Größe / Gewicht / Alter
Geschlechtsreife: Lm ? range ? - ? cm
Max length : 8.5 cm TL Männchen/unbestimmt; (Ref. 9760)
Rückenflossenstacheln (insgesamt) : 5 - 7; Rückenflossenweichstrahlen (insgesamt) : 6 - 8; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 7 - 10. Gill rakers short, with spinules, 1-13 on first lower gill arch. Anus very close to origin of fin. Second dorsal fin with I spine, 6-8 rays; anal fin with I spine and 7-10 rays. Midlateral scales 29-33.
Body shape (shape guide): elongated; Cross section: oval.
Essentially an estuarine species and coastal species, co-occurring with C. pauciradiatus, C. mugiloides and Atherinomorus endrachtensis. Biology not known except that it can withstand very high salinities. Probably taken as food by larger commercial species. (Ref. 9760).
