This special exhibition focuses on animals that are active in the middle of the night or in complete darkness. Around 20 species that thrive in dark environments are introduced under three categories: Nocturnal, Cave-dwelling, and Bioluminescent. The exhibition space is dimly lit, creating the atmosphere of exploring a nighttime forest or the depths of the ocean. Visitors can observe the behavior of nocturnal animals—usually asleep during the day—as well as creatures that glow in the dark. One highlight is a “peephole” where visitors can view the luminous splendid flashlight fish (Anomalops katoptron) using its light organ in darkness. Original merchandise featuring the animals in the exhibit will also be available for purchase.
