South America is a vast continent endowed with extraordinary biodiversity that offers
abundant opportunities for neuroethological research. Although neuroethology is still …

Predator avoidance and prey capture are among the most vital of animal behaviors. They
require fast reactions controlled by comparatively straightforward neural circuits often …

Similar to most visual animals, the crab Neohelice granulata relies predominantly on visual
information to escape from predators, to track prey and for selecting mates. It, therefore …

Decision-making processes in the context of prey–predator interactions are studied from the
side of the prey or the predator. Thus, prey capture and escape behaviours are researched …

Predation risk imposes strong selection pressures on visual systems to quickly and
accurately identify the position and movement of potential predators. 1, 2 Many invertebrates …

Animals use binocular information to guide many behaviors. In highly visual arthropods,
complex binocular computations involved in processing panoramic optic flow generated …

In order to cope with the challenges of living in dynamic environments, animals rapidly
adjust their behaviors in coordination with different physiological responses. Here, we …

The crab Neohelice granulata inhabits mudflats where it is preyed upon by gulls and,
conversely, preys on smaller crabs. Therefore, on seeing moving stimuli, this crab can …

Selective attention, the ability to focus on a specific stimulus and suppress distractions, plays
a fundamental role for animals in many contexts, such as mating, feeding, and predation …

Looming-sensitive neurons (LSNs) are motion-sensitive neurons tuned for detecting
imminent collision. Their main characteristic is the selectivity to looming (a 2D representation …
