Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 8; Radios blandos dorsales (total) : 19 - 20; Radios blandos anales: 17 - 18. Head large and without spine; snout with nostril spine; eyes small and nearer to tip of snout; mouth large, upper jaw slightly projected and reaching rear edge of eyes; gill opening large, pseudobranch present and gill rakers small; scales absent but with small knobbles on body.

Adults live at the mouths of rivers that fall into the seas along the coasts of the warmly temperate zone of East Asia. Carnivore. Can grow to 12-14 cm long and becomes sexually mature in one year (Ref. 45563).

Estimates based on models

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

Bayesian length-weight: a=0.00575 (0.00336 - 0.00985), b=3.13 (2.98 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 3.0 ±0.07 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (tm=1).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).
