Animals were sampled with a submersible and transferred into individual aquaria where their activity was monitored for 5 d by taking digital video snapshots every 30 s. An observer analysed the footage by counting the number of times an animal crossed two perpendicular lines drawn on a PC screen per 30 min interval. Resulting time series were represented over consecutive days and the waveform analysis was used to precisely assess the phase (i.e. the peak timing) and its limits (i.e. onset and offset) in relation to light ON and OFF. The majority (73%) of animals showed a marked nocturnal pattern of activity with number of movements close to zero during the photophase. Waveform analysis showed that the behavioural transition from activity to inactivity after light ON occurred within approximately 1 h. Considering the general lack of knowledge on the regulation of activity rhythms of crustaceans from subtidal areas, the present data provide a new insight on the role played by light in the regulation of animal activity rhythm in deep-water environments such as those of the cold seeps in the Gulf of Mexico. The experimental work of this study was supported by a Fondation Total Grant to E. Ramirez-Llodra and P. Tyler under the ChEss-Census of Marine Life Program. E. Ramirez-Llodra and M. Camps were supported by the ChEss-Census of Marine Life programme. J. Aguzzi is a Juan de la Cierva (MEC, Spain) posdoctoral fellow. G. Telesnicki was supported by the US NSF, the Minerals Management Service and The Penn State University.
