Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm 8.0  range ? - ? cm
Max length : 33.0 cm TL maschio/sesso non determinato; (Ref. 7251); common length : 20.0 cm TL maschio/sesso non determinato; (Ref. 9626); peso massimo pubblicato: 550.00 g (Ref. 9626); Età massima riportata: 2.00 anni (Ref. 3422)
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 3; Raggi anali molli: 10 - 11. Large intestine makes up 90% of digestive tract and is twice the standard length, on the average; the stomach with 7 digestive caeca attached near the pyloric region. Pelvic fin coloration totally or partially dark in males; orange colored in females. Large dark spot (about same size as eye) below lateral line just behind gill opening (Ref. 26938).
Body shape (shape guide): short and / or deep.
Commonly found over mud bottoms in mangrove sloughs and on vegetated sand bottoms, sometimes in brackish water and occasionally also in coral reef areas near mangroves. Feeds on benthic invertebrates (small bivalves, crustaceans), as well as on plant material.
