STUDIES ON LIGIA OCEANICA. 677 A general idea of the musculature will be obtained from Text-Figure 1. On the ventral surface are muscles attached to the ventro-lateral walls of the gut and running towards the middle line, where they meet and form a sheath (m.s.) to the structure lying immediately above.
The dynamics and life history of an isolated population of Ligia oceanica (L. ) inhabiting a sea-wall exposed to moderate wave action have been studied over a period of three years. Sex ratio, size at maturity, growth, breeding phenology, size and age structure, population density and size, female breeding size, fecundity regression and broodpouch mortality have been determined.
