The family Callorhincidae (sometimes spelled "Callorhynchidae"), or plough-nose chimaeras, are a family of marine fish. They are similar in form and habits to other chimaeras, but are distinguished by the presence of an elongated and flexible fleshy snout, with a vague resemblance to a ploughshare. The snout is used to probe the sea bottom in search of the invertebrates and small fishes on which it preys.

Plough-nose chimaeras are found only in the oceans of the southern hemisphere, and range from about 90 centimetres (3 ft) to 125 centimetres (4.1 ft) in total length.


The family contains three species, all in the same genus:
  • Callorhinchus callorynchus
