Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 11; Rückenflossenweichstrahlen (insgesamt) : 18 - 21; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 9 - 12. Distinguished by the following characteristics: dark brown or violet-black body color, darker fins; oval body, compressed, depth contained 2.4-2.7 times in the standard length; head length 3.0-3.4 times in SL; distinctly convex dorsal head profile; nostrils subequal in juveniles, diameter of posterior nostrils twice that of anterior nostrils in 56 cm SL adults; small mouth, oblique, pair of short canines at front of each premaxilla (Ref. 89707).

An anti-tropical species. Occurs on rocky or soft (silty-sand or mud) bottoms. The young have been observed to feed on zooplankton in the water column; feeding of adults has not yet been discovered.

Estimates based on models

Preferred temperature (Ref. 123201): 17.9 - 25.7, mean 23.7 °C (based on 53 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00553 - 0.02385), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Generation time: 6.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).

Preiskategorie (Ref. 80766): Very high.
