Ammocoetes: Max. size 17.2 cm TL. Body proportions, as percentage of TL (based on 12 specimens measuring 10.2-17.2 cm TL): prebranchial length, 5.9-8.3; branchial length, 9.6-11.8; trunk length, 51.7-55.0; tail length, 26.5-28.9. Trunk myomeres, 65-70. Extent of pigmentation (- = absence to trace; + = 1% to under 25%; ++ = 25% to under 75%; +++ = 75% or more): upper lip, - (100% of specimens); subocular, - (100%); upper prebranchial - (100%); lower prebranchial, - (100%); upper branchial, ++ (100%); caudal fin, ++ (100%); tongue precursor bulb, - (100%); along elastic ridge of tongue precursor, - (100%). Caudal fin shape, spade-like. Metamorphosing ammocoetes: lengths unrecorded (Ref. 89241). Transformation takes place in specimens as small as 11.7 and 12.2 TL (Ref. 1998). |
