species. Species The lowland anoa (Bubalus depressicornis) is a small bovid, standing barely over at the shoulder. It is usually solitary, living in lowland forests, browsing on plants and understory. According to the Groves (1969) the lowland anoa can be told apart from the other species by being larger, having a triangular horn cross-section, sparse as opposed to thick and woolly hair, and always having white marking on the face and legs. The mountain anoa (Bubalus quarlesi) is also known as Quarle's anoa and anoa pegunungan. Standing at at the shoulder, it is even smaller than the lowland anoa and the smallest of all living wild cattle. They also have longer, woolier hair that moults every year, showing faint spots on the head, neck and limbs. According to the Groves (1969) the mountain anoa can be told apart from the other species by being smaller, having a round horn cross-section, thick and woolly hair, and sometimes having white marking on the face and legs. Distribution Both the lowland anoa (Bubalus depressicornis) and the mountain anoa (Bubalus quarlesi) are endemic to the islands of Sulawesi in Indonesia. Both species appear to occur in exactly the same areas. Sulawesi is a unique area due to the fact that roughly 61% of the species found there are endemic species, including both anoa species. Habitat Traditionally, a key difference between the two species is the altitude at which they occur. The mountain anoa would be found at higher elevations than its lowland counterpart and is found in the forests. The lowland anoa was said to spend its time in the lower elevation areas and is also found in forests. Since 2005, however, these differences do not seem to be accurate, both species occur in the same areas in the same habitats. Morphology The anoa have many physical characteristics of bovine relatives and are considered to be most closely related to the water buffalo, which was confirmed through DNA analysis. The physical characteristics of the two species are similar. The anoa is the smallest of the wild cattle species. When anoa are born, they have a set of thick, woolly fur that comes in many color variations ranging from yellow to brown. In adults, the fur is typically brown or black and males tend to have darker variations. Hair thickness varies slightly between the two species based on elevation and distribution. In both species of
