加拉帕戈斯象龟（学名：Chelonoidis nigra）是现存体型最大的陆龟之一。为厄瓜多尔加拉帕戈斯群岛特有。成年象龟身长1.5 米(4.9英尺)，平均体重达到175千克，最高纪录为400千克(880磅)，在爬虫类中列第13位。野外寿命超过100年。2006年6月23日在澳洲动物园因心脏衰竭病逝的大象龟哈丽，估计享年约175岁，病逝前为世上最长寿的存活动物。

由于加拉帕戈斯群岛中不同岛上的生态环境有明显的差异，故不同亚种的象龟形态都不同。在湿润的高地岛，象龟更大，有半球形的壳和短脖子，在干燥的低地岛，象龟更小，有马鞍形的壳和长脖子。这启发出达尔文对“进化论”的思考。

近年这些群岛上各品种之间的关系存在争议，故现时将加拉帕戈斯象龟归类为一个物种综合（species complex），而非单一物种。

16世纪加拉帕戈斯象龟的数量大约有25万只，1970年代只剩下3000只，主要原因是人的捕猎以获取肉和油，栖息地被农业生产占用和物种入侵，如羊和猪。原有的15个亚种还剩十个亚种在野外生存，第十一个亚种只剩一只名为“孤独乔治”的雄龟，于2012年6月死亡。20世纪初开始的动物保护活动使象龟现有的数量回复到1.9万只。在国际自然保护联盟名录中属于易危物种。

分布与栖息地编辑

各亚种分布：灰色表示尚有原生象龟的岛屿，但分布极西的费尔南迪纳岛象龟于2019年重新被发现

加拉帕戈斯象龟只分布于南美洲加拉帕戈斯群岛的9个小岛上。为适应各岛上不同的环境以及食物来源，象龟在数百万年间分化成15个亚种，现在仅约10种还有野外存活的个体，最近绝种的品种平塔岛象龟（C. n. abingdoni）曾长期只剩一只名为“孤独乔治”的雄龟。加拉巴戈斯国家公园（Galapagos National ParkService）于2012年6月24日发出声明，“孤独乔治”已经死亡。在6月24号当日，长久以来一直照顾“孤独乔治”的勒里纳（Fausto Llerena）发现它的尸体瘫在地上，面朝圣克鲁斯岛（Santa Cruz Island）上“它水坑的所在方向”。^[16]

习性编辑

龟是变温动物，因此在阳光下晒1-2小时，吸收太阳的热量，而天亮后他们会透过爬树积极觅食。它们每天睡8-9小时，大多在清晨或傍晚休息。同时，它们的行走速度为每小时0.3公里（0.2英里）。

在较大、较潮湿及低海拔的岛屿上，龟之间会出现季节性迁移，在干燥的季节，它们会迁移到海拔较高（610米）的草原地区。同一路线已出现了很长时间，创造良好行走的路径，而被乌龟通过的灌木丛被称为“乌龟公路”。

在凉爽的夜晚，加拉帕戈斯象龟会会在泥泞的及雨水形成的池中休息，这可能是由于需要进行体温调节和驱赶寄生虫。亦有些龟会在伸出的岩石下休息。

饮食编辑

加拉帕戈斯象龟是草食动物，食物包括仙人掌、草、树叶、苔藓和浆果等。一只乌龟平均每天吃32-36千克（70-80磅）的食物，但因消化系统的效率较低，因此摄取的营养也较少。

陆龟以植物的露水和汁液获得大部分水分，因此，他们可以在很长时间内不喝水。他们也可以忍受长达18个月的时间不进食不喝水；而口渴时，他们喝水的速度可以既大量又快速，并储在自己的膀胱及心脏，使他们在长时间内不用再喝水。在干旱的岛屿上，象龟会在清晨时舔舐巨石上的露水，许多岩石上已形成因连续多代的此类行为所造成的岩石凹陷。

濒危原因编辑

在达尔文初到加拉帕戈斯群岛时，加拉帕戈斯象龟的数量大约有25万只，现在却只剩下1万9千只。数量剧降的最主要原因是18至19世纪的捕鲸者及海盗经常捕捉象龟作为在船上的粮食。

保护状况编辑

加拉帕戈斯群岛现已受到厄瓜多尔政府保护，列为国家公园，也是世界自然遗产。
