Alligators + Crocodiles:
Run away in a zig-zag pattern NOT in a straight line. The animal has to slow down to turn as it has short legs.
Run downhill. A bear has to crawl down a hill because of its two short front legs and it has to slow down.
Do not stare an angry dog in the eyes and do not run away. Curl up in a ball and cover your neck with your hands. They will lose interest and leave.
Get out of the elephant's line of vision. Hide behind a tree, if possible. Keep zig-zagging from tree to tree if it still shows interest in you. If it can't see you, it usually calms down.
Do NOT run away and do NOT stare into its eyes. Look at the ground and be humble. It will walk away.
Stare it down. Do NOT swim away because it will be attracted to your movements. If it attacks you, gauge it in the eyes with your thumb (not your fingers because they are weaker).
