Deep-ocean animals remain poorly understood compared to their shallow-water relatives, mainly because of the great cost and difficulty involved in obtaining reliable ecological data. This is a serious issue as exploitation of deep-water resources progresses without sufficient data being available to assess its risks and impacts. First described almost 40 years ago, the use of baited cameras was pioneered by deep-sea biologists and is now a widely used technique for the assessing patterns of animal behaviour, abundance and biodiversity. The technique provides a non-destructive and cost-effective means of collecting data, where other techniques such as trawling are difficult or impractical. This review will first describe the evolution of baited camera techniques in deep-sea research from the early deployments, through recent programs to investigate trends in animal distribution with depth, latitude, and ocean basin. In the second section the techniques used for imaging, baiting, and analysis are synthesized, with special consideration for the modeling techniques used in assessing animal abundance and biomass.
