← Nature & AnimalsWhich mechanism enhances hunting success when orcas pursue faster dolphins?
A)Specialized muscle fiber recruitment✓
B)Increased red blood cell volume
C)Enhanced underwater visual acuity
D)Heightened sensory cortex activation
💡 Explanation
Specialized muscle fiber recruitment provides the necessary bursts of speed, because anaerobic glycolysis fuels short, intense sprints; therefore orcas can overtake dolphins, rather than relying solely on aerobic endurance for prolonged chases.
