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 actually used its teeth in irrelevant fighting. Instead they only show their teeth and snarl. Actually using their teeth is only when it is really is 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 when they charge towards a trespasser
They charge towards the trespasser, indicating that this region is already taken !!!
