Cetaceans are the fifth mammal generator, and the twenty-eighth generator overall. They were officially added in Steam patch 7.86.
With a modest unlocking cost and several very potent upgrades, Cetaceans are useful in gathering enough Metabits to unlock Feliforms, if the player has not yet developed the Mesozoic Valley far enough to unlock Neoaves.
Cetaceans are aquatic mammals that are descended from the same ancestors as ungulates. While some ungulates moved further inland, the cetaceans inhabited the shoreline and later moved into a fully aquatic niche.
Cetaceans take the appearance of a whale, either a blue whale or a humpback whale.
All upgrades only require one generator to purchase, in addition to the requirements below.

Dolphins are a 3D trophy, and have a generation sequence, similar to generators.
