Hand-raising a spectral tarsier (Tarsius tarsier) at the Ueno Zoological Gardens.

On February 10, 2008, a newborn male spectral tarsier (Tarsius tarsier) was found on the floor of the indoor exhibit room in the Small Mammal House of the Ueno Zoological Gardens. The dam showed no signs of providing maternal care and therefore we decided to hand-raise the infant. Its birth weight was 18.
