At night, an individual of the opisthobranch Hydatina physis crawled out of the sand on the bottom of an aquarium. As I turned on the light to watch it closely, it started digging back into the sand. It is digging headfirst into the sand in the same manner as we crawl under a ¡Æfuton¡Ç. The entire body was under the sand in 5 minutes. (translated by Asoh)
