Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 6 - 8; Spine anali: 1; Raggi anali molli: 6 - 7. Distinguished by the following characteristics: slender with compressed head and body; greatly enlarged jaws in adult males with lips distinctively broadened anteriorly and narrowed below eye; body with scale margins outlined forming reticulate pattern; dark band along mid-side of body; head with 4-6 curved oblique dark bands crossing cheek and small dark mark behind upper rear part of eye; variably sized black blotch on posterior part of first dorsal fin; second dorsal rays I,6-8; anal rays I,6-7; pectoral rays 15-18; longitudinal scales 22-25; TRB 7-8 1/2; predorsal scales 6-9 (Ref. 84480).

Adults inhabit sea and rivers (Ref. 419). Found in estuaries and lower (tidal) reaches of freshwater streams (Ref. 2847). Usually recorded from swift flowing streams, often described as cascades or cascade zone, above or below waterfalls, with solid rock, boulder and gravel substrate. A few sites consisted of mud and sand substrates and one was from a mangrove only 50 m from the shoreline. Gut content of one specimen from Palau contained insect remains and a few nematodes (Ref. 84480).

Estimates based on models

Preferred temperature (Ref. 115969): 27.4 - 29.4, mean 28.8 (based on 1088 cells).

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

Bayesian length-weight: a=0.00977 (0.00442 - 0.02163), b=3.05 (2.86 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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