وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 7; الأشعة الظهرية الناعمة (المجموع) : 8 - 9; شوكة شرجية: 1; أشعه شرجية لينه: 8 - 9. Diagnosis: Eleotris valadei is distinguished by second, third and fourth suborbital free neuromast rows on cheek extending ventrally past horizontal row 'd' ('2.3.4' pattern), row 'os' connected with row 'oi' at ventro-posterior margin of operculum ('closed' pattern); 18 pectoral fin rays; 59-64 scales in lateral series and 27-30 scales in transverse forward series (Ref. 123271). Eleotris valadei differs from the other species of the Indian Ocean with a '2.3.4' pattern by several characters; it differs from E. soaresi in having more scales in lateral series, 59-64 vs. 50-56, more scales in transverse forward series, 27-30 vs. 22-24, in predorsal series, 45-50 vs. 39-43, and in zigzag series, 13-15 vs. 12-13; it differs from E. diamsoi in having 18 pectoral fin rays vs. 16, more scales in transverse forward series, 27-30 vs. 17-23, in predorsal series, 45-50 vs. 36-38, and a higher body depth at dorsal fin origin, 19-24 vs. 15-18 (Ref. 123271).
The species is supposed to be amphidromous (Ref. 123271). It is found in the lower part of the river, near the estuary; it lives in muddy to clear rivers with sandy to gravel bottom between 0 to 5 meters in altitude (Ref. 123271). It is carnivorous (Ref. 123271).
