ນິເວດວິທະຍາ
ສັດທະເລ ອາໄສຢູ່ໃກ້ໜ້າດິນໃຕ້ພື້ນທ້ອງນ້ຳ; ລະດັບຄວາມເລິກ 0 - 150 m (Ref. 2683), usually ? - 60 m (Ref. 3593). Tropical; 35°N - 17°S, 25°W - 14°E
Eastern Atlantic: Mauritania (Ref. 5377) to Angola, becoming scarce north of Cape Verde. Often confused with Pseudotolithus senegalensis.

Maturity: Lm 48.3 range ? - ? cm
Max length : 140 cm TL ຕົວຜູ້/ບໍ່ມີເພດ; (Ref. 40637); common length : 50.0 cm SL ຕົວຜູ້/ບໍ່ມີເພດ; (Ref. 4780); ນ້ຳໜັກສູງສຸດທີ່ເຄຍຈັດພີມມາ: 15.0 kg (Ref. 40637)
ຄີ (ໜາມ)ແຂງຢູ່ຫຼັງປາ (ທັງໝົດ) : 10; ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 28 - 32. Diagnosis: dorsal fin with 9 spines in the 1st part and 1 spine and 28-32 in the second; second anal spine about half the length of the 1st anal fin soft ray; pectoral fins short, about 19-21% SL; gill rakers short, about as long as gill filament at angle between lower and upper part of gill arch; maxilla extending beyond posterior eye border, eyes small, 7.2-8.4 times in HL, but this character is difficult to use for identification because of allometry (Ref. 81656).
Inhabits coastal waters from shoreline to about 150 m depth, over mud and sandy mud bottoms. Most abundant in waters less than 60 m at temperatures above 18°C. Juveniles and sub-adults enter estuaries and rivers. Feeds mainly on small fishes and crustaceans. Peak spawning season from late spring to early autumn in tropical West Africa (Ref. 4780).
