Ammocoetes: Max. size, 135 mm TL, but presumably can attain greater lengths as adults have been recorded to 178 mm TL. Body proportions, as percentage of TL (based on 44 specimens measuring 100-130 mm TL): prebranchial length, 5.2 (estimated mean); branchial length, 10.8-15.4; trunk length, 50.3-56.2; tail length, 26.5-30.8. Trunk myomeres, 51-60. Body coloration unrecorded. Extent of pigmentation (- = absence to trace; + = 1% to under 25%; ++ = 25% to under 75%; +++ = 75% or more): upper lip, +; cheek, +++; subocular, -; lower prebranchial, ++; upper branchial, ++; lower branchial, -; caudal fin, +; tongue precursor bulb, ++; along elastic ridge of tongue precursor, ++. Lateral line neuromast pigmentation unrecorded. Caudal fin shape, rounded. Metamorphosing ammocoetes: 86-114 mm TL. |
