The sandhopper Talitrus saltator has an endogenous activity rhythm with a circadian periodicity. It is well known for its ability to compensate for the apparent movement of the sun during its migrations along the sea-land axis of the beach. Both chronometric mechanisms are entrained by the natural LD photoperiod. Using actographic recordings and tests of solar orientation of individuals kept under an LD 12:12 clock-shifted cycle, after 1-13 days of treatment, we demonstrate that the timing mechanism of activity rhythm and the chronometric mechanism underlying the sun compass are the same.
