What animals scare people most? Why?
The most common animals (and bugs) that people fear are:
Spiders, mice, moths, sharks, bees, certain dogs (mainly pit bulls, Rottweilers...), snakes, etc.
These fears can have any cause, such as evolutionary. With sharks, the fear is pretty self explanatory. But animals like spiders which are mainly harmless, may have been linked to many deaths a thousand years ago. Perhaps they used to be larger or more poisonous.
These fears can also rise from life experiences. If a little boy was attacked by a chow chow and had to be hospitalized, he likely will fear chow chows (or all other dogs in extreme cases) for a long time after his incident.
Fears of animals can arise when a person is surrounded by lots of people who are scared of that animal. For example, a child may develop a fear of snakes after she sees her mother panic around every snake they come across.
There also can be no apparent cause for the fear of that certain animal.
Personally, I have a major fear of spiders...
