Carnivores have such mighty weapons they can’t really afford to use them for relatively irrelevant fighting, instead they use threats

A lion (to pick one example of a carnivore) could risk death if it risked actually using its teeth in irrelevant fighting. Instead they only show their teeth and snarl. Actually using their teeth is only when it is actually about life or death in fights.
The exact opposite applies to vegetarians, zebras and giraffes being taken as examples

Giraffes have almost no teeth but they use the well known necking where the head becomes a sledgehammer
Gorillas only use threats charging towards the trespasser

They charge towards the trespasser, indicating that this region is already taken !!!
