小丑島位於綠島的西南側，於石朗保育區內。小丑島由多塊珊瑚礁所組成，上面長滿了海葵與一簇一簇的小丑魚，密集度高。小丑島四周是平緩乾淨的白砂，白砂在陽光的照映之下，折射出的光線，總使得攝影作品陽光充足、色彩透亮。
Nemo Island is a prime diving site in the Shilang area of Green Island, with an average depth of 12 meters. The reef is thriving with clownfish and surrounded by expansive, fine white sand. It is a highly recommended site for both scuba diving and freediving. If you approach the reef closely and listen carefully, you can actually hear the unique sounds made by the clownfish (Nemo). **Reminder: Please treat this delicate reef with care. Help us protect the marine ecosystem by avoiding any direct contact or disturbance to the coral.
