Beasts of Prey
Predators have their senses and abilities adapted to help them as much as possible in hunting. Running goes without saying - some are sprint specialists, others have great stamina (some both). They see, hear and smell excellently (Perception at least 20 or more) and they also see at dusk or in the dark (darkness penalties 5 lower). Most of them are naturally capable of stealth and silent walking.
Predators are mostly interested in animals; they attack humans only in a tense situation, when threatened or when hungry (or when they feel strong, for example in a pack).
Active movement
Predators have simultaneous movement even while fighting.
Herbivores
Herbivorous animals of the wild are shy and cautious. Their senses are as developed as those of predators (and often even better), with eyes set on the sides of the head so they can see well all around, always ready to flee.
Large animals
Large animals such as the elephant or the rhinoceros are herbivorous in most cases, but they can be more dangerous than all predators combined (and indeed they are not fond of predators). Their senses vary; in general they are worse than those of predators and small animals (their strength and size protect them, they do not need to know about danger).
What is surprising about them is that despite their size they can run fast (almost always faster than a human).
Small animals
The Bestiary does not list animals that make no sense to fight: the hare, the beaver, the rat and the like. These creatures never attack a human, could not do anything to him anyway, and at most the characters will try to hunt them.
When shooting (fighting), take into account mainly the modifiers for size and movement.
