Ammocoetes: Max. size known 148 mm TL (possibly >166 mm TL, the longest recorded length of adults). Body proportions, as percentage of TL (based on nine specimens measuring 90-142 mm TL): prebranchial length, 7.0-7.9; branchial length, 12.5-13.7; trunk length, 50.4-54.0; tail length, 25.1-28.7. Trunk myomeres, 56-60. Extent of pigmentation (- = absence to trace; + = 1% to under 25%; ++ = 25% to under 75%; +++ = 75% or more): upper lip, + (11% of specimens), ++ (22%), +++ (67%); cheek, ++ (33%), +++ (67%); subocular, - (22%), + (11%), ++ (33%), +++ (33%); upper prebranchial, +++ (100%); lower prebranchial, + (33%), ++ (67%); upper branchial, ++ (33%), +++ (67%); lower branchial, - (100%); ventral branchial, - (89%), + (11%); caudal fin, + (100%); tongue precursor bulb, -; along elastic ridge of tongue precursor, +. Lateral line neuromasts unpigmented. Tongue precursor bulb shape triangular. Caudal fin shape, rounded or spade-like. Body coloration (live and freshly preserved) is gray on the dorsal aspect and lighter on the ventral aspect and without mottling. Metamorphosing ammocoetes: size unrecorded (Ref. 89241).
