The short anterior tentacles (1:), which can be retracted by inversion, are close to the mouth. When not feeding, the mouth is concealed behind a pair of lobe-like lips (2:) that open laterally, and the lips are flanked by lobes of the head (3:).
In these images the U shape feature (4:) is the edge of the mucus layer under the head and foot.
The radula was not extended in these photographs as the glass was devoid of food, so not worth expending energy on.
