| Ammocoetes: Max. size approximately 220 mm TL. Wet weight of individuals 7-180 mm TL, 0.1-6.9 g. Body proportions, as percentage of TL (based on 400 specimens measuring 7-180 mm TL, average of 76 mm; average values given in parentheses due to the wide ranges for body proportions of available specimens; also, data are taken from Kucheryavyi et al. (2007) and may include some larval L. kessleri): prebranchial length, 4.9-22.1 (8.4); branchial length, 7.0-43.0 (15.4); trunk length, 17.5-61.1 (46.8); tail length, 18.9-79.6 (31.7). Metamorphosing ammocoetes: approximately 140-184 mm TL (The latter number represents an average length). |
