Horsfield's treeshrew range

It was first described by Thomas Horsfield in 1822.^[3] Several subspecies have been proposed based on variation in colouration; however, colour is an unreliable distinguishing character.^[4]

Characteristics

There are many variations of papillae on the surface of the Horsfield's treeshrew's tongue, which depend on the food it eats as well as the pattern and function of its tongue.^[5] The Horsfield's treeshrew has a unique skull shape that better suits its environment and differs from other treeshrew species.^[6]

Behavior and ecology

The Horsfield's treeshrew eats fruits and insects while mostly consuming arthropods.^[5] It spreads plants seeds and controls insects, and therefore plays a significant role in the ecosystem; it has a special ability to adapt to agroforestry systems.^[7]
