體型

[编辑]

東部低地大猩猩是現存最大的靈長目動物。最大野生的雄性可以重超過225公斤及高1.83米,而飼養的則可以更大。

行為

[编辑]

東部低地大猩猩是群居及和平的,一般以5-30頭大猩猩為一族群。一群中包含一頭雄性領袖及幾頭雌性。雄性領袖強壯,是群族中的領袖。牠會帶領族群尋找食物,並在危險時保護牠們。雄性達至成熟後會逐漸離開族群,與其他雄性一同生活幾年,直至能吸引雌性組成新的族群。

生殖

[编辑]

雌性每胎只每誕下一胎或雙生兒,妊娠期為8.5個月。牠會乳養猩猩嬰兒約12個月。嬰兒在9週後可以爬行,35週後則可以行走。猩猩嬰兒會伴在母親身邊3-4年,約要11-12歲才會性成熟。
