MEASUREMENT AND WEIGHT- Editorial Comment

Editorial Comment

(Editorial Overview Text Replicated on Overall Species page - Ursus thibetanus - Asiatic black bear)

LENGTH
Adult: 
Head and body length of males is about 1.2 - 1.8 m (4 ft to 6ft); a very large male reached 1.95 m (6 ft 5 inches). Females are smaller, to 1.5 m (five ft) or perhaps 1.7 m (5ft 6 ins).
Newborns: Two cubs a few days old measured 26.5 cm.

HEIGHT
Adults and sub-adults: Shoulder height 0.7 - 1.0 m (2.3 - 3.3 ft).
Juveniles: --

WEIGHT
Adult: 
Males are generally larger than females and are particularly heavy in autumn (fall). Males may weigh 60 to 200 kg (132 - 441 lb) with the highest weights being autumn weights; they average about 90 - 115 kg (200 - 250 lb). Females may weigh 40 - 140 kg (88 - 309 lb) but 65 - 90 kg is probably usual.
Newborns: Newborn cubs may weigh 300 - 450 g.

GROWTH RATE: Cubs in zoos reached on average 3.5 kg at three months.
