Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11 - 12; गुदा कांटा: 0; ऐनल सौफट रेज़: 9; जानवरों की रीड़ का जोड़: 33 - 34. Diagnosis: Enteromius yardiensis belongs to a phenotypic group characterised by small size and the last unbranched dorsal-fin ray thickened and serrated (Ref. 121538). It is readily distinguished from its Ethiopian congeners by three unique specialisations: the absence of the anterior barbel, the absence of the medial branch of the supraorbital cephalic canal and few, 1-3, commonly 2, scale rows between lateral line and anus (Ref. 121538). It further differs by posterior barbel usually shorter than half eye diameter; eye large, its diameter 24-34% of head length; snout short and pointed; lateral line complete and strongly curved; scales in the lateral series 32-35; few transversal scale rows between lateral line and pelvic-fin base, 1-3; scale rows between dorsal- and pelvic-fin origins 7-10; often four unbranched dorsal-fin rays; few branched pectoral-fin rays, commonly 12 or 13; 17-18 abdominal vertebrae; 10-12 predorsal abdominal vertebrae; and 6-9 vertebrae between first pterygiophores of dorsal and anal fins (Ref. 121538).
Found in shallow shoreline habitats of the main channel of Awash River, deep stretches of side channels, stagnant water bodies of the adjacent floodplain, and in the shoreline of the lakes (Ref. 121538). A preference for structured habitats with aquatic plants, woody debris, dense river bank vegetation and fine substrate, sand and finer fractions, was noted; a pronounced difference between wet and dry season is characteristic for the area Ref. 121538). Water is usually turbid and water temperature ranged from 26.1°C to 31.9°C (Ref. 121538). Gut contents contained unidentifiable fine organic detritus and remains of planktonic crustaceans but also nematodes, remains of terrestrial arthropods, diatoms, larger plant material, seeds, and wood debris, and some non-organic material (Ref. 121538).
