Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 13 - 19; Raggi dorsali molli (totale) : 53; Raggi anali molli: 49; Vertebre: 75. Distinguishable by its dorsal spine count of 13-19 and a series of 3-6 conspicuous ocelli along the base of the soft dorsal fin (Ref. 27732). The ocelli along the base of the dorsal fin are much larger than those in M. aral and the dorsal and caudal fins lack the fine striations seen in M. aral and M. meklongensis (Ref. 39392). Dorsal, caudal and anal fins not fused (Ref. 43281).

Found at bottom depths in slow-moving or standing waters. Often lies buried in the silt, sand, or fine gravel with only a portion of its head protruding from the bottom (Ref. 12693). Enters flooded forest (Ref. 9497). Emerges at dusk to forage for food. Feeds on benthic insect larvae, crustaceans, and worms (Ref. 12693). Marketed fresh and often seen in the aquarium trade (Ref. 12693).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00282 (0.00130 - 0.00610), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.40 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100).

Price category (Ref. 80766): Unknown.
