Ectocarpene is the rearrangement product of pre-ectocarpene,^[1] the sexual attractant, or pheromone, found with several species of brown algae (Phaeophyceae). Ectocarpene has a fruity scent and can be sensed by humans when millions of algae gametes swarm the seawater and the females start emitting the substance's precursor to attract the male gametes.

All the double bonds are cis and the absolute configuration of the stereocenter is (S).^[1]
