Animals of Borneo Island

The Bornean orangutan, or Bornean orangutan, lives in the rainforests of Borneo and builds nests in dense foliage. The Bornean orangutan has a reddish-brown body with a large head and a high mouth. Bornean orangutans have protrusions on both sides of their faces to distinguish them from Sumatran orangutans.
This fish is called a freshwater dolphin, because it lives in rivers. The Mahakam dolphin has a round head with small eyes. The color of the skin is gray and also paler on the underside and there are no special distinctive patterns. There is no beak and broad, rounded pectoral fins.
Currently the Mahakam dolphin population continues to shrink due to traffic in the waters of the Mahakam River which is very busy and the high rate of erosion and also the silting of the river due to forest management in the vicinity. They have to compete with fishermen who work along the Mahakam River to find fish and shrimp.
