Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 7; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11; गुदा कांटा: 1; ऐनल सौफट रेज़: 11. This species differs from other congeners in having the following characters: 11 segmented rays on second dorsal fin; 33-35 longitudinal scale count; no predorsal scales; 11-12 transverse scale count from origin of second dorsal fin backward and downward to anal-fin base; naked pectoral-fin base; third spine of first dorsal fin longest, slightly elongate and filamentous; sensory-papillae row comprising four sensory papillae; a deep trough along posterior margin of eyes (Fig. 5B); first dorsal fin with numerous minute scattered yellow spots and no yellow submarginal lines; four faint brownish (tinged with yellow) mid-lateral blotches (rather than saddle-like bars) on body (Ref. 75057).

Occurs in coarse sandy bottom around rubble area, and found to be symbiotically associated with the alpheid shrimps (Ref. 75057).

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=0.00955 (0.00355 - 0.02566), b=3.03 (2.80 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.3 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).
