Scientific Name
Sillago analis

Common Name
Golden-lined sillago

Biology
Dorsal spines (total): 12; Dorsal soft rays (total): 16-18; Anal spines: 2; Anal soft rays: 14 - 17; Vertebrae: 33 - 34. The shape of the swim bladder is not distinguishable from that of S. ciliata. The anterior part of the swim bladder has rudimentary tubules projecting anteriorly and a lateral series, that diminishes in size and becoming sawtooth-like, projecting posteriorly. Body is light silvery, slightly darker to dusky dorsally. A dull golden silver to golden yellow stripe is below the lateral line. The pelvic and anal fins are pale yellow to bright yellow; the pectoral fin has a darker dusting of fine black-brown spots.
