椰子蟹学名Birgus latro)又称八卦蟹,是十足目陆寄居蟹科节肢动物无脊椎动物[2]。 其体重最高可达6公斤,是现存最大型的陆生甲壳动物。椰子蟹善于爬树,能爬到树顶觅食。[3]有人称椰子蟹为强盗蟹,传言它们会从民居和帐篷中偷窃罐和银器之类的东西,因此椰子蟹在世界上的族群已经愈来愈少了,台湾已将椰子蟹列入台湾保育物种列表中。

特性[编辑]

它们是一种寄居蟹,能用钳子弄破椰子的外壳,以吃其中的椰子果肉,并因以为其名。

椰子蟹多数出现于热带地区海岸与部分亚热带群岛海岸,通常在日本南方的伊豆群岛琉球群岛中可发现到。而台湾如东海岸、绿岛兰屿)及恒春半岛等地分布最多。另外世界上其他地方如印度洋太平洋热带岛屿亦有分布。

喜爱在中润湿繁殖,白天常躲藏于海边阴凉的树林石头珊瑚礁之下,晚间才出没觅食。食地瓜椰子木瓜花生等。椰子蟹会爬树,用鳃呼吸。椰子蟹是卵生动物,于海水中孵化。
