Do not approach unfamiliar animals even though they are tame or friendly looking. Stay calm and do not scream when an animal is approaching towards you.
Such as defence against the gorilla Behave submissively. Crouch down rather than standing over them, and stay in a close group. Talk in whispers. Look at them sideways, not straight on. Remember that gorillas do not eat meat, but are also not harmless. They are wild animals, and very protective of their family and space. When attacked: Curl into a ball to protect yourself
Yelling for help is usually a good idea. You should ideally be traveling in groups. You should be standing up straight and make yourself big. Do not turn your back on the animal. You should keep watching the animal, but in some cases it is best not to stare. The idea is not to start an attack if you don't have to. If you can, start backing away and heading to safety. Throw things and generally let the animal know it would be bad for them to attack. In some of these cases, animals attack to protect their cubs so make sure you're not standing between them and their young.
