In normal reproduc-tive males the penis is 4-5 mm or more in length. Description. With seashell related information for expert and amateur collectors. Abstract. Ang Littorina saxatilis sakop sa kahenera nga Littorina, ug kabanay nga Littorinidae. the genus Littorina (Reid I990a) suggest that in the UpperPliocene at least two independentlin­ eages immigrated from the Pacific Ocean to the northern Atlantic, and led to the six recent spe­ cies ofLittorina in this area (Reid 1990b). We investigated variation in shell size and shape of marine snail species of the Littorina saxatilis complex (L. saxatilis, L. compressa and L. arcana) using geometric morphometric methods. Other articles where Littorina saxatilis is discussed: periwinkle: L. saxatilis, which lives high up on rocks and is often out of water for long periods of time, holds its embryos in a brood sac until the young are fully developed, at which time they emerge as tiny crawling replicas of the adult.
