Fig. 28 Lateral line development revealed by labeling with vital fluorescent dye FM1-43. Shown are multiple individuals in brightfield (left) and inverted epifluorescence (right; standard length [SL] at lower right). 3.5, Neuromasts of the posterior lateral line (arrowheads), with a cluster near the base of the tail; additional neuromasts are visible on the contralateral side. 5.8, Additional neuromasts have arisen between pre-existing neuromasts of the main lateral (L) line (arrowhead) whereas caudal neuromasts are found in an increasingly vertical line at the base of the caudal fin (arrow). 7.4, Neuromasts are apparent within the secondary lateral (L′) line (arrowhead) and at the base of the dorsal fin (arrow). 8.6, Additional neuromasts are seen in the secondary lateral (L′) line (arrowheads) and on the caudal fin itself (arrow).
