The single member of this family, the pygmy right whale (Caperea marginata), is found in the cold-temperate waters of the southern hemisphere. Usually included in the family Balaenidae in the past, they differ from members of that family in several ways. They are small, only up to about 6 m. The body is gray, lacking the striking black and white markings common in balaenids. Caperea marginata has, however, a strikingly white mouth and tongue. It also has a small, falcate dorsal fin.

 

This species is poorly known. It probably does not school or migrate long distances. It is believed to feed on copepods. The species is too uncommon to have been of much importance to commercial whalers.
