抄録: To fulfill information gaps of underwater animal behavior, variety of animal-borne observation systems have been developed in last several decades, which revealed diving behavior, foraging behavior of many endotherms, particularly seals and penguins by providing information on many dive parameters, such as dive depth, dive angles, dive profiles, swim speed, body motion, body postures, ambient temperatures, 3D dive paths and so on. Above advanced animal-borne systems supported us to obtain reliable data both in quality and quantity regarding diving behavior, particularly foraging behavior, which have been hidden underwater for long period. Challenges to reveal foraging behavior of diving animals developed new hypotheses regarding foraging strategies of diving animals. Accordingly it was expected to develop a new tool to examine the hypotheses. A tool to obtain visual information on prey items, distribution and prey capturing events was strongly expected to be developed. Corresponding to above expectation several types of image data loggers were developed in recent years and have been used for variety of research purposes. Here I review the current system of image data loggers and concurrently role of image data loggers in studies of diving animals.
