Myoglobin Concentration and Oxygen Stores in Different Functional Muscle Groups from Three Small Cetacean Species [PDF]
Animals, 2021 Compared with terrestrial mammals, marine mammals possess increased muscle myoglobin concentrations (Mb concentration, g Mb · 100g−1 muscle), enhancing their onboard oxygen (O2) stores and their aerobic dive limit. Although myoglobin is not homogeneously
