The Halmahera naked-backed fruit bat (Dobsonia crenulata) is a common and widespread species of megabat in the family Pteropodidae. It is endemic to Indonesia. "Non-Moluccan populations apparently represent an undescribed subspecies (K. Helgen pers. comm.). The species is found in Indonesia, in northern Moluccas, Togian Islands, Sangihe Islands, Talaud Islands, Pelang, and Sulawesi and other Indonesian islands (Muno, Buton, Peleng, Kabaena, Mangole, Sanana, Halmahera, Siau, Sangihe, Karekelang and also Hoga Island). It is commonly found in gardens and disturbed forest (Flannery 1995). It is not dependent on water. It roosts in caves, trees, and rock crevices. This species lives in large colonies. Births probably take place in December (Flannery 1995)."
