During a single lunge, a fin whale can decelerate rapidly due to the immense drag created by mouth expansion.
During lunge feeding, fin whales accelerate toward prey before opening their mouths to engulf water. Fluid dynamics modeling published in Journal of Experimental Biology quantified drag forces that spike dramatically during mouth expansion. The sudden increase in cross-sectional area creates resistance that rapidly slows forward motion. Muscular effort must overcome this drag to capture prey efficiently. Tag data confirm brief but intense energy expenditure. Feeding efficiency depends on optimizing acceleration and engulfment timing. Hydrodynamic trade-offs define foraging strategy. Giants operate within strict physical limits. Motion balances cost and reward.

Hydrodynamic modeling refines energetic estimates used in ecosystem simulations. Institutions incorporate drag coefficients into metabolic calculations. Government agencies rely on such data to assess habitat carrying capacity. Feeding physics intersects with prey management policy. Quantitative biomechanics enhances predictive accuracy. Science integrates movement and conservation planning. Physical laws shape biological potential.
For observers, imagining water resistance halting a 70-ton animal mid-lunge emphasizes scale. Momentum yields to fluid drag. Feeding becomes mechanical event. Precision mitigates inefficiency. The whale’s mass does not exempt it from physics. Ocean density governs movement. Giants adapt to constraint.
