Clés d'identification | Morphologie | Morphométrie
Vertèbres: 129 - 138. Head short and very broad. Body robust with inflatable stomach; with dark, mottled and blotched color pattern, and mostly with a dark median stripe on the belly. Labial furrows absent. Denticles large and widely spaced.
Body shape (shape guide): elongated; Cross section: flattened.
Found on the continental shelf from close inshore in shallow to deeper water. Oviparous, hatching at about 14 cm (Ref. 6871). Can expand itself with air or water. Caught by commercial bottom trawlers but of no use to fisheries at present.
