There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Its total length has been estimated to be about 13,5-17,5 m similar to moderns sperm whale (Physeter macrocephalus), making it  one of the largest predators to have ever existed. The tallest tooth measured 36,2 cm it is the largest tooth of any 
 known animal, excluding tusks. It is distinguished from the other raptorial sperm whales by the basin on the skull, and how it spans the entire length of the snout. 
The holotype skull of Livyatan was about 3 m long, like other raptorial sperm whales, Livyatan has a wide gap in between  the temporal fossae on the sides of the skull and zygomatic processes on the front of the skull, indicating a large spece for holdind strong temporal muscles, which are the most powerful muscles between the skull and the jaw. 
Unlike the modern sperm whale, Livyatan had functional teeth in both jaws. The wearing on the teeth indicated that the teeth sheared past each other while biting down, meaning it could bite
off large portions of flesh from its prey. also the lower jaw contained 22 teeth and upper jaw contained 18 teeth.
