Not only was Livyatan an apex predator like C.‭ ‬megalodon,‭ ‬it probably fed upon the same prey animals which were medium sized baleen whales.‭ ‬Smaller juvenile Livyatan may have preferred proportionately smaller prey items like the smaller cetaceans or even large fish.‭ ‬With teeth that were thirty-six centimetres long,‭ ‬Livyatan had the dentition to take down large prey items.‭ ‬In fact not only were the teeth of Livyatan considerably larger than C.‭ ‬megalodon teeth,‭ ‬they are considered to be the largest known teeth for the purpose of eating.‭ ‬Granted some animals like elephant have modified teeth that form tusks which are even bigger,‭ ‬but they are useless for processing food in the mouth so in this case they do not count as the largest.‭ ‬Livyatan also had teeth in both the upper and lower jaws for grasping prey‭ (‬the modern sperm whale,‭ ‬the closest living analogy to Livyatan,‭ ‬only has teeth on the lower jaw‭)‬.
