Fig. 4From: Feeding cessation alters host morphology and bacterial communities in the ascidian Pseudodistoma crucigaster Scanning electron micrographs of the colony surface of the ascidian Pseudodistoma crugicagster. Photos show a the surface of an active colony with two siphonal apertures (asterisks), and b the surface of a non-filtering colony featuring some microorganisms (arrows point to diatoms, arrowheads indicate some bacteria).
