The Balabac Strait (Filipino : Kipot ng Balabak; Malay : Selat Balabak) [1] is one of the straits that connects the South China Sea with the Sulu Sea. It separates Balabac Island (Palawan province), Philippines, from Balambangan and the Banggi Islands north of Borneo that are a part of Malaysia's Sabah state. [2]
The strait is about 50 kilometres (31 mi) wide with a maximum depth of around 100 metres (330 ft). [3] It was therefore likely to have been below sea level before the last ice age and archaelogica; records indicate that there was an exchange of flora and fauna such as the Bornean tiger#Archaeological records between Borneo and the Palawans.

Palawan, officially the Province of Palawan, is an archipelagic province of the Philippines that is located in the region of Mimaropa. It is the largest province in the country in terms of total area of 14,649.73 km2 (5,656.29 sq mi). The capital and largest city is Puerto Princesa which is geographically grouped with but administered independently from the province. Palawan is known as the Philippines' Last Frontier and as the Philippines' Best Island.
The Sulu Sea is a body of water in the southwestern area of the Philippines, separated from the South China Sea in the northwest by Palawan and from the Celebes Sea in the southeast by the Sulu Archipelago. Borneo is found to the southwest and Visayas to the northeast.
Sundaland is a biogeographical region of Southeast Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower. It includes Bali, Borneo, Java, and Sumatra in Indonesia, and their surrounding small islands, as well as the Malay Peninsula on the Asian mainland.
The Philippine archipelago is one of the world's great reservoirs of biodiversity and endemism. The archipelago includes over 7000 islands, and a total land area of 300,780 km2.
Palawan is the largest island of the province of Palawan in the Philippines and fifth-largest by area and tenth-most populous island of the country, with a total population of 994,101 as of 2020 census. The northwest coast of the island is along the Palawan Passage in the eastern South China Sea, while the southeast coast forms part of the northern limit of the Sulu Sea. Much of the island remains traditional and is considered by some as under-developed. Abundant wildlife, jungle mountains, and some white sandy beaches attract many tourists, as well as international companies looking for development opportunities.
The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent 26,000 and 20,000 years ago. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing a major expansion of deserts, along with a large drop in sea levels.
Balabac, officially the Municipality of Balabac, is a 2nd class municipality in the province of Palawan, Philippines. According to the 2020 census, it has a population of 42,527 people.
The Invasion of Palawan, was fought by U.S. liberation forces against the Japanese from 28 February to 22 April 1945, in a series of actions officially designated as Operations Victor I and II, and part of the campaign for the liberation of the Philippines during World War II, was waged to initiate the recapture of the southern islands of the Philippine archipelago, end the Japanese occupation, and secure them from remaining Japanese forces.
The Mindoro Strait is one of the straits connecting the South China Sea with the Sulu Sea in the Philippines. It separates Mindoro Island from Busuanga Island. Located between the two islands is the Apo Reef, the largest coral reef system in the Philippines. The reef divides the strait into the Apo East Pass and the Apo West Pass.
Balabac Island is the southernmost island of Palawan province, and therefore the westernmost undisputed island in the Philippines, some 50 km (31 mi) north of Sabah, Malaysia, across the Balabac Strait. Administratively, the island forms the main part of the municipality of Balabac and is divided into 14 barangays :
Divisions are the primary subdivisions of Sabah and Sarawak, the states in East Malaysia. Each division is subdivided into districts — this is different in Peninsular Malaysia whereby districts are generally the primary subdivisions of a state. Each division is headed by a resident.
The Philippine deer, also known as the Philippine sambar or Philippine brown deer, is a vulnerable deer species endemic to the Philippines. It was first described from introduced populations in the Mariana Islands, hence the specific name.
The Calamian deer, also known as Calamian hog deer, is an endangered species of deer found only in the Calamian Islands of Palawan province in the Philippines. It is one of three species of deer native to the Philippines, the other being the Philippine sambar and the Visayan spotted deer.
The Palawan hornbill is a large forest bird endemic to the Philippines. It is one of the 11 endemic hornbills in the country. It is only found in Palawan and nearby islands of Balabac, Busuanga, Calauit, Culion and Coron. It is locally known as "talusi" in the language Cuyunon. It is threatened by habitat loss, hunting and trapping for the cage-bird trade.
Since H. Otley Beyer first proposed his wave migration theory, numerous scholars have approached the question of how, when and why humans first came to the Philippines. The current scientific consensus favors the "Out of Taiwan" model, which broadly match linguistic, genetic, archaeological, and cultural evidence.
The Palawan bearded pig is a pig species in the genus Sus endemic to the Philippines, where it occurs on the archipelago of islands formed by Balabac, Palawan, and the Calamian Islands. It is 1 to 1.6 m in length, about 1 m (3.3 ft) tall and weigh up to 150 kg (330 lb).
The Philippine long-tailed macaque is a subspecies of the crab-eating macaque, known in various Philippine languages as matching/matsing or the more general term unggoy ("monkey"). It is endemic to the Philippine forests and woodlands, but especially in the mangrove forests of western central Philippines— particularly in Palawan, the Visayas, and Mindanao. The names M. f. philippinensis and M. f. philippinenesis have also been used, but arise from orthographical error.
The island of Borneo is located on the Sunda Shelf, which is an extensive region in Southeast Asia of immense importance in terms of biodiversity, biogeography and phylogeography of fauna and flora that had attracted Alfred Russel Wallace and other biologists from all over the world.
Dewil Valley, located in the northernmost part of Palawan, an island province of the Philippines that is located in the Mimaropa region, is an archaeological site composed of thousands of artifacts and features. According to the University of the Philippines Archaeological Studies Program, or UP-ASP, the closest settlement can be found in New Ibajay, which is covered by the town capital of El Nido, which is located around 9 km (5.6 mi) south-east of Dewil Valley. Physically it measures around 7 km (4.3 mi) long, and 4 km (2.5 mi) wide. It is in this place which the Ille Cave, one of the main archaeological sites, can be found. It is actually a network of 3 cave mouths located at its base. It has been discovered that this site in particular has been used and occupied by humans over multiple time periods.
The Bornean tiger or Borneo tiger is possibly an extinct tiger population that lived on the island of Borneo in prehistoric times.
