توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 7; شعاع نرم باله پشتي (کل) : 8 - 9; خارهاي باله مخرجي: 1; شعاع نرم باله مخرجي: 8 - 9. Diagnosis: Eleotris pellegrini is distinguished by second and fourth suborbital free neuromast rows on cheek extending ventrally past horizontal row 'd' ('2,4' pattern), row 'os' not connected with row 'oi' at ventro-posterior margin of operculum ('open' pattern); 15 pectoral fin rays; no teeth on vomer; scales in zigzag series 10-12, and 18-24 in transverse forward series (Ref. 123271). Within the pattern '2.4' group, Eleotris pellegrini differs from E. acanthopoma in having 15 pectoral fin rays vs. 16-17 and 28-34 scales in predorsal series vs. 30-42; it differs from E. vomerodentata by the absence of teeth in the vomer vs. presence; it differs from E. sahanaensis by a greater head length, 31-37% of standard length vs. 30-32%, and more scales in zigzag series, 10-12 vs. 10 (Ref. 123271).
This species is supposed to be mainly amphidromous (Ref. 123271). Maximum size up to 64 mm standard length (Ref. 123271). Epibenthic in fresh and brackish waters (Ref. 6802); it lives in the lower part of rivers, in muddy to clear rivers with sandy to gravel bottom between 5 to 10 m in altitude (Ref. 123271). It is carnivorous (Ref. 123271).
