The Sunda Shelf is a submerged continental shelf located in Southeast Asia, primarily surrounding the islands of Borneo, Sumatra, and Java. It is part of the larger Sundaland region, which was once connected to the Asian mainland during periods of lower sea levels. This shelf is rich in biodiversity and is home to various marine ecosystems. The Sunda Shelf is significant for its geological features and natural resources, including oil and gas reserves. It also plays a crucial role in the region's fisheries, supporting the livelihoods of many coastal communities. The shelf's unique environment contributes to the overall ecological health of the Coral Triangle.
