Locomotion of marine invertebrate larvae: a review
Marine invertebrate larvae swim by using cilia or muscles, or a combination of these. The effectiveness of cilia as locomotory organelles diminishes with increasing body size above 1 mm. Thus, larvae… Expand
Kinetics of Fertilization in the Sea Urchin Strongylocentrotus franciscanus: Interaction of Gamete Dilution, Age, and Contact Time.
Determining fertilization success of free spawning organisms in the field requires knowledge of how eggs and sperm interact under varying encounter frequencies and durations. In the laboratory, we… Expand
How Distribution and Abundance Influence Fertilization Success in the Sea Urchin Strongylocentotus Franciscanus
Many organisms reproduce by releasing gametes into the environment. How- ever, very little is known about what proportion of released eggs become fertilized. We examined the influence of spawning… Expand
Development and metamorphosis of the planktotrophic larvae of Rostanga pulchra (Mollusca: Nudibranchia)
Rostanga pulchra MacFarland, a small (1 to 2 cm) dorid nudibranch, lays an average of 7000 eggs in the laboratory during a period of 30 days in the summer. The veligers hatch 15 to 16 days after… Expand
Fine structure of Sertoli cells in three marine snails with a discussion on the functional morphology of Sertoli cells in general
SummaryThe fine structure of Sertoli cells in three marine prosobranch molluscs has been studied with light- and electron microscopy. Sertoli cells of prosobranchs are modified columnar epithelial… Expand

Development, settling behaviour, metamorphosis and pentacrinoid feeding and growth of the feather star Florometra serratissima
Embryonic development of the northeastern Pacific feather star Florometra serratissima takes place within a ridged fertilization membrane. Cleavage is radial, resulting in a coeloblastula, and… Expand
Fecundity and egg size are mediated by food quality in the polychaete worm Capitella sp.
Abstract Fecundity, egg size, and energetic investment·egg −1 were studied in two populations of Capitella sp.: one population inhabited an intertidal mudflat and fed on detritus and the other… Expand
Mating behaviour and reproductive cycle of Archaster typicus (Echinodermata: Asteroidea)
This study examines the reproductive cycle, the mechanism of male-on-female pairing behavior and the spawning behavior of Archaster typicus Müller et Troschel. Field studies were conducted in the… Expand
