DAGUA - Most people have an instinctive fear of snakes, which is believed to be evolutionary. Researchers think the fear came about as a prehistoric survival mechanism but this does not explain why humans do not fear other predatory animals as much.
Ophidiophobia (also ophiophobia) is the word used to describe this human fear of snakes. It is a sub-category of herpetophobia, the general fear of reptiles like snakes and lizards.
There is mild ophidiophobia where any encounter with snakes brings fear. And there is extreme ophidiophobia in an abnormal fear of snakes.
In extreme ophidiophobia, sufferers develop physical and psychological stress when near snakes, shown images of snakes or told stories about snakes.
