The mechanism of action of the hatching substance released by Ilyanassa obsoleta embryos was examined by studying the sequential ultrastructural and biochemical changes that occur in the egg capsule plug as it is dissolved during hatching. When relea

Oyster larvae exposed to solutions of NH4Cl exhibit stereotypical settlement behavior similar to that which normally precedes cementation and metamorpho- sis. Un-ionized ammonia is the active chemical species. At pH = 8.0, the threshold concentration

Dissolved chemical inducers of settlement behavior of veliger larvae of the oysterCrassostrea gigas are found in supernatants of both pigmented species of bacteria (Alteromonas colwelliana, Vibrio cholerae strain HTX) as well as nonpigmented bacteria

Lithophaga date mussels from three species (L. lessepsiana, L. simplex and L. purpurea) were removed from their stony coral hosts in the Red Sea at Eilat, Israel. Spawning, observed in the laboratory on several occa- sions during 1987-1988, appeared

Lithophaga simplex (Bivalvia:Mytilidae) inhabits only two species of live corals in the Red Sea: Astreopora myriophthalma (Lamarck) and Goniastrea pectinata (Ehrenberg). Larvae from mussels originating from both of these corals were offered a variety

Veliger larvae of the oysterCrassostrea gigas (Thunberg) responded to unknown dissolved chemical inducers found in supernatants of cultures of the bacteriaAlteromonas colwelliana andVibrio cholerae. The response, which was similar to that seen when l

The temporal relationship between the onset of behavioral and morphogenetic competence was determined inCrassostrea gigas (Thunberg) larvae by exposure to appropriate chemical inducers during development. Larvae exhibited settlement behavior in respo

ABSTRi@CT Oyster larvae and spat of varying ages were homogenized and analyzed for cate cholamine content using high-performance liquid chromatography with electro chemical detection. Norepinephrine (NE) and dopamine (DA) were found in appre ciable q

Ciliary feeding by tornariae of Ptychodera flava (Eschholtz) and other tornariae from the plankton is compared with Garstang's (1939) account of feeding by these larvae, which account contains errors, and with ciliary feeding by echinoderm larvae. So

Oyster larvae were treated with selected neuroactive compounds and structural analogs to test the ability of these drugs to induce settlement and metamorphosis. L -3,4-Dihydroxyphenylalanine ( L -DOPA) induced both settlement (a behavioral response)
