Short description आकृति विज्ञान | मौरफोमैटरिक्स

ऐनल सौफट रेज़: 196 - 233. Can be distinguished by the following combination of features: elongated caudal filament reaching up to 45% TL in reproductive males; 6-11 wide, evenly spaced saddles of pigment over dorsum connecting to lateral bands; mesocoracoid bone present; large eye, 15.5-19.2% HL; short abdomen, usually with 12 pre-caudal vertebrae (range 11-13); poorly ossified third and fourth (outermost) branchiostegal rays, much enlarged distally, covering distal portions of the first two branchiostegal rays externally and contributing to bulbous appearance of opercular region (Ref. 81045).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Inhabits clear, shallow, standing water in open savanna, or savanna mixed with stands of Mauritia palm. Collected in the vegetation along the banks of small pools fed by steams. Occurs inactive during the day among the stems and roots of emergent grasses and sedges. Encountered only in very low conductivity water (<25 μS/cm) where it usually co-inhabits with Brachyhypopomus brevirostris. The electric organ discharge waveform is biphasic, 0.9-1.6 milliseconds in duration, and the pulse rate ranges from 20 to 80 Hz (Ref. 81045).

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=0.00380 (0.00145 - 0.00994), b=3.06 (2.83 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
