Краткое описание определительные ключи | морфология | морфометрия

членистые (мягкие) лучи спинного плавника (общее число) : 11. Distinguished readily from all congeners including the sympatric Odontostilbe pulchra and Odontostilbe pao by its anterior position of the adipose fin, at vertical through last 2nd or 3rd anal-fin ray insertions. Can be further differentiated from Odontostilbe pulchra by a group of morphometric characters in males: snout pointed and longer 24.1-26.9% HL (vs. short and blunt in Odontostilbe pulchra, 18.0-26.0% HL); shorter pectoral-fin length 20.9-23.5% SL (vs. 21.3-26.4% SL); smaller anal-fin base 24.9-26.8% SL (vs. 26.0-31.4% SL); shorter caudal peduncle length 11.5- 13.0% SL (vs. 12.5-16.0% SL) ; longer snout-pelvic fin origin distance 45.1-48.7% SL (vs. 42.3-47.9% SL); and longer snout-anal fin origin distance 63.7-68.6% SL (vs. 58.6-64.0% SL). Furthermore, mature males have hooks on 1st to 6th-7th anal-fin rays (vs. hooks on 1st to 22nd anal-fin branched rays in Odontostilbe pulchra). Mature males usually have the 2nd unbranched dorsal-fin ray elongate, not present in Odontostilbe pulchra. Females and immature specimens, and not well-developed males can be differentiated from Odontostilbe pulchra by the following features: maxillary teeth 3-4, mostly 3 (vs. 2-3, mostly 2 in Odontostilbe pulchra; lateral line with 36 scales, one specimen 35 (vs. 33-37, mostly 34-35). Differs also from Odontostilbe fugitiva by its gill rakers counts on lower branch, averaging 11 (vs. usually 12) (Ref. 75063).

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=0.00891 (0.00388 - 0.02045), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.5   ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref. 120179):  высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
