Apex predators possess no known enemies. They hunt without fear, roaming freely through their domain with the knowledge that no other animal can take what they want. Their carnal intuition enables them to attack with reservation, and they own their world to the degree that they survive for generations without fear or submission to any other species.
In the jungle, they operate with a skilled, quiet mentality that lurks in the shadows. They aren't sneaky, but their prey never sees the full scale of their violence coming. They only become the aftermath left on display as a warning for other animals to witness.
