🐟 Physical Description

Dorsal spines (total): 6; Dorsal soft rays (total): 7 - 8; Anal spines: 1; Anal soft rays: 7 - 8; Vertebrae: 24 - 25. Diagnosis: It is distinguished from congeners by the absence of scales on the head, less the operculum, the presence of single and feeble leading spines in both the second dorsal and anal fins, a pelvic formula of I,5, the presence of an enlarged, bony operculum, and an overall more robust and heavier body, particularly in adults . Typhleotris pauliani is further distinguished from T. mararybe by the absence of pigment on the body and a longer prepelvic length (34.1-40.4% of standard length vs. 33.0-33.9% of standard length), and from T. madagascariensis by the absence of ctenoid scales on the flank and dorsum, except for a few weak ctenoid scales midflank in some individuals, more or less along the lateral midline . : elongated.
