Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 12; Dorsale zachte stralen (totaal) : 7; Anale stekels: 3; Anale zachte stralen: 5 - 6. Body light brown, irregularly blotched with darker brown; a broad dark band across interorbital, continuing as a bar below eye and another band from origin of dorsal fin to eye. Dorsal fin pale with a large dark brown blotch in middle of the fin, usually between 6th and 9th spines; other irregular blotches especially posteriorly. Caudal fin whitish with faint small dark spots. No scales. Body depth 2.45-3.1 in SL. Lacrimal with 2 spines, a short ventral one and a large posterior one that extends to below center of eye. Preopercle with a large spine in line with suborbital ridge; the second spine, lower, very small and blunt. Origin of dorsal fin above rear edge of eye; a broad space between 3rd and 4th dorsal spines, the associated membrane deeply incised, nearly dividing the dorsal into 2 fins. Caudal fin truncate, slightly rounded when spread (Ref. 11441).
Found inshore on sandy bottoms, often in bays.

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00780 - 0.04657), b=3.03 (2.82 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
