Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 2; Spine anali: 0. Snout narrow, bluntly rounded, almost entirely bare, with a small inconspicuous scute at its tip. Suborbital ridge rounded and shallow in cross section, without scute-like scales. Cephalic pores of the lateralis system indistinct, but sensory papillae densely dispersed over the head. Pyloric caeca 25 to 37. Body scales small, easily shed, mostly without spinules, but some with slanting conical spinules. Overall color is Grayish brown with violet tinged; abdominal region, gill membranes and gill cover blackish; oral and branchial cavities and fins dusky to blackish.
Caught as a by-catch of trawlers fishing for Dover sole but of no commercial value (Ref. 9315). Problems with taxonomy. Shallowest depth record from Ref. 37930.
