Extract

More than half of the species of British prosobranchs living intertidally have planktonic larvae. Settlement involves a positive response to certain factors which results in a speedy loss of structures fulfilling larval needs and the introduction of others associated with locomotion and feeding on the sea-bed (Fretter, 1972). Unless this response relates to the needs of the species, settlement could lead to mass mortality of larvae settling on unsuitable ground.
