A Mirror Dory, Zenopsis nebulosa, from a seamount in the Tasman Sea, May 2003. Source: Robin McPhee & Mark McGrouther / NORFANZ Founding Parties. License: All rights reserved
An extremely compressed silvery-grey dory with a large, faint, midlateral blotch, blackish membranes on the spinous dorsal fin, pelvic fins and outer part of the caudal fin. Juveniles are silver with many indistinct, dark irregular blotches of varying sizes on the sides, spinous dorsal-fin membrane and pelvic fins.
The Mirror Dory lacks scales except for tiny lateral-line scales, and has a series of large bucklers along the bases of the dorsal and anal fins, and along the ventral midline from in front of the anal-fin origin.

Head very large; eyes of relatively small to moderate size; mouth very large and protrusible, upper jaw length greater than snout; small canine teeth present in jaws and on vomer. Scales absent except for those supporting lateral line; lateral line arched anteriorly; large bony bucklers present at bases of dorsal and anal fins (10-14 at dorsal-fin base, 6-9 at anal-fin base); bucklers also present between isthmus and anal-fin origin. Dorsal fin in two parts, comprising centrally placed spinous first dorsal with base of moderate length, attached by low membrane to long based and low soft dorsal; spines relatively slender, those of first dorsal elongate, longest approximately equal to head length with interspinous membrane produced into filaments beyond each spine; anal fin similar to and opposite second dorsal fin, spines prominent; caudal fin large, truncate. Pectoral fins small, rounded. Pelvic fins elongate, extending to just before or beyond anal-fin origin. |
