Synodontis albolineatus, known as the mustard catfish,[2] or the mustard squeaker,[3] is a species of upside-down catfish native to Gabon and Cameroon, where it occurs in the Ntem and Ivindo rivers.[4] It was first described by French zoologist Jacques Pellegrin in 1924, based upon a holotype discovered in the Djoua River at Madjingo, Gabon.[5] The holotype specimen resides in the Musee National d' Histoire Naturelle de Paris.[3] The specific name "albolineatus" is a composite from the Latin word albus for "white" and the Latin word linea for "line", which refers to the white midlateral stripe of the species.
Description
[edit]The body of the fish is a dark brown to black with turquoise-brown marbled or spotted markings; spots are smaller on the head.[3][4] A thick, white lateral line appears in adults that horizontally along the length of the fish.[2] The fins are clear with brown spots.[3] The dorsal fin is composed of one prominent hard spine and seven soft rays.[4]
Like other members of the genus, this fish has a humeral process, which is a bony spike that is attached to a hardened head cap on the fish and can be seen extending beyond the gill opening.[5] The first ray of the dorsal fin and the pectoral fins have a hardened first ray which is serrated.[5] The caudal fin is forked with two equal lobes.[4] It has short, cone-shaped teeth in the upper jaw.[5] In the lower jaw, the teeth are s-shaped and movable.[5] The fish has one pair of maxillary barbels, and two pairs of mandibular barbels that are often branched.[2][5]
This species grows to a length of 10 centimetres (3.9 in) SL although specimens up to 17.2 centimetres (6.8 in) TL have been recorded in the wild.[4][5]
Habitat
[edit]In the wild, the species has been found in only four locations on the Ntem and Ivindo rivers.[1]
