Père David's Deer

Adults weigh 150-200 kg (330-440 pounds), and stand about 45 in (1.15 m) at the shoulders. They have a nine-month gestation period, and one or two fawns are born at a time. They reach maturity at about 14 months, and have been known to reach the age of 23 years.

Père David's Deer has a long tail, wide hooves, and branched antlers. Adults have summer coats that are bright red with a dark dorsal stripe, and dark gray winter coats. The fawns are spotted.

It is very fond of water, and swims well, spending long periods standing in water up to its shoulders. Although a predominant grazing animal, the deer supplements its grass diet with water plants in the summer.
