Ophiothrix beds may consist of large adults and tiny, newly-settled juveniles, with animals of intermediate size living in nearby rock habitats or among sessile epifauna. The larvae may undertake a passive migration in areas such as the English Channel where there are strong water flow rates (Davoult, Mean disk diameter can decrease by up to 20 % during gamete production (Davoult, Although the species is gonochoristic Davoult, Recruitment success is heavily dependent on environmental conditions including temperature and food availability.
