It’s unusual when we get consensus
If you look at three apex predators:
The Great White Shark
The Orca, or Killer Whale

and the Polar Bear, they all agree on what their favourite food is:
Seals.
Seals are unbelievably common in the wild, have few natural defences, and their bodies contain massive amounts of fat. All three of the above predators are easily capable of eating a 70kg seal in a single meal. In fact, all three have been known to REJECT human beings as prey because they’re not fatty enough – too much meat and bone which has less calorie value.
And speaking of humans
They know a high calorie meal when they see one too.
