Ecology of Spirobranchus giganteus

Main Ref.	Rowley, S., 2008
Remarks	A dioecious filter feeder that is often mistaken to be a boring species. Larvae actually settles on exposed corals skeleton and extend their tubes toward the living tissue, which subsequently obscures the tube. Simultaneous spawning of male and female species and its host corals (Orbicella annularis, O. faveolata, O. franksi, Montastraea cavernosa, Pseudodiploria strigosa), occurred in the evening during slack neap tides with nominal wind and wave action. Such conditions minimize gamete distribution by water turbulence and wave action, increasing the chances of fertilization (Ref. 81049). Part of fouling communities attached to raft frames in mariculture zones (Ref. 127121).
