Introduction Neohelice granulata crabs live in mudflats where they prey upon smaller crabs.
Predatory behavior can be elicited in the laboratory by a dummy moving at ground level in …

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 …

ABSTRACT Fiddler crabs (Uca pugilator Bosc; Crustacea, Decapoda) feed and court in
open, flat spaces. Their visual system has several putative adaptations to their flat habitat …

The horseshoe crab, Limulus polyphemus, has long been an admirable model for vision
research. More than 70 years of research on the physiological properties of the Limulus …

Escape decisions to predators are influenced by aspects such as prey's visual perspective,
in which visual cues are essential to detect and react to predators. Crabs use the visual …

Male fiddler crabs, Uca pugilator (Crustacea: Decapoda), respond to conspecifics by claw
waving, and to predators by freezing or escape. In field experiments it was found that this …

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

The efficiency of predator avoidance strategies depends on the availability and accuracy of
sensory information. Although vision can in principle provide instant information on a …

Crabs have proven to be a valuable model system for the study of the neural control of the
'escape response'(1). Their main advantages are that they allow study of their escape …

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 …
