process analysis of localized motor events revealed that micro‐somatic adjustments (low‐amplitude arm L1/R1 twitches, N = 64) are significantly clustered, exhibiting a median inter‐event interval of 2.08 s. First‐order Markov chain modeling demonstrates a highly structured behavioral transition network centered on a composite chromatic state (Mottled + Zebra Pattern composite), with a restricted probability (14.3%) of transitioning into absolute motor arrest (Mantle fin stop). While limited by sample size and a lack of physiological or electrophysiological metrics, these field observations provide a rare, non‐invasive behavioral baseline that mirrors the micro‐kinetic patterns reported in controlled laboratory sleep settings. We also provide verbal descriptions of quiescent states observed.
