This is the fourth part of the list of 10 tribes in Davao.
The Clatas occupy a very small territory stretching from Catalunan to Calinan within Davao City. Their traditional population centers included Biao, Tagakpan, Dulian, Sirib, Gumalang, and Tamugan. They are also known as Giangan, with variants like Guangan, Gulangan, or Jangan, that means forest dweller.
The boundary between Tagabawa and Clata was fixed at Lipadas River. Talomo River (ikawayanlinan) served as the boundary among the Tagabawas, Clatas and Obos. Davao River became the boundary between Bagobos and Clatas in the northeast part of Davao. Matina was apparently originally Clatas but they were pushed back by the Bagobos who controlled Toril.
They were also known as Eto, Attaw, and Giangan. Despite the forest dweller appellation, the Clatas who were feared warriors, were also known for their fine artistry.
They wore the most beautiful and colorful clothes in the Gulf.
The Bagobo origin myth of the first man and woman is of Giangan provenance. Tuglay, the Bagobo first man is a Clata word for man and Tuglibong, the Bagobo first woman, is a Clata word for woman.
