Answer: Great Chagos Bank, Indian Ocean
Notes: Scientists have recorded the sliteye shark for the first time in the Great Chagos Bank, the world’s largest coral atoll. The shark is named for its narrow slit-like eyes and was filmed in deep seagrass habitats on the southern rim of the Bank. Two sharks were recorded 11 km apart at depths of 23–29 metres using Baited Remote Underwater Video systems. The species usually lives in deep waters but also adapts to shallow clear seas. The study shows that sliteye sharks also depend on these meadows, highlighting their biodiversity value. Sliteye sharks are listed as near-threatened and may decline by 30% in 15 years due to fishing pressure.
