Dorsale stekels (totaal) : 6; Dorsale zachte stralen (totaal) : 12 - 13; Anale zachte stralen: 13; Wervels: 26. This species is distinguished from its congeners in the following set of characters: D VI,12-13 segmented rays; A 13 segmented rays; pectoral-fin rays 14-15, long pectoral fin, reaching past end of pelvic fins, its length 20-22% SL; caudal-fin with 8+7 segmented rays and long, 21-23% SL; large head 29-30% SL; long snout 12-16% head length; jaws are subequal, posterior end of jaws reaching posteriorly to or beyond vertical at anterior oculoscapular canal pore F?; tip of upper lip without a small anteriorly directed skin projection; reduced longitudinal pattern of sensory papillae rows; rounded caudal fin (Ref. 93255).
Inhabits muddy bottoms of estuarine at 0.5-2 m depth; living in burrows dug by invertebrates. During breeding season, males swim vertically above the burrows and display to females (Ref. 93255).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
