词条 | flying lemur |
释义 | flying lemur mammal also called colugo ![]() Besides the Philippine species, Cynocephalus volans, a series of races of Cynocephalus variegatus ranges from Myanmar (Burma) to the Malay Peninsula and from the islands of Sumatra to Borneo. Flying lemurs were formerly classified as insectivores (insectivore), but they differ from them and from other mammals in several basic anatomical features, especially in the form of the brain and in the dentition. The teeth (34) are peculiar in that the lower incisors stick out in a comblike structure formed of enamel folds; the second upper incisors are similar to canine teeth and are double-rooted. Canines are absent in the upper jaw. Cheek teeth (premolars and molars) bear sharp cusps. The digestive tract exhibits specializations to a strict vegetarian diet. Although flying lemurs share some characteristics with certain bats (flying foxes (flying fox) of suborder Megachiroptera), they are most closely related to the primates. |
