Cougar. Bears don't stalk you, and they atleast square off before they attack. Cougars, though definatley more rare, were relatively common where I grew up, and seeing warning signs posted on trails was pretty normal. Always stop and check behind you from time to time when hiking. Cats don't like it when their prey is aware of them.
I believe you but I did read that once in a while younger inexperienced bears do stalk humans and if they do it means they intend to attack. The advice given in that situation is to take the offensive because you do not want to behave like prey. If I am unarmed that may prove a bit difficult. This advice was given by a maker of bear spray who himself was mauled by a bear and saved by spraying it with his mace.
Back on topic. I don't fancy getting ripped apart limb by limb and my genitalia torn off by a crazed chimp but after seeing the movie anaconda and reading it's informative words about how they regurgitate their first meal to empty their stomach so they can enjoy constricting and swallowing another prey I am not so sure. They grow up to 40 feet long and unlike most animals are not picky about eating humans.
------------------------------------------------------------------------
Well it seems after doing a quick google search the movies description of anacondas and what is known in real life about anacondas is quite different they typically grow up to about 17 feet and humans are not on the menu they like to eat aquatic creatures. They are also shy recluses.
------------------------------------------------------------------------------------------
Are there any tips on how avoid being their next meal if you are in the jungle. Is there any easy way to kill or repulse them?
-----------------------------------------------------------
My quick google search reveals they are probably unable to eat humans oh what a relief. What a bunch of BS that movie is.
Thank you dttomcat for the heads up.

I have also read cats (such as cougars) are super dangerous expert stalkers that are rarely spotted by the untrained before it is too late. I am not sure if this is a positive note but they know how to kill you quite quickly.
