斑点楔齿蜥斑点楔齿蜥曾广泛分布在新西兰本岛及其周围的小岛上,它的长相类似于两亿年前的古爬行动物.四肢发达,颈部和背部长有鳞片壮嵴.斑点楔齿蜥的名称虽然带有"蜥"字,其实并不是蜥蜴,两者明显区别在于斑点楔齿蜥具有第三眼睑,两眼之间还有一个类似于松果状的眼,其功能不甚明了。成年雌体体长0.4 m左右,成年雄体体长0.6 m左右,体色呈灰色或橄榄绿色,体重在1 kg左右。斑点楔齿蜥的动作缓慢,却非常长寿,一般来说,寿命在100年以上的个体极为普遍。斑点楔齿蜥从出生到性成熟需要以上的时间。每年的1到3月是斑点楔齿蜥的发情交配期,而产卵却要到10月甚至12月,数量在5～18个,孵化期长达12～15个月,生育周期在两年左右,平均算来,雌斑点楔齿蜥每四年产一窝蛋,繁殖周期在爬行类动物中是最长的.斑点楔齿蜥生性好斗,所以它们总是单个生活在洞穴。洞不仅是每一只斑点楔齿蜥赖以遮风避雨的家,也是它们抵御侵略者的阵地,斑点楔齿蜥是夜行性动物,如果天气非常好的话，它们也很乐意在洞口晒晒太阳。由于斑点楔齿蜥的新陈代谢非常满,所以相对于其他动物来说,它们对食物的量的需求并不是很大,新西兰物产丰富足以源源不断提供给它们充足的食物。斑点楔齿蜥寿命长,适合在低温条件下生活,食物来源又比较充裕,却还是在1847年欧洲移民大量踏上新西兰岛后灭绝了。
