            flatworm awaiting identification*

 Where 
            seen? Ah choo!! 
            Did someone just sneeze?! Resembling mobile phlegm, this flesh-coloured 
            flatworm is sometimes seen on our Southern shores. On rocky shore 
            boulders and under stones near the high water mark. It 
            moves rapidly and changing shape from nearly circular to elongated 
            as it slithers rapidly.
 
 Features: 6-10cm. This large, 
            rather fleshy flatworm is usually a uniformly pinkish or greyish beige, 
            with a very smooth body surface. Sometimes slightly translucent with 
            its internal parts visible. It does not have obvious pseudotentacles. 
            It seems to eat rather large prey for a flatworm and is sometimes 
            seen with alarmingly large lumps in the body.
