Marbled flatworm
awaiting identification
updated Oct 2016

Where seen? This small flatworm is sometimes seen on Beige asicidians that are growing under rocks. So far, only seen on our northern shores.

Features: 1-3cm long. Body pale beige with dark markings, irregular dark stripe along the middle. Body edge with irregular dark finger-shaped patches and a fine narrow orange line cutting across the patches. When one flatworm was removed, there was a circular hole in the encrusting ascidian under it. Did the flatworm eat the ascidian?
