The mouth shown for "herbivore" is a horse mouth and seems intentionally misleading. I own horses, they have fangs between their molars and incisors. Males generally have 4, females sometimes less. Arguably they are vestigial or there as weapons, but they are there. Also, I have seen my horses be opportunistic feeders often, they will absolutely eat baby chickens, frogs, mice, eggs, and insects.
