The bamboo finger rat ( Kannabateomys amblyonyx ) is a rodent in the spiny rat family . The species forms the monotypical genus Kannabateomys .
features
In contrast to many other spiny rats, the bamboo finger rat has a soft fur, without bristles or spines. The description of coat color varies between the existing treatises. According to Nowak (1999), yellow-brown tones with an orange shade dominate on the upper side, while the underside is light brown to white. Eisenberg & Redford (1992) , on the other hand, describe the fur color on the middle of the back as agouti gray-brown, on the sides of the body as red-brown and on the stomach and sides of the face as pink. The snout is characterized by an approximately square shape and long vibrissae . Another typical feature is the tail, which is well haired at the base, which is only covered with short hair in the middle and ends in a brush-like tassel .
The bamboo finger rat reaches a head-trunk length of 23 to 34.7 cm, a tail length of 30 to 42 cm and a weight of 350 to 570 g. The German name refers to the long and broad shape of the third and fourth fingers and the third and fourth toes. All fingers and toes have flat nails . There are further differences to the closely related species of the genus Dactylomys in the structure of the tooth enamel .
distribution
This rodent lives in southeastern Brazil and in adjacent areas of Paraguay , Uruguay and Argentina . Forests with a bamboo undergrowth near the Atlantic, rainforests , gallery forests and smaller areas covered with bamboo serve as habitats .
Way of life
The bamboo finger rat is mostly found singly or in pairs. The individuals establish a territory, whereby territories of different sexes overlap. Leaves and young shoots of bamboo plants and other plants serve as food. The animals predominantly climb in trees or in the bamboo undergrowth and build a larger nest in the branches.
This rodent is mainly active from dusk to dawn, but can occasionally look for food during the day. A monogamous reproduction is generally given for the species . Since there are several females in a male's territory, polygyne reproduction cannot be completely ruled out. The willingness of the female to mate is not tied to any season and there are one to three young animals per litter. The offspring are raised by both males and females.
The bamboo finger rat is believed to be hunted by the crested capuchin ( Sapajus apella ), although a killing has not yet been observed.
status
In some areas, deforestation, fires or dogs running freely can pose a threat to the bamboo finger rat. According to the IUCN, the entire population is not considered to be at risk ( least concern ).
