Asian black bear
Biologically and morphologically, Asiatic black bears represent the beginning of the arboreal specializations attained by sloth bears and sun bears. Asiatic black bears have karyotypes nearly identical to those of the five other ursine bears, and, as is typical in the genus, they have 74 chromosomes. From an evolutionary perspective, Asiatic black bears are the least changed of Old World bears, with certain scientists arguing that it is likely that all other lineages of ursine bear stem from this species. Scientists have proposed that Asiatic black bears are either a surviving, albeit modified, form of "Ursus etruscus", specifically the early, small variety of the Middle Villafranchian (Upper Pliocene to Lower Pleistocene) or a larger form of "Ursus minimus", an extinct species that arose 4,000,000 years ago. With the exception of the age of the bones, it is often difficult to distinguish the remains of "Ursus minimus" with those of modern Asiatic black bears.
Sangu Matamuhari
The wildlife sanctuary was once covered with luxuriant multi-storied evergreen forest. The Asian elephant herds used to roam in and around the sanctuary. However, due to settlement of refuge, the vegetation of these areas diminished and became uninhabitable for elephants, which now can be seen in Sangu Mouza only. Asian black bear is the most common bear species in the area but still low numbered. Second bear species of the area is Sun bear Other large mammal sambar deer are also been reported here but in lower numbers. Just recent camera trap project captured some clouded leopard photos. Endangered species great hornbill are still seen flying in the sanctuary. There are some spotted owlet as well.
