Etymology: Ctenochromis: Greek, kteis, ktenos = comb + Greek, chromis = a fish, perhaps a perch (Ref. 45335); scatebra: The species is named from the Latin noun 'scatebra', meaning 'spring' or ' a gush of water from the ground', referring to the type locality which is a spring in northern Tanzania (Ref. 127080).

Краткое описание
морфология | морфометрия
колючие лучи спинного плавника (общее число): 14 - 15; членистые (мягкие) лучи спинного плавника (общее число): 8-9; колючие лучи анального плавника 3; членистые (мягкие) лучи анального плавника: 7 - 8. Diagnosis: Ctenochromis scatebra is recognised as a member of Ctenochromis because it possesses the diagnostic feature of a sharp break from small anterior scales to large posterior scales between the pectoral and pelvic fins, and it possesses scaleless areas on either side of the chest (Ref. 127080). In C. scatebra squamation is absent from the ventral part of the cheek, which is characteristic of the genus Ctenochromis; mature adult male of C. scatebra possess at least one clear non-ocellate egg spot on the anal fin (Ref. 127080). Ctenochromis scatebra can be distinguished from C. pectoralis based on two aspects of trophic morphology: it has front teeth in the outer row on both jaws that are primarily unicuspid, widened, shovel shaped, and often slanted, while side teeth in the outer row are unequally bicuspid and pointed; by contrast all front and side teeth in the outer row of C. pectoralis are all unequally bicuspid and pointed; Ctenochromis scatebra has a retrognathous jaw, while C. pectoralis has a marginally prognathous jaw (Ref. 127080).
This species has been observed feeding upon epilithic and epiphytic algae in Chemka Springs, as well as sifting soft sediment, and pecking on skin of swimmers; it is therefore most likely an omnivorous generalist (Ref. 127080).
