Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 24; ऐनल सौफट रेज़: 39; जानवरों की रीड़ का जोड़: 69. A single, ovoid terminal bulb 0.8-1.8% SL, with nipple-like distal protuberance. Barbel 41-58% SL. A single but complex terminal filament with 2 long branches arising together near its base, followed by 1-5 large bulblets, then by 2 shortest branches arising together, each usually with a prominent large bulblet; all branches and the main filament with numerous, prominent small bulblets. Filament length 12% SL. Axis of stem lightly or unpigmented; a prominent, wide, black circle forming a cap at base of terminal bulb. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin usually 7, sometimes 8. Anterior margin of fleshy orbit with a distinct slender pedicel extending posteriorly over the eye (Ref. 11333).

Mesopelagic (Ref. 58302). Environment and depth range needs to be checked.

Estimates based on models

Preferred temperature (Ref. 123201): 1.6 - 3, mean 1.7 °C (based on 57 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.8 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Assuming tmax>3).

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