A small, short-legged deer with a crouched build, the Visayan spotted deer is easily recognized by its namesake spots. The overall coat color is a very dark brown (sometimes with reddish highlights), but the sides are covered with a smattering of white or buff spots. These spots are largest over the hips and grow smaller and fainter towards the shoulders (at which point the coat becomes solid brown in color). The undersides and inside surfaces of the legs are white, as is the underside of the short tail. The head of the Visayan spotted deer is rather pointed. The head is usually paler than the body, although the forehead and muzzle are usually dark. Males grow short antlers (around 25 cm long) with three tines on each.

Similar species
- Visayan spotted deer are easily distinguished from other Philippine deer (Axis calamianensis and Rusa marianna) by the presence of spots in the adult coat.
- Fallow deer (Dama dama) and axis deer (Axis axis) both have spots as adults, but the rest of the coat is much paler in color than Visayan spotted deer.
Reproduction and Development
-
Gestation period: 8 months.
- Litter size: 1.
- Life span: Up to 20 years (in captivity).
- Litter size: 1.
Much is unknown about the life cycle of the Visayan spotted deer in the wild. Births in the wild have been recorded in March, May, and June, but young animals may be seen in all seasons. In captivity, babies may be born year-round. Like the adults, fawns are spotted. Males begin to grow antlers after their first birthday.

herd size may be due to human interference). Males may be solitary.
