椰子蟹學名Birgus latro)又稱八卦蟹,是十足目陸寄居蟹科节肢动物。 其體重最高可達6公斤,是現存最大型的陸生节肢动物。椰子蟹善於爬樹,能爬到樹頂覓食。[2]有人稱椰子蟹為強盜蟹,因為傳言牠們會從民居和帳篷中偷竊罐和銀器之類的東西[3]

特性[编辑]

眾所周知,牠們是一種寄居蟹,能用鉗子弄破椰子的外殼,以吃其中的椰子果肉,並因以為其名。

椰子蟹多數出現於熱帶地區海岸與部分亞熱帶群島海岸,通常在日本南方的伊豆群島琉球群島中可發現到。而台灣如東海岸、綠島蘭嶼達悟語Tatos)及恆春半島等地分佈最多。另外世界上其它地方如印度洋太平洋熱帶島嶼亦有分佈。

喜愛在中潤濕繁殖,白天常躲藏於海邊陰涼的樹林石頭珊瑚礁之下,晚間才出沒覓食。食地瓜椰子木瓜花生等。椰子蟹會爬樹,用鰓呼吸。椰子蟹是卵生動物,於海水中孵化。
