More Info


Distribution

Endemic to southern Australia from Kangaroo Island and the Gulf St Vincent, South Australia, to Albany, Western Australia.

Features

Dorsal fin 70-80; Anal fin 60-67; Caudal fin 15-16; Pectoral fin 6-7; Pelvic fin 4; Lateral line scales 67-76.  
Body of moderate depth (36-40% SL), extremely compressed, of moderate length. Head small (17-22% SL);  eyes on right side of head, small (17-26% HL), separated by narrow scaly space;  snout produced slightly downward in front of mouth;  mouth small (upper jaw length 28-33% HL), strongly curved;  teeth tiny, in band only on blind side of each jaw; numerous small cirri anteriorly on blind side of head, reaching posteriorly only slightly past mouth; opercular margins edged with cirri, especially well developed on blind side.  
Scales very small, ctenoid on both sides, moderately firmly attached, covering all of head not covered by cirri; lateral line on both sides of body, nearly straight along centres of sides, curving upwards and forwards from back to front of head. 
Dorsal, anal and caudal fins broadly interconnected by membranes; dorsal fin arising above anterior rim of upper eye, without elongate anterior rays; caudal fin rounded. Pectoral fins very small, connected to opercular membranes, similar to one another in size and form. Pelvic fins with short bases, originating near anterior extent of chest, not attached to anal fin.

Size

Reaches a length of 150 mm. 

Colour

Eyed side dusky with 16-22 faintly darker parallel bands crossing body and base of caudal fin, bands of equal breadth or slightly narrower than interspaces and difficult to distinguish from interspaces; blind side pale. Dorsal and anal fins dusky to dark with narrow pale margins on both sides.

Fisheries

Taken as by-catch in commercial prawn trawls.

Similar Species

The Duskybanded Sole, Zebrias penescalaris differs from the similar Manyband Sole, Zebrias scalaris, in having fewer lateral-line scales (67-76, vs 79-86 in the Z. scalaris, one specimen with 74 scales), generally fewer dorsal-fin rays (70-76, vs 75-82 in Z. scalaris, one specimen of Z. penscalaris with 80 scales), and less definition in the body banding.

Etymology

The specific name penescalaris is from the Latin pene (= almost or near) and scalaris (= of a ladder) in reference to the close relationship of this species to the Manyband Sole, Zebrias scalaris.
