黄头侧颈龟学名Podocnemis unifilis英语yellow-spotted Amazon river turtle, yellow-headed sideneck turtle),俗称忍者龟,是南美侧颈龟科南美侧颈龟属的一种,生活在 河流或湖泊地区,分布于委内瑞拉、哥伦比亚、厄瓜多尔、秘鲁、圭亚那等地。黄头侧颈龟因头部的黄色斑点而得名,幼时甲色扁向绿色及棕色,而头部的黄色斑点颜色会比较鲜艳,长大后雌性的斑点颜色会变淡,而雄性则会保持鲜艳,同时两性的背甲都会转为灰黑色。牠们的平均寿命是60至70岁。

现况

[编辑]

忍者龟在台湾及香港的市场也深受欢迎, 不可放生于野外, 因为承受不了寒冷冬天的天气;而于野外的个体则分布于委内瑞拉哥伦比亚厄瓜多尔秘鲁圭亚那等地,身体长度最长可达30-45cm。

习性

[编辑]

忍者龟并不能抵受低温,水温大概达18℃左右食量便会减少,水温10℃左右便会冬眠,长期处于低温的环境下便有机会生病, 最好能在25C 的环境。同时,牠们扁向杂食性,会吃植物果实及水果,也会进食鱼类。

繁殖

[编辑]

雌龟每年可产两窝蛋,每次4-35枚。他们会把巢建在沙区,卵会在产下66天至159天孵后化。产卵的高峰期在旱季,使巢不会被雨季的洪水冲走。
