Second body clock discovered in the speckled sea louse

Separate timing mechanism presents an exciting new perspective on how organisms define biological time

The diminutive speckled sea louse (Eurydice pulchra) boasts two body clocks, one for night and day and another for the ebb and flow of the tide, according to research published today, Thursday 26 September.

Writing in the journal Current Biology, researchers from Aberystwyth, Bangor, Cambridge and Leicester Universities have confirmed the existence for the first time of a distinct and independent circatidal body clock that follows the 12.4 hour cycle of the tide.
