Ammocoetes: Max. size 189 mm TL. Body proportions, as percentage of TL (based on 237 specimens measuring 33-189 mm TL): prebranchial length, 6.6-13.6; branchial length, 10.9-16.2; trunk length, 46.8-55.4; tail length, 21.2-31.7; cloacal slit length, 0.7-1.8; prenostril length, 1.9-4.6. Trunk myomeres, 53-63. Extent of pigmentation (- = absence to trace; + = 1% to under 25%; ++ = 25% to under 75%; +++ = 75% or more): upper lip, + (12% of specimens), ++ (78%) or +++ (9%); between upper lip and cheek, -(4%), + (21%), ++ (40%) or +++ (36%); cheek, + (4%), ++ (24%) or +++ (72%); subocular, - (34%), + (27%), ++ (10%) or +++ (29%); upper prebranchial, - (63%), + (33%), ++ (4%) or +++ (1%); lower prebranchial, - (83%), + (16%) or ++ (2%); upper branchial, + (3%), ++ (94%) or +++ (2%); lower branchial, - (48%), + (51%) or ++ (1%); ventral branchial, - (28%) or + (72%); lower lip, + (8%), ++ (45%) or +++ (47%); caudal fin, + (1%), ++ (86%) or +++ (13%); predorsal, - (4%), + (16%), ++ (32%) or +++ (48%); tongue precursor bulb, - (54%) or + (46%); along elastic ridge of tongue precursor, - (36%), + and ++ (18% each) or +++ (27%).
