Abstract Tidal cycles are known to affect the ecology of many marine animals, but logistical obstacles have discouraged behavioural studies on sea snakes in the wild.Here, we analyse a large dataset (1,445 observations of 126 individuals) to explore tidally-driven sensationnel brielle shifts in the behaviour of free-ranging turtle-headed sea snakes (Emydocephalus annulatus, Hydrophiinae) in the Baie des Citrons, New Caledonia.Snakes tended to move into newly-inundated areas with the rising tide, and became more active (e.

g.switched groovy mama ring from inactivity to mate-searching and courting) as water levels rose.However, the relative use of alternative habitat types was largely unaffected by tidal phase.
