Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 10; Afterflossenstacheln 0; Afterflossenweichstrahlen: 11 - 12. Diagnosis: body elongated, 5.66-6 times longer than deep (Ref. 45616). Body depth equal to head length, the latter 5.33 times in total length; eye lateral, visible from below as well as from above, its diameter 3.33 times in head length; sides and lower surface of head with conical horny tubercles; males with cupshaped apparatus on operculum, much larger than eye, and followed, on scapular region, by a large lamellar pad (18-19 lamellae) (Ref. 1869). Dorsal fin with 7 branched rays (Ref. 1880), originating well beyond vertical of base of pelvic fins (Ref. 1869, 45616). Anal fin with 8-9 branched rays (Ref. 1880). Caudal fin deeply notched, crescentic; pale brownish above, yellowish beneath, with scattered dark brown dots and a series of round blackish spots, connected by a dark brown lateral band, just above the lateral line; fins uniform whitish (Ref. 1869). A black dot at base of pelvic fins (Ref. 1880).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
