Water entry and exit in nature: review. [PDF]

open access: yesInterface Focus
Aquatic animals that live in water often leap out to catch prey in the air, while terrestrial and aerial animals dive into water to hunt aquatic animals. Some animals locomote on the water surface or lap water by repeated slamming and water-exiting motions.
