東部灰大袋鼠（學名：Macropus giganteus）又名東部灰袋鼠，为袋鼠科大袋鼠属的一种，是澳洲南部及東部的袋鼠，數量約有700萬。牠們一般重約66公斤，站立時約2米高。 目录 1 特徵 2 繁殖 3 生態 4 速度 5 保育狀況 6 參考文献 7 外部链接 特徵 東部灰大袋鼠主要呈淺灰色或褐灰色，腹部呈銀色或奶白色，有些甚至是白色的。東部灰大袋鼠與西部灰大袋鼠很難分辨，牠們有著非常相似的外觀及面部結構，吻部也同樣有幼毛覆蓋。[2] 繁殖 東部灰大袋鼠全年都會繁殖。雌性是胚胎滯育的，即可以延後下一胎的出生，直至前一胎的幼袋鼠離開育幼袋。不同於有胎盤的哺乳動物，袋鼠的幼崽沒發育多久就會被生下來。剛出生的幼崽基本沒發育完全，身上無毛，四肢短小，非常無助。它得沿著雌袋鼠的腹部爬到袋子裡，在那繼續發育。等它大點了，它不能直接鑽進袋裡的時候，它會先把頭鑽進去，在裡面翻個身，腿部進去，然後從裡面探出頭來。 生態 東部灰大袋鼠分佈在近大城市的南部及東岸。牠們棲息在遼闊的草原，日間以叢林作為遮蔭。牠們是夜間或暮晨活動的。在一些偏遠地區，東部灰大袋鼠是以大群聚居的。 速度 東部灰大袋鼠可以移動得很快，最高紀錄達每小時64公里。[3] 保育狀況 有指自歐洲殖民澳洲後，袋鼠因草原的增加、澳洲野犬的減少及人工水井的出現而數量大幅上升。[4][5]現時估計東部灰大袋鼠就有200萬隻。[6]故在一些地區出現宰殺東部灰大袋鼠的情況。[4][5]雖然東部灰大袋鼠的數量仍很多，但也已從一些地區絕跡。 參考文献 ^ Macropus giganteus.

Encyclopedic overview
The eastern grey kangaroo (Macropus giganteus: gigantic large-foot; also great grey kangaroo or forester kangaroo) is a marsupial found in the eastern third of Australia, with a population of several million. Although a large M. giganteus kangaroo male can typically weigh up to 69 kg (152 lb) and have a length of well over 2 m (6 ft 7 in), the scientific name is misleading as the red kangaroo of the semi-arid inland is larger, weighing up to 90 kg (200 lb).
