Figure 5. Percentage of red and intermediate fibers in three muscles in Sicyopterus stimpsoni.

(A) Comparison of red and intermediate fiber contribution across muscle types, independent of stream segment; (B) % red and intermediate muscle fibers in adductor pectoralis, a muscle not involved in climbing; (C) % red and intermediate muscle fibers in the abductor pelvicus complex muscle; (D) % red and intermediate muscle fibers in the adductor pelvicus complex muscle. Sample size indicated in each column. Letters above columns indicate statistically significant differences between columns (p<0.05; Kruskal-Wallis with Dunn’s post-hoc test).
