This species also feeds by tentacle flicking, in which each tentacle is slowly bent in to approximately its length, then slowly bent back out. By using tentacle flicking in conjunction with ciliary action, this species is able to concentrate particles into a bolus that is then directed towards the mouth. The food bolus is maneuvered around the mouth, and the polypide eventually retracts into the zooid, taking the bolus with it. S. sibogae is typically found as tiny encrustations on Syringodium and other seagrasses, algae, and the roots of hydroids. Seagrasses as well as floating macroalgae , provide support for bryozoan colonies.
Bryozoans are ecologically important in the Indian River Lagoon due to their feeding method.
As suspension feeders, they act as living filters in the marine environment.
