Maude E. Carmel MD, FRCSCm and mature. This life cycle (‘amphidromy’) is common in tropical islands; the upstream migration may occur in large aggregations. Some nerites spend all their lives in freshwater; here one embryo inside each capsule develops faster, canibalises its siblings, develops into a miniature adult and hat

Amy D. Dobberfuhl MD,Elise J. B. De MDom which they expel intruders and weed out other algae; in some, sticky mucous trails trap algae and stimulate algal growth so limpets retracing their trails capitalise on food-enhancing mucus. Primitive limpets respire through a gill, others through a cordon of flaps hanging from the mantle around
