Introduction
The extent to which representitives of this family enter Australian waters is poorly known. Australophocaena dioptrica is usually associated with the temperate and cold water coasts of South America. Members of this family are generally estuarine and neritic.
The cranium is inflated and the jaws are not beaked. The spade-like teeth have two or three lobed crowns. The dorsal fin is usually triangular and located about mid-way down the dorsum. Between three and seven cervical vertebrae may be fused.
They are gregarious, but group size apears to be usually less than twenty individuals. The diet is mainly schooling fish and squid.
The species Phoecoena spinipinnis Burmeister, 1865 was reported from Heard Island (Guiler et al. 1987), but the specimen has since been reidentified as Australophoecaena dioptrica (Brownell et al. 1989).
