Ammocoetes: approximated max. size at least 228 mm TL (based on adult size), largest recorded at 153 mm TL; body proportions, as percentage of TL (based on 25 specimens 78-153 mm TL): 6.1-9.0 prebranchial length, 10.1-13.7 branchial length, 47.0-52.4 trunk length and 30.5-35.2 tail length; trunk myomeres, 56-65. Pigmentation in ammocoetes (- = absence to trace; + = 1% to under 25%; ++ = 25% to under 75%; +++ = 75% or more): upper lip, ++ (20% of specimens) or +++ (80%); subocular, ++ (8%) or +++ (92%); lower prebranchial, ++ (12%) or +++ (88%); upper branchial, ++ (88%) or +++ (12%); lower branchial, none; caudal fin, ++ (32%) or +++ (68%); tongue precursor bulb, + or ++; along elastic ridge of tongue precursor, +++; lateral line neuromasts, unpigmented; caudal fin shape, spade-like.
