Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8-9; Anal spines: 1; Anal soft rays: 8 - 9. Diagnosis: Eleotris sahanaensis 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; 54-55 scales in lateral series and 29-30 scales in predorsal series (Ref. 123271). Within the pattern '2.4' group, E. sahanaensis differs from E. acanthopomus in having 15 pectoral fin rays vs. 16-17, 10 scales in zigzag series vs. 11-14, and 29-30 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. pellegrini by a smaller head length, 30-32% of standard length vs. 31-37%, and fewer scales in zigzag series, 10 vs. 10-12 (Ref. 123271).
