In this study, we developed a new method to observe the gut content of juvenile sea cucumber. Apostichopus japonicus. We applied Bleaching Method to observe diatoms taken in by the juvenile sea cucumber and compared with Dissecting Method. By Bleaching Method, we could handle large number of sea cucumbers without any loss or destruction of diatom frustule. From the observation of juvenile sea cucumbers (size range: 288 - 791 um body length) , reared with natural benthic diatoms cultivated in Shikabe, southeastern Hokkaido, it revealed that juvenile sea cucumbers were able to take in 8 um to 128 um length benthic diatoms.
