  • littorina saxatilis life cycle

    However, some tiny tropical species live for less than 1 year and their life cycle takes only about 3 months (Hopkin and Read, 1992). 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.

Collections of L. saxatilis were made from the Whitstable shore on the southern side of the Thames estuary. Encyclopedia of Life; Littorina saxatilis. Littorina saxatalis, the rough periwinkle, is a species of small sea snail native to the Atlantic ocean. The planktonic larval stage is long (up to 6 weeks) although larvae do tend to remain in waters close to the shore. L. littorea is oviparous, reproducing annually with internal fertilization of egg capsules that are then shed directly into the sea, leading to a planktotrophic larval development time of four to seven weeks. Isle of Man historical wildlife records 1995 to 1999. (2010). "Morphological differentiation and genetic cohesiveness over a micro-environmental gradient in the marine snail.

In organisms encountering predictable environments, fixed development is expected, whereas in organisms that cannot predict their future environment, phenotypic plasticity would be optimal to increase local adaptation. [5] This ecotype displays a larger and more robust shell to resist the attack from predators such as crabs, and a smaller shell aperture in order to reduce the desiccation due to high sunshine exposure.
