Bigger, faster, but still outfoxed: How prey escape predators

Key Points:
- A new study from the University of Amsterdam challenges the traditional view that prey escape predators mainly due to superior maneuverability, revealing that reaction times play a crucial role in prey evasion.
- Researchers found that prey are generally not maneuverable enough to outturn faster predators, and paradoxically, aquatic environments—where prey are highly maneuverable—show the lowest predator capture success, about 10%.
- The key to prey escape lies in the delay predators experience in perceiving and reacting to evasive maneuvers, giving prey a critical head start even if only by fractions of a second.
- In aquatic settings, the high density of water allows prey to execute sharper turns, sometimes slipping behind predators before they can respond, highlighting the importance of environmental physics in predator-prey dynamics.
- Future research aims to determine if prey can time their evasive moves within the narrow 100-millisecond window predicted by the model, with ongoing studies filming real predator-prey interactions on coral reefs.
