Taxonomy
Blainville named the species Delphinus densirostris, based on the description of a nine-inch piece of rostrum of unknown origin housed in the Paris Museum. The second specimen, a complete skull sent from the Seychelles by a M. Leduc in 1839, was named Ziphius seychellensis by the English zoologist John Edward Gray in 1846; the French scientist Paul Gervais later placed this specimen in the genus Dioplodon ("two-toothed").
