Full description

The study focused on locations in Marmion Lagoon in south-western Australia (31º49.4 S, 115º02.5 E) Five nearshore reefs: South Lumps, Whitfords Rock, The Lumps, Cow Rock and Wreck Rock (Table 1) were sampled. All sites were sampled in summer and autumn (January 2007 to April 2008) during calm conditions. Sponges and ascidians at each site were chosen haphazardly. Organisms on top of the reefs and reef walls were sampled and filtration rates measured.

The tube diameter was chosen to correspond closely to the osculum or exhaling syphon to account for filtering rate of the entire aperture or the organism.
