Synodontis schoutedeni, known as [1] the yellow marbled Synodontis,[2] is a species of upside-down catfish native to the Congo Basin of the Democratic Republic of the Congo and the Republic of the Congo.[1] It was first described by Belgian ichthyologist Lore Rose David in 1936, based upon a holotype discovered in Basongo, in what is now the Democratic Republic of the Congo.[1] The specific name "schoutedeni" is named after the Belgian zoologist Henri Schouteden.[3]
Description
[edit]The fish is cream-colored with a brownish-mauve marbled pattern on the head, body, and adipose fin.[3] Other fins are clear with dark spots.[3] The color patterns on the fish tend to become more pronounced in older individuals.[2]
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.[2] The first ray of the dorsal fin and the pectoral fins have a hardened first ray which is serrated.[2] The caudal fin is forked.[2] It has short, cone-shaped teeth in the upper jaw.[2] In the lower jaw, the teeth are s-shaped and movable.[2] The fish has one pair of long, dark-colored maxillary barbels, that reach as far as the base of the ventral fins, and two pairs of mandibular barbels that are often branched.[2][3] The pectoral fin spine is finely serrated on the outer edge, and heavily serrated on the inner edge.[3]
This species grows to a standard length of 12.7 centimetres (5.0 in) although specimens up to 17.1 centimetres (6.7 in) total length have been recorded in the wild.[1][2]
Habitat
[edit]In the wild, the species inhabits tropical waters with a temperature range of 22 to 26 °C (72 to 79 °F), a pH of 6.0 – 7.5, and dH range of 4-15.[1] It has been found in the central Congo River basin and in Pool Malebo.[4] It is harvested for human consumption.[4]
