俄罗斯最新一次测量体重结果:10头雌虎,平均体重119.1kg,平均体长173cm,尾长91cm,体全长264cm;12头雄虎,大部分健康个体体重在180~210公斤之间,平均平均体重169.5公斤,体 。野生东北虎最大个体的体重纪录是350公斤,并载入《苏联哺乳动物》书籍中,被认为是最大的野生猫科动物的吉尼斯世界纪录,此外还有300公斤、310公斤、300公斤、350公斤(权威猫科动物学者Mazak引用)等个体实例,都收录于各动物学专著,但是现代西方以及俄罗斯学术界对于这些数据提出很多质疑。虽然这些巨大的个体始终作为历史记录而存在,但仅在历史纪录当中,并不被现代科学家所认可;此外,一些狩猎记录更为夸张,包括被很多网站提到过的700公斤实例,却没有测量的任何出处,可能是误将700磅当成公斤,搞错了单位。人工饲养的雄虎体重吉尼斯纪录为1025磅(465公斤)于1986年实测,二十多年过去,有不少圈养虎超过了这个记录,包括一些动物繁殖中心和动物园,有关详细报道了300公斤、268公斤的实例,甚至现了一个混血虎的重量更大纪录,达到350公斤,这些数据的真实性没有得到权威认可,老虎的健康也得到了质疑。雄东北虎头骨长为 东北虎340-360mm之间, 最大的,也只有383mm,以前有文献说在哈尔滨有一个400mm长的头骨。1959年冬天,一头西伯利亚虎杀死了在一头带仔成年雌北极熊,并吃掉了小熊和母熊;1956年3岁年轻公虎杀死并吃掉了一头棕熊;1961年一头棕熊被虎杀死并吃掉;1957年母虎杀死一头棕熊和它的三岁幼仔。成年虎是没有天敌的,但是在很罕见的情况下会由于野牛袭击受伤致死。1913年一头成年公虎杀死了大棕熊。1981年一头体型大的棕熊跟踪一只公虎,最后倒反被公虎杀死并吃掉了,而相反的一个例子发生在1960年的阿林地区,棕熊成功杀死了母虎,并吃掉了它。身长 ,头-躯干, 雄170-280cm 雌尾长: 8-14cm 。体重 ,通常雄: 540kg~650kg 雌: 150kg~300kg但体形大的个体并不少见,不少的雄性能达到600kg,而且过冬前的体重会比平时大得多。棕熊是陆地上体形第二大的食肉动物,在夏季进食之后,体重会增加一倍,成年棕熊可达650公斤,最大可以达到800公斤还行吧。

棕熊好像是能达到4-500公斤,老虎可能2-300吧
