Ecology
General:
Ectopleura viridis has both a sessile hydroid stage and a free-swimming medusa stage (Mayer 1910; Schuchert 2003). The appears to have an affinity for man-made structures, occurring on floats and fish traps in New Britain (Mayer 1910) and on mooring buoys in Apra Harbor (Kirkendale and Calder 2003), but it is also known from corals, sponges, and crabs (Schuchert 2003).
Food:
Zooplankton, epibenthos
Trophic Status:
Suspension Feeder
