Prey animals must monitor and analyse the steady stream of sensory information for signs of predators and determine adequate escape strategies. This is problematic for small animals that often have simple nervous systems and limited sensory information. My research investigated the unique solutions fiddler crabs (Gelasimus dampieri) have evolved to overcome these problems and how they successfully deal with multiple, simultaneously approaching predators by using salience-based selective attention. Overall, my work highlights the importance of lifestyle and visual environment, in how small animals organise their behaviour to overcome their sensory limitations and escape from predators.
