The sharptooth lemon shark can be seen year-round near the Dongsha Islands. This is because the diverse marine environment of seaweed beds, coral reefs, and lagoons of Dongsha Atoll National Park provides an ideal place for lemon sharks to nurture their young, and for other large cartilaginous fish to feed. The Marine National Park Headquarters has compiled recent years' lemon shark survey results into a booklet. This helps the public see the ecology of these sharks, so inaccessible in everyday life, through soft brush-stroke illustrations.

708 species of fish have been recorded from surveys in the Dongsha reefs. Long-term investigations by National Cheng Kung University and Aletheia University research teams have found that lemon sharks birth their pups every spring in the Dongsha Island Lagoon. Most recorded sharks are young and under the age of three, leading to preliminary speculations that lemon sharks tend to swim to deeper waters after reaching the age of three.Publications
