This small redfish does not grow as big as its deep sea relative, S. marinus. It rarely reach a length of 25 cm. The eyes are big, the body color red. On the gill covers there are five pointed spines, directed backwards. The members of the Sebastes genus give birth to living offspring during the summer months.
It prefers rocky bottoms, close to shore, on depths ranging from 10 to 150 metres.
It is widespread in the North-East Atlantic Ocean from Kattegat to Finnmark, Norway. It is also registered around the British Isles, the Shetlands, Faroes and Iceland. It is sporadically seen on Greenland.
