Figure 2. Emergence of the OB phenotype via progressive loss of melanophores.

Figure 2

(A) Melanophore number and (B) contracted melanophore size were measured in the caudal fin of the same M. tarakiki individuals through juvenile development. Black and orange symbols indicate P and OB morph individuals, respectively (n = 8 each P and OB morph individuals; by morph t-test p values: *<0.05, **<0.01, ***<0.001). (C–E) Images of the same area of caudal fin in an M. tarakiki OB morph juvenile. On day 1 (C), a melanophore (arrowhead) is responsive to contraction by epinephrine. On day 2 (D) the melanophore responds abnormally with a partially contracted, blebbed appearance, and is cleared from the tissue by day 3 (E).
