soft rays: 5 - 8. Transverse scale rows: 10-13. Distinguished from all other family members by having 3 or less dorsal spines (versus 7 or more), 6-7 broad dark bars along flanks (versus 7 or more), 16-18 peduncle scale rows (versus 18-24).
Found on sand, clay, mud and/or limestone substrate commonly associated with rooted, submerged vegetation (Ref. 58011). Oviparous, eggs are deposited in aquatic vegetation, preferably on strands of Ceratophyllum sp. when available (Ref. 58020).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (tmax=1; Fec=65).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
