Growth of stitches can occur through addition of a dorsal bud neuromast (A and A′) or a ventral one (B and B′) or both (C and C′). Long periods can go by without any increase in stitch size (1 mo between D and D′). Conversely, a bud neuromast may be added in 2 wk, without anymore budding over the next 2 mo (E–E′ ′). Bud neuromasts may also be formed by other bud neuromasts within a stitch (F). (A and A′) Same fish at 3 mpf, 25 mm and at 4 mpf, 28 mm. (B–D) Same fish at 3 mpf, 25 mm and at 4 mpf, 29 mm. (B and B′) Stitch on somite 17. (C and C′) Stitch on somite 18. (D and D′) Stitch on somite 20. (E) Three-months post-fertilization, 26-mm fish. (E′) Ten days later, same size. (E′ ′) One month later, 28 mm. (F) Five-months post-fertilization fish, 3.1 cm. Arrows point to new bud neuromasts. (A–E) Maximal projections from confocal stacks. (F) Fluorescence image. |
