195 Feather stars or comatulids (Echinodermata, Crinoidea) are widespread in the subtidal zone of the World Ocean, while they reach the greatest diversity in the coral reefs of IndooWest Pacific [1]. Their sessile mode of life and low mobility presupposes that comatt ulids have different protective adaptations that allow survival in ecosystems with tight(More)
The host preference of the symbiotic gastropods Annulobalcis albus, Annulobalcis vinarius and Annulobalcis maculatus in the family Eulimidae for their crinoid hosts was studied experimentally. Y-tubes of plexiglas allowed us to investigate the effect of chemical factors. Sea-water from aquaria containing different crinoids, or similar sea-water from aquaria(More)
It is generally considered that symbiotic organisms colonize their hosts during their early stages of development. The main goals of the present study were to assess whether post-settled (juvenile and adult) symbionts were able to colonize comatulid crinoids, and whether a hosts’ spatial distribution may influence the colonization pattern through a series(More)
The symbiotic assemblage associated with the tropical sea urchin, Salmacis bicolor was studied in the An Thoi archipelago, Vietnam. Five species of macrosymbionts were found on the surface of this echinoid host, including the polychaete, Ophiodromus sp. 3 (Hesionidae), gastropod, Vitreobalcis sp. (Eulimidae), shrimp, Allopontonia iaini (Palaemonidae), crab,(More)
Physical and chemical (phase and chemical composition, dynamics of resorption, and strength properties), and biological (cytological compatibility and scaffold properties of the surface) properties of samples of scleractinium coral skeletons from aquacultures of three types and corresponding samples of natural coral skeletons (Pocillopora verrucosa,(More)
