The DTGReviews has made a list of some of the most dangerous Animals in the game. Check out them below, and learn how to act against each of them.
Leopards, Dogs and Wolves
These are fast animals, attacking quickly and intelligently, especially if the game is on the hardest level. You need to be very careful with them, and the way it can be more efficient to use weapons with fast shooting and reloading, because animals usually attack in flocks.
Demon Fish / Tigerfish
Demon Fish is most difficult animals to deal with, because if it appears in front of the water, there is nothing you can do - after all, it is impossible to shoot out of the water. So avoid, when possible, swimming without paying attention to your surroundings. And if it appears, try going to one of the nearby banks, and shoot from there.
Rhinos and Elephants
Not worth wasting time with these animals. Have thick skin, are hard to miss damage, and may end up killing you. On the other hand, are relatively slow. The ideal behavior is to avoid them.

Eagles, Bees and Snakes

Bees attack in groups and are very fast, but you can use them to your advantage. Look for hives close to enemies and drop on them. The snakes are too difficult to see, poison and flee. Against them, there is nothing that is very effective. It is better to run.
Tigers and Bears
Two Animals styles a little different, but they have a similarity: the strong attack. The tiger is faster, while the bear is slow. However, the best way to stop them is using long range weapons. So you can avoid partially the damage.
