Selective uptake of prokaryotic picoplankton (<2
μm) by a demosponge (
Callyspongia sp.), and carbon flux through this process, were examined for the first time in the oligotrophic coastal waters of southwestern Australia, where sponge abundance and biodiversity ranks among the highest in the world. Water sampling and flow rate measurements were conducted over five sampling occasions following the InEx method of Yahel et al. (2005), with heterotrophic bacteria and autotrophic
Synechococcus cyanobacteria identified and enumerated by flow cytometry.
Callyspongia sp. demonstrated high filtration efficiencies, particularly for high DNA (HDNA) bacteria (up to 85.3% in summer 2008) and
Synechococcus (up to 91.1% in autumn 2007), however efficiency varied non-uniformly with time and food type (
p
<
0.01). Overall filtration efficiency for
Synechococcus (86.6
±
6.3%; mean ± s.d.) was always significantly higher (
p
<
0.05) than for low DNA (LDNA) bacteria (40
±
17.2%), except during winter 2007 (
p
=
0.14) when ambient
Synechococcus concentrations were lowest. When compared to ambient abundances of the different food types,
Callyspongia sp. exhibited consistently negative selectivity for LDNA bacteria and positive selectivity for
Synechococcus, while HDNA bacteria was generally a neutral or positive selection. The total carbon removal rate (sum of all prokaryotic picoplankton cells), calculated on a per unit area basis, varied significantly with time (
