Abstract in brief

The study investigates the physical constraints and conditions that enable aquatic and semi-aquatic animals to jump out of water by analyzing over 100 jumps across different species, and finds that the maximum jump height scales with body length and the Froude number, which measures the ratio of inertia to gravity.
Researchers conducted simplified experiments with axisymmetric bodies to observe the transition from partial to complete water exits, discovering that partial jumps scale with the Froude number as H/L ~ Fr, while complete jumps follow the same scaling pattern, highlighting different jumping regimes.
A bioinspired robotic model was created to mimic impulsive jumping, revealing that the entrainment of water (fluid carried along during exit) limits jumping height, and animals can reach higher jumps because they typically lack this entrained fluid, unlike the robots that carry more water and thus achieve lower jumps.
