The dwarf spinner dolphin may feed mostly on benthic fish in reefs and shallow water. [7]

A phylogenetic analysis in 2006 indicated the two species traditionally assigned to the genus Lagenorhynchus, the hourglass dolphin L. cruciger and Peale's dolphin L. australis are actually phylogenetically nested among the species of Cephalorhynchus, and they suggest these two species should be transferred to the genus Cephalorhynchus. Some ...
