The Vordermann flying squirrel ( Petinomys vorermanni ) is a species from the genus of the dwarf flying squirrel ( Petinomys ). It occurs in isolated areas of mainland Southeast Asia in Myanmar and the Malaysia Peninsula, as well as on the islands of Sumatra and northern Borneo .
features
The front man's flying squirrel reaches a head-torso length of around 10 to 12 centimeters and a tail length of around 9 to 11 centimeters. The weight is around 35 to 40 grams. It is one of the smallest species of flying squirrel. The back color is brown, one specimen caught in Malaysia had white spots on its back. The eyes are clearly on the front of the head for a three-dimensional view.
Like all dwarf gliding squirrels, it has a hairy skin that connects the wrists and ankles and is enlarged by a fold of skin between the hind legs and the base of the tail. The sliding skin is muscular and reinforced at the edge, it can be tensed and relaxed accordingly in order to control the direction of the gliding flight.
distribution
The front-flying squirrel lives in isolated areas of the Southeast Asian mainland in southern Myanmar and perhaps also in Thailand north of the Isthmus of Kra as well as on the peninsula Malaysia and on the islands of Sumatra , Indonesia , and in the north and center of the island of Borneo with the Malaysian state of Sarawak and Sabah , the Indonesian part (Kalimantan) and the Sultanate of Brunei . A wider range is possible as the species is often overlooked in surveys due to its size and hidden way of life in the trees.
Way of life
The Vordermann's flying squirrel lives mainly in the tropical primary forest , but is also known from rubber plantations and swamp forests. There are only a few data and observations about the way of life of the flying squirrel. In its way of life it probably corresponds to other flying squirrels and is strictly arboreal, largely nocturnal and feeds on plants.
Systematics
The Vordermann flying squirrel is classified as an independent species within the genus of the dwarf flying squirrel ( Petinomys ), which contains a total of nine species. The first scientific description comes from Fredericus Anna Jentink from 1890 on the basis of an individual from the island of Belitung , Indonesia. According to individual authors, a classification of the species into its own, then monotypical , genus was proposed.
No subspecies are distinguished within the species .
Existence, endangerment and protection
The flying squirrel in front is listed by the International Union for Conservation of Nature and Natural Resources (IUCN) as endangered ("vulnerable"). This status is justified by the significant decline in the past and foreseeable future, which is greater than 30% of the total. This is attributed to the loss of habitat due to the conversion of forests into agricultural areas as well as the logging in most of its range.
