蛇颈龟科（Chelidae），亦称侧颈龟科是龟鳖目下侧颈龟亚目现存的三科之一。^[2]该科龟类分布于澳大利亚、新几内亚、印度尼西亚部分地区和南美洲大部分地区。该科是龟鳖目下的一个大科，化石历史可以追溯到白垩纪。该科龟类全部（包括现存物种及化石）位于从前的冈瓦纳大陆，此外的其他地区没有发现任何蛇颈龟科动物。^[3]

描述

像所有的侧颈亚目龟类一样，该科龟类的脖颈缩回时全部侧向折回。

该科最小的物种包括16厘米（6.3英寸）长的墨累澳龟、^[4]18厘米（7.1英寸）长的南美扁头龟和15厘米（5.9英寸）长的澳洲短颈龟，最大的物种则有枫叶龟和白喉癞颈龟，二者的背壳长度都可达45厘米（18英寸）。^[5]

壳

蛇颈龟科的背壳都很独特，^[6]原因可能是他们不需要大的背最长肌。^[7]同时其背壳也很坚固，这是其一种保护机制，增加了对外界冲击的抵抗力，但也有人认为这是为了这与其进食方式和其他一些因素有关系。^[7]
