角齿鱼科（学名Ceratodontidae）是角齿鱼目唯一的科，只有一种，澳大利亚肺鱼，长达一米，最大可达1.5米，鳞片大，只有一个鳔，胸鳍和腹鳍有力。只生活在澳大利亚昆士兰州，所以也叫昆士兰肺鱼或澳洲肺鱼。比非洲肺鱼更原始，不能长期干旱。

The Queensland lungfish, Neoceratodus forsteri (also known as the Australian lungfish, Burnett salmon, and barramunda), is the sole surviving member of the family Ceratodontidae and order Ceratodontiformes. It is one of only six extant lungfish species in the world. Endemic to Australia, the Ceratodontidae are an ancient family belonging to the subclass Sarcopterygii, or fleshy-finned fishes.
