Mugilidae (Mullets)
Etymology: Chelon: Greek, chelone = turtle (Ref. 45335); bandialensis: The epithet bandialensis indicates the species is from the Bandiala channel, the main arm of the Sine Saloum estuary in Senegal where the species was first collected (Ref. 89987).
Environment: milieu / climate zone / depth range / distribution range

Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 57.2 cm SL mannelijk / geslacht onbekend; (Ref. 28587)
Robust and rounded body. Head profile pointed, alike L. dumerili. HL about 23% SL. Adipose tissue forming a single small rim around the eye. Upper lip's thickness about 1/3 the eye diameter. Lower lip with a thin rim. Anterior edge of the upper jaw reaches the vertical limit of the anterior eye rim. Back silverish blue-grey, sides pale to silver-white with seven longitudinal grey lines. Anal and dorsal fins yellow. Caudal fin yellow with a black edge (Ref. 28587).
Maximal length observed during the redescription is 43.9 cm SL (Ref. 89987). It seems to be a rare and large species throughout its distribution; only specimens > 25 cm were observed so far (Ref. 89987). It status for the IUCN Red List of Threatened Species is recommended as "Data Deficient" (Ref. 89987).
