The species has an elongate body with a broad, bony armoured head shield and barbels, and reaches about 63 cm. It lives on muddy bottoms of shallow brackish water and also in the sea. Reproduction occurs around May and June; the female lays 20 to 30 very large eggs (10-12 mm), glued together in mucus, which the male broods in its mouth.
