The baiji (or Chinese River Dolphin) is believed to be the rarest mammal, although lack of sightings in the wild have lead to whispers of the baiji now being extinct. Following the baiji, the Javan rhinoceros is also exceptionally rare.
The right whale is the rarest because whalers called it that because it was slow, it had lots of oil and lots of meat. Next is the sperm whale because its rectangle head contained 1000 kg of oil.
