Short summary
Prey noticing a predator may freeze (turn immobile) to avoid detection. Freezing is generally thought to precede predator–prey contact, but this may not hold for species of limited sensory abilities. The snail Agaronia detects its prey Pachyoliva, another snail, only when it is right before the predator, while Pachyoliva bumping into Agaronia's side avoids detection by freezing. This post-contact freezing reminds us to consider sensory capabilities when interpreting predator–prey interactions.
