From: Comparative histology of muscle in free ranging cetaceans: shallow versus deep diving species
Mean fiber lesser diameter (LD) (μm) of Type II fibers in the shallow-diving group (D. delphis, S. coeruleoalba, S. frontalis) and deep-diving group (K. breviceps, M. europaeus, Z. cavirostris).
Left inset: Global mean fiber LD of Type II fibers were larger for the deep-diving group of animals. Asterisks denote significant differences across groups (P < 0.05, the Mann-Whitney U test).
