【非洲大蜗牛科】
非洲大蜗牛科又名玛瑙螺科（学名：Achatinidae）包括超过100个属，都是原生于非洲的大型和中型陆生蜗牛，成蜗每年可以产3-6次卵，每次产卵因体形不同，每次产卵约50-500颗。
== 分布 ==
该科的蜗牛分布于撒哈拉以南非洲。
== 解剖学 ==
该科蜗牛的单倍体染色体大约有26到30。
== 分类学 ==
该科分类在非正式群体弯尿道亚目下，属于柄眼亚目、真肺目，下领四个亚科。
2017年，根据《布歇特等人的腹足类分类》，原来柄眼目之下的四大分类重组，本科成为了玛瑙螺亚目的成员之余，下领八个亚科的钻头螺科亦被并入本科。因此，非洲大蜗牛科成为了一个下领12个亚科的庞大分类，而不少亚科之下又再细分为多个族。
