Long-term habituation to a danger stimulus in the crab Chasmagnathus granulatus
A shadow moving overhead acts as a danger stimulus and elicits an escape response in the crab Chasmagnathus granulatus, that habituates after 15 stimulus presentations at 3-min intervals. Here, the habituation was induced by 3 diverse shadow stimuli and the habituated response persisted after 24 hr...
