Base plate mechanics of the barnacle Balanus amphitrite (=Amphibalanus amphitrite).
The mechanical properties of barnacle base plates were measured using a punch test apparatus, with the purpose of examining the effect that the base plate flexural rigidity may have on adhesion mechanics. Base plate compliance was measured for 43 Balanus amphitrite (=Amphibalanus amphitrite) barnacles. Compliance measurements were used to determine flexural rigidity (assuming a fixed-edge circu...
متن کاملSpectral Sensitivity of the Barnacle, Balanus amphitrite
The extracellular ocellar potential was used to evaluate the spectral sensitivity of the ocellus of the barnacle, Balanus amphitrite. Maximum relative sensitivity was at 530-540 nm. Studies with chromatic adapting lights suggest that the receptors contain a single photopigment. The spectra were relatively broader in the dark as compared to the light-adapted state. This effect was shown to be du...
متن کاملMetamorphosis in the Cirripede Crustacean Balanus amphitrite
Stalked and acorn barnacles (Cirripedia Thoracica) have a complex life cycle that includes a free-swimming nauplius larva, a cypris larva and a permanently attached sessile juvenile and adult barnacle. The barnacle cyprid is among the most highly specialized of marine invertebrate larvae and its settlement biology has been intensively studied. By contrast, surprisingly few papers have dealt wit...
متن کاملLarval metamorphosis of the barnacle Amphibalanus amphitrite under mono and mixed algal diet
Barnacles are one of the dominant macrofouling organisms found in the intertidal region throughout the word. In this study, the effects of mono and mixed algal diet (Chaetoceros calcitrans, C. muelleri, Isochrysis galbana, Tetraselmis suecica and Chlorella vulgaris) on the larval metamorphosis of the barnacle Amphibalanus amphitrite were evaluated. Larvae obtained from A. amphitrite were cultur...
متن کاملInfluence of delayed metamorphosis on survival and growth of juvenile barnacles <Emphasis Type="Italic">Balanus amphitrite</Emphasis>
Competent cyprid larvae of the barnacle Balanus amphitrite Darwin were prevented from metamorphosing in the laboratory for 3 or 5 d using three different techniques (holding at low temperature, crowding, and detaining on a silanized surface). We then assessed the effects of prolonging larval life on post-metamorphic growth and survival, in comparison with control individuals that metamorphosed ...
