Hydatina physis is a rarely seen nocturnal species that buries itself in sand during the day. It is found in tide pools and mixed habitats to depths of 1-2 m at moderately exposed sites. It feeds on polychaete worms, mussels and slugs and its egg mass is similar to that of Hydatina amplustre (more elongate). Its color can vary from very dark to a pale pinkish white.
