Leptocephalus larva; elongate with filiform tail; distinguished from A. infans by position of liver (myomere 40) and last vertical blood vessel (80-100th myomere) (Ref. 265). Nephros at about myomere 85 (81-88); maximum body length at about 260 mm (Ref. 32364). Pigmentation: dorsally on notochord; four clusters (1-5 dots each) below lateral midline at myomeres 18-23, 35-44, 69-81, and 103-123; dorsally on gut; dorsal and analfin bases; larvae >120.8 mm have ventral patch posterior to heart (Ref. 32364). Sequence of fin development: dorsal and anal (late) and caudal, pectoral. |
