The male Amur Tiger can weigh as much as 318 kilograms (700 lb) or 350 kilograms (800 lb)or in rare cases 408kg (900 lb), a supposition based largely on the estimates of hunters. On average, a tigress weighs about 160 kilograms (350 lb), and a male weighs about 225 kilograms (500 lb). At these sizes, the Amur Tiger is the largest natural creature of the cat family, though not as large as the liger, a panthera hybrid only found in captivity. The largest captive Amur tiger was 3.7 metres (12 ft) long and weighed over 423 kilograms (932 lb), compared to the largest captive African lion that weighed 366 kilograms (806 lb).
