夜蝰亞科
Sign in to saveCausus is a genus of vipers found only in sub-Saharan Africa. It is a group considered to be among the most primitive members of the family Viperidae based on head scalation, oviparity, venom apparatus, and because they have round pupils. However, this is contradicted by recent molecular studies. Seven species are currently recognized as being valid. They are commonly known as night adders. Like all other vipers, they are venomous.

夜蝰亞科（學名：Causinae）是爬蟲綱有鱗目蛇亞目蝰蛇科下的一個單型亞科，科下主要包括分布於撒哈拉以南非洲地區的有毒蝰蛇。夜蝰亞科是為了夜蝰屬（Causus）而特別設立的一個亞科，而這些夜蝰是根據牠們於鱗片結構、卵生形態、毒素分泌等各方面的獨特性，並且有著圓形瞳孔，因而被獨立出來的一種原始蝰蛇。目前夜蝰屬下共有六個種已被確認。
