Oreochromis karomo

ΑγγλικάDiagnosis: tasselled species (Ref. 2). Adults with all teeth of the jaws tricuspid (Ref. 2, 55074), with long, slender shafts and curved crowns, arranged in broad bands (Ref. 2). Jaws much enlarged, projecting forwards to form a long snout (Ref. 2), with the tooth bands meeting in the horizontal plane (Ref. 2, 4967). Maxilla with a flange resting on the premaxilla at the curve between its two arms (Ref. 2). Description: mouth and lips large; maxillary not reaching anterior border of eye (Ref. 53528). Premaxillary pedicels (ascending processes) reinforced posteriorly and, asymmetrically, on their lateral faces; jaw teeth movable (Ref. 2). Broad bands of teeth visible when the mouth is closed (Ref. 54836). Blade of lower pharyngeal jaw nearly twice as long as the median length of the toothed area; pharyngeal teeth slender, crowded and movable (Ref. 2). Scales on cheek in 2 or 3 rows (Ref. 2, 53528, 55078). 4-5 scales between bases of pectoral and pelvic fins (Ref. 2). Upper lateral line with 20-21 scales, lower with 11-12 scales; 14 scales between upper lateral line and medioventral line; abdominal and especially thoracic scales relatively small (Ref. 53528, 55078). Lateral line extending for 2 scales on caudal fin base (Ref. 55078). Dorsal fin almost reaching middle of caudal fin in adults and the caudal fin base in juveniles; anal fin reaching as far as dorsal fin; pectoral fin always reaching beyond vent (Ref. 55074). Pelvic fins extending to vent or genital papilla (Ref. 2), but never as far as the pectoral fins (Ref. 55074). Caudal fin finely scaled, except at the border (Ref. 53528, 55078). Genital papilla enlarged, bifid and dendritic in mature fishes of both sexes (Ref. 2), in breeding males up to 10-15cm, with semitransparent filaments and blobs of bright orange tissue (Ref. 2, 55077), but in mature females only about 5mm long (Ref. 2). Coloration: Non-breeding fishes: ground color olive, darker on the upper part of the body by reason of black center to each
