Issue
Genetic data indicate that Chelon dumerilii is a complex of two species, one from Northwest and West central African coasts (= C. dumerilii), one in southeastern African coasts (Refs. 114224, 123262).
Environment: milieu / climate zone / depth range / distribution range
生态学
海洋; 淡水; 半咸淡水 居于水底的; 降海洄游 (Ref. 51243). 20°C - 25°C (Ref. 13614); 21°N - 36°S, 20°W - 38°E
Eastern Atlantic: Mauritania to South Africa (Ref. 3573, 57400). Western Indian Ocean: Delagoa Bay, Mozambique to Mossel Bay, South Africa (Ref. 81659).
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 17.0 range ? - ? cm
Max length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 4393); common length : 18.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 7399)
背棘 (总数) : 5; 背的软条 (总数) : 8 - 9; 臀棘: 3; 臀鳍软条: 8 - 9. Diagnosis: 8-9 anal soft rays; anal fin and lower lobe of caudal fin whitish or greyish (Ref. 57400). Body with ctenoid scales except for anterior predorsal scales which are cycloid and extend to anterior nostril or slightly beyond (Ref. 81659). Scales numerous (Ref. 57400), not large, 33-41 in a longitudinal series (excluding scales on caudal fin base), 11-14 scale rows between pelvic and first dorsal fin (Ref. 81659). 5-8 mucous canals on scales in front of 1st dorsal fin (only 1, less often 2 or 3, in other Liza species (Ref. 57400). Posterior end of maxilla sigmoid, curved down over premaxilla; serrate, anteroventral edge of lachrymal distinctly concave; pharyngobranchial organ with 1-2 valves, anteroventral valve a moderate size, semi-lunate flap, posterior valve usually vestigial, as a small nodule or, at most, a low papillate fold, and may be absent (Ref. 81659).
Inhabit shallow coastal waters (Ref. 27121), including estuaries (Ref. 2683, 57400, 81659), lagoons (Ref. 57400), tidal rivers (Ref. 3573), freshwater and supersaline environments (Ref. 81659). Feed on plankton and detritus (Ref. 28587). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Shows a remarkable adaptation to hyperhaline environments (up to 97‰ in the Sine Saloum in Senegal)(Ref. 57400). Specimens from tropical East Atlantic reaching maximum of 280 mm SL and common to 180 mm SL (Ref. 81659).
