How do tigers move prey twice their mass? They use a specialized biomechanical strategy called straddle walking. Instead of dragging a kill laterally, the tiger positions the carcass directly under its belly. This aligns the prey's mass with the predator’s center of gravity, distributing the heavy load to core muscles. This behavior minimizes ground friction, conserves vital metabolic energy, and accelerates transit to a secluded feeding site away from scavengers.VC: mayank_bandhavgarh_#Wildlife
