The main means of livelihood of the people is farming and fishing. The municipality's marine environment is home to various species of marine wildlife and plants, the most important of which is the giant tamilok, the largest shipworm species in the world. The species can only be found within the area, and no where else in the world, making Kalamansig an important biodiversity area. Formerly hunted by the locals, the giant tamiloks are now strictly protected by the municipality, specifically the former hunters of the species, after research confirmed the high importance of the species in the area's biodiversity.[4]

The existing seat of government of Kalamansig was formerly the municipality of Lebak. The first attempt to separate was on Lebak (presently Kalamansig) was under the municipal district of Kiamba while Salaman(now Lebak) use under the district of Dinaig on August 18, 1947 under Executive order 82.[6] and it was again reunited under one independent municipality of Lebak on December 31, 1948. The seat of government was transferred to Salaman on April 12, 1951.

Ten years later, the Municipality of Kalamansig formally created by the virtue of Executive Order 459 dated December 29, 1961 signed by Carlos P. Garcia,[7] creating the municipality of Kalamansig from certain barangays of Lebak and Palimbang.

There are 20 barangay and sitio carve out from Lebak are Lun, Pitas, Dansalan, Pedtegenan, Madu, Port Lebak, Lenek, Sta. Clara, Sebayor, Nalilidan, Bosawon, Calubcub, Camp III, Poral, Limulan, Simsiman, Cadiz and Tipudos. The 8 barangays and sitios were taken from Palimbang are Sangay, Mat, Danawan, Paril, Babancao, Basiawan, Narra and North Kulaman.

The municipality of kalamansig was transferred from Cotabato Province to Province of Sultan Kudarat on November 22, l973 by presidential decree 341 by President Ferdinand E. Marcos.[8] Kalamansig lies the few miles from the epicenter of the devastating 1976 Moro Gulf earthquake.

In 2004, gigantic shipworms were discovered by the locals within the municipal waters. In 2017, the shipworms were formally researched on by local and international scientists. The research confirmed that the giant Kalamansig tamilok is kuphus polythalamia and is the largest species of its kind in the world. Due to the research, Kamalansig became the first and only known permanent natural habitat of the endangered species.[9][10]


Like most municipalities in the Philippines, Kalamansig traces its name from various legendary origins. A popular folklore among the Manobos, a tribe of people who were among the earliest inhabitants of the place, explained that the name originated from a phrase “Kulaman-su-wayeg”, which literally translates as “Kulaman in the water”. Kulaman is said to be a famous Sultan of the Valley during the seventeenth century. According to the legend, a long famine came to the place and the Sultan, who was a loving father and provider to his family, ventured alone and gathered cassava, a staple food of the Manobos, for their consumption. Before returning home, the Sultan decided to wash the root crop in a river, but a sudden and strong river current arrived and swept the aging Sultan from his feet, carrying him downstream and was drowned in the process. His body was later found and recovered downriver, coining the word “Kulaman-sa-ig” (Kulaman in the water).

The name evolved into “Kalamansig” which later become the official name. In honor of this Manobo tribal leader, the river where he was found was named after him and later, the entire upper valley was called “Kulaman”. This barangay is now part of the Municipality of Sen. Ninoy Aquino.
