Whakakai is a genus of baleen whale from the Late Oligocene (Chattian) Kokoamu Greensand of New Zealand.

Classification

Phylogenetic analysis recovers Whakakai outside crown Mysticeti as the sister taxon of Horopeta.^[1]

Paleobiology

Whakakai has been recovered in the same deposits that have also yielded the primitive odontocetes Awamokoa, Austrosqualodon, Otekaikea, and Waipatia, the eomysticetids Matapanui, Tohoraata, Tokarahia, and Waharoa, and the balaenomorphs Mauicetus and Horopeta.
