Cetotherium (SciiFii)

Not to be confused with a subspecies of blue whale, pygmy blue whale.

The dwarf blue whale (Cetotherium modernus, name meaning "modern whale beast") is a species of baleen whale of the family Cetotheriidae, closely related to the pygmy right whale, also a cetothere. It originally lived from the Middle Miocene to the early Pliocene and was once extinct, but has since been brought back from extinction by SciiFii and introduced to the modern Pacific and Indian Ocean to restore the declining biodiversity. It is rather small compared with most other baleen whales, only growing to be around ‬4.5‭ ‬meters long. Like most other baleen whales, it is a gentle filter-feeder that mainly feeds on krill and schools of small fish. It has a social lifestyle that resembles a cross between those of pygmy right whales and those of humpback whales. The conservation status of the dwarf blue whale is Least Concern due to successful conservation efforts.
