in width. The body is more or less cylindrical with rounded anterior and posterior ends, of a dirty­white colour (preserved) and without encrusting foreign bodies. Mouth ventral, encompassed by 20 prominent brown tentacles, which often are retracted and thus difficult to make out. The anus is ventral in position, enclosed in an inconspicuous pygal furrow. Filiform tube feet, lacking a sucking disc, are found sparsely scattered on the ventral side (often visible as small brown spots) but could not be detected dorsally. The body wall is thick and rugose.
