Effects of Salinity on Embryonic and Early Larval Development of a Tropical Sea Urchin, Salmacis sphaeroides
Effects of salinity on fertilization, embryonic stage, and early larval development and growth performances of short-spined white sea urchin, Salmacis sphaeroides were conducted under a controlled laboratory condition. The experiment was carried out with seven salinity treatments (15, 20, 25, 30, 35, 40 and 45 PSU), each of which was triplicated. Significantly highest fertilization success was ...

متن کاملEmbryonic, Larval, and Early Juvenile Development of the Tropical Sea Urchin, Salmacis sphaeroides (Echinodermata: Echinoidea)
Salmacis sphaeroides (Linnaeus, 1758) is one of the regular echinoids, occuring in the warm Indo-West Pacific, including Johor Straits, between Malaysia and Singapore. In order to investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of S. sphaeroides in laboratory condition. Gametes were obtained from adult individuals by 0.5 M KCl injec...
متن کاملSea urchin feeding fronts
Sea urchin feeding fronts are a striking example of spatial pattern formation in an ecological system. If it is assumed that urchins are asocial, and that they move randomly, then the formation of these dense fronts is an apparent paradox. The key lies in observations that urchins move further in areas where their algal food is less plentiful. This naturally leads to the accumulation of urchins...
متن کاملEstimation of Biochemical Composition of Purple Sea Urchin (salmacis Virgulata, L.agassiz and Desor, 1846)
The proximate composition, fatty acids, minerals and vitamins contents of purple sea urchin (Salmacis virgulata) from the spine, viscera, test region of the S. virgulata analysed. Among the different tissues studied, a highest fat, and carbohydrate content of 39.56mg, 23.57mg and 21.94mg was recorded in the test region of the sea urchin which was collected in the Mudasalodai, Southeast coast of...
