The Java pointed squirrel ( Tupaia hypochrysa ) is endemic to the west of the Indonesian island of Java .
features
The Java pointed squirrel reaches a head-trunk length of about 14.5 cm, has a tail of about the same length, about 3.5 cm long ears and 4.8 to 4.9 cm long hind feet. The weight of the animals has not yet been determined. The color of the top is brown aguti-colored (ie the hair is banded), the belly is tan to orange. The skull is large and wide and not elongated as in the Tana ( Tupaia tana ) and the Mindanao shrewfish ( Tupaia everetti ). The females have four teats.
Way of life
The Java pointed squirrel occurs in the few remaining rainforests up to heights of 2000 meters in western Java. There is also some evidence from secondary forests , plantations and orchards. So far nothing is known about the behavior, the way of life, the diet, the activity patterns and the reproduction of the Java shrew. It is likely diurnal and other shrews will feed on insects and fruits in particular.
Systematics
The Java pointed squirrel was scientifically described for the first time in 1895 by the British zoologist Oldfield Thomas as a subspecies of the reddish pointed squirrel ( Tupaia ferroginea ). Later, like the reddish pointed squirrel, it was assigned to the common pointed squirrel ( Tupaia glis ) as a subspecies. Exact morphometric studies of the proportions of the hands ultimately led to the Java shrewfish being recognized as an independent species.
Danger
No precise information can be given about the population and the endangerment of the Java pointed squirrel because too little data is available. Its remaining range in the west of Java is very small.
