Blind datingmate finding in planktonic copepods. III. Hydromechanical communication in Acartia tonsa
Espen Bagøien1,2,*, Thomas Kiørboe1
ABSTRACT: Mate-finding behaviour in the marine copepod Acartia tonsa was examined by video analysis. A. tonsa appears to depend on hydromechanical signals in the location of mates, detected at distances of up to 5 or 7 mm. Series of up to 7 or 8 synchronised hops in closely situated individuals, interpreted as an expression of hydromechanical communication or assessment of a potential partner, often concluded with mating. We use previously published models of hydrodynamic signalling to explain the observed behaviour and extrapolate the results to other species.
