Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9 - 11; गुदा कांटा: 0; ऐनल सौफट रेज़: 8 - 11; जानवरों की रीड़ का जोड़: 29 - 30. Pink-white. No eyes (vestigial eye tissues under skin). Extremely small pelvic fins (rarely absent). Large, broad head. Caudal fin with 4-6 rows of papillae; 11-13 branched caudal rays.

Blind and depigmented. Despite the lack of eyes it does respond to light and moves away from it (scotophilia). Inhabits subterranean water or caves which have consolidated mud-rock substrates in shoals and silt-sand substrates in pools but is more often found in caves with uniform silt-sand substrates (Ref. 34868). Has low reproduction rate and broods eggs in gill cavity for up to 4-5 months (Ref. 557; 34868; 27795). Can live for 2 years without food because of low metabolic rate (Ref. 5326). Top predator.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6338 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.39 se; based on food items.

Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (K=0.20; low reproductive rate (Refs. 34868; 27795).).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).
