Description

provided by World Register of Marine Species
The dorsal side is covered with overlapping scales (elytra). The shape of the elytra varies from round, reniform to cordiform depending on the body part. They are usually covered with papillae. The body is long (up to 200 mm) and has numerous segments; dorsal side is convex, ventral side is flattened. The dorsal side has a light grey, yellowish or brownish colour with red to black transverse bands.

Distribution

provided by World Register of Marine Species
Sthenelais boa has a limited distribution on the Belgian part of the North Sea: in both periods the species was only observed in the near-coastal zone, with the exception of the eastern coastal zone. Whereas S. boa was only found in low densities in the 1976-1986 period (maximum 12 ind./m2) densities up to 250 ind./m2 were recorded in the 1994-2001 period.

Habitat

provided by World Register of Marine Species
Sthenelais boa prefers fine-grained sediments with a median grain size of 150 to 250 µm. The species is nevertheless also found in finer and coarser sediments (up to 500 µm). Preference is given to sediments that are to some extent enriched with mud (maximum 40%). The highest relative occurrence (60%) is reached in sediments with a mud content of 10-20%.
