Many distinctive forms of plant and animal life are found. Forestlands support hardwoods (notably teak), pine, bamboos, and betel and coconut palms; in the coastal lowlands, mangroves and rattan abound. Among the larger mammals are the bear, otter, and civet cat. Climbing animals include the gibbon and many species of monkeys. There are also sheep, goats, oxen, single-horned rhinoceroses, deer, tapirs, wild cattle, wild hogs, and snakes. There are over 600 breeding bird species. Crocodiles, lizards, and turtles are numerous. Fish abound in the rivers and coastal waters.
