More definitive characteristics are the dorsal and anal fins, with the first dorsal fin possessing 11 spines while the second dorsal contains one spine and 17 or 18 soft rays posterior to the spines. The anal fin has two spines followed by 17 soft rays. Like all smelt-whitings, its body is covered in ctenoid scales, with a lateral line
