Amissidens hainesi, the ridged catfish, is the only species of catfish (order Siluriformes) in the genus Amissidens of the family Ariidae.[1] This species occurs in marine and brackish waters on the southern coast of New Guinea and Northern Australia, between Darwin and southern Gulf of Carpentaria.[1][2]

The eyes are large. The lips are fleshy and thin and the mouth is small and almost quadrangular.[2] The barbels are thin and short; the maxillary barbels only reach just beyond eye, and the bases of the chin barbels are close together. The fin spines are thin, long, slender. The adipose fin has a short base and is over the posterior two-thirds of the anal fin. The ventral fin pad of sexually mature females is scalloped and tapered. It is dark grey above and iridescent purple.[3] This fish reaches about 30.2 centimetres (11.9 in) SL.[2]
