Dorsal spines (total): 7; Dorsal soft rays (total): 14 - 15; Anal spines: 2; Anal soft rays: 44 - 47.

Adults inhabit mangrove-nipa swamps, brackish estuaries and slow-flowing turbid rivers. Feed on small fishes, shrimps and crayfish. The male carries the eggs around like a bunch of grapes attached to a hook on the head, called forehead brooding (Ref. 36739, 44894). Esteemed table fish (Ref. 2158).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Males carry eggs in clusters or balls attached to a hook on the head, known as 'forehead brooding'. This may be an adaptation to environments with low oxygen and high turbidity (Ref. 36739).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01380 (0.00575 - 0.03313), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.63 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=1-2;).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).

Price category (Ref. 80766): Unknown.
