Description
Size: 10-30 mm. by 8-10 mm.

Color: Whitish-grey

Sternaspis scutata is a stout burrowing worm, with a leathery texture. The body is divided into 20-22 segments, the first seven forming the anterior region, the remainder forming the posterior region. The anterior region is much smaller and narrower than the posterior region into which it can withdraw. The head is reduced and bears a small translucent rounded prostomium above the mouth. The first segment behind the head forms a peristomium that is covered by short papillae. The 2nd-4th segments are each marked by a row of dark spines on either side. Two tubular papillae mark the division between the anterior and posterior region at the 7th and 8th segments. The remaining posterior segments are covered on the ventral surface by a pair of brown stiff plates that both bear a bundle of 15-17 chaetae that are much longer and more noticeable than the notochaetae. Numerous long, slender, occasionally spiralled gills extend from the posterior.Body sausage like, narrowed in the middle, expanding at both ends. The anterior segments often retracted into the following ones. Prostomium reduced to a mere small knob. Shield plate divided into two unequal parts by a slanting line and marked with ridges and striea.
