Currently, the number of the research by Japanese zoos and aquariums is quite limited. Although all institutions are suffering from a shortage of the research funds and workers, the biggest issue is the luck of know-how. This article introduces the following 5 steps about the research method which the author has actually conducted in the zoo: ①Setting up the research purpose, ②Collecting the data, ③Hypothesis verification approach, ④Considering the meaning of the result and ⑤Publishing the result as an oral presentation or a manuscript. The author expects that this information contributes the invigoration of the research by zoos and aquariums in the future. Extending knowledge and information obtained by zoos and aquariums to the public is one of the important roles. In addition, the research activity might be useful to enhance the specialty of the staff. The author hopes that many staffs start the research by themselves.
