Short description आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण): 15 - 16; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 10-11; गुदा कांटा 3; ऐनल सौफट रेज़: 7 - 8. Diagnosis: lower pharyngeal jaw robust, with a large, triangular (not heart-shaped) dentigerous plate, covered with stout, sparsely arrayed teeth; oral dentition coarse; outer row teeth stout bicuspids (Ref. 26738, 81260). Anterior rakers not markedly reduced in size; snout acute (Ref. 81260). Ventral margin of lower lip smooth; 10-12 slender gill rakers (Ref. 26738, 81260). Ratio of lower jaw length to lower jaw width > 1 (Ref. 81260). 1-2 inner rows of teeth on both jaws (Ref. 26738, 81260).

Feeds primarily on vegetative matter (preferably algae), but also takes detritus, insects, diatoms and small amounts of sponges (Ref. 52307). A dwarf species, with females reaching sexual maturity at 25 mm SL, making this the smallest tilapiine known (Ref. 26738, 52307). The number of eggs produced is accordingly small, with 10-20 eggs usually deposited, preferably in shallow water on various substrates; large colonies composed of many pairs have been observed (Ref. 52307). Pair-bonding, open (Ref. 52307) substratum brooder (Ref. 52307, 81260), with both parents guarding the brood and fry (Ref. 52307).

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=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.1 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
