Abstract
Spermatozoids of the intertidal seaweed Ascophyllum nodosum (Fucales, Phaeophyceae) are attracted to eggs prior to fertilization. The attractant has been isolated and its structure identified as 1(3 E ,5 Z ,8 Z )-undecatetraene (finavarrene). The relation of finavarrene to sex hormones in other brown algae is discussed.Keywords
