Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 18 - 35; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 64 - 73; गुदा कांटा: 2; ऐनल सौफट रेज़: 67 - 80; जानवरों की रीड़ का जोड़: 95 - 96. Diagnosis: Anterior nostril in the form of a short tentacle; snout produced as a fleshy appendage (Ref. 34290). Number of dorsal-fin spines 18-35; anal fin with 2 separate spines (Ref. 34290, 123814). Colour extremely variable, ground colour brown with a variable reticulated and blotched pattern (Ref. 34290).

Mainly riverine species, but also occurs in lakes near river mouths and in vegetated fringes and in swamps (Ref. 80296). Also found in rapids where it hides among rocks (Ref. 85214). Essentially a sedentary fish, nocturnal and usually waiting for its prey to swim or drift within range whereupon fish will dart out of its shelter to seize it (Ref. 89002). Feeds on aquatic insect larvae (Ref. 80296), lithophilic insects (Ref. 12526), fish (Ref. 13624, 27292), shrimps (Ref. 246, 80296), oligochetes and occasionally vegetable matter (Ref. 80296, 89002). Breeds during flood season, in inundated areas (Ref. 80296). Eggs yellow and large, probably spawned among water weeds (Ref. 89002).

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=0.00257 (0.00122 - 0.00544), b=2.97 (2.79 - 3.15), 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.

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).
