There are at least 50,000 spider species in the arachnid family. Even though spiders do a great deal of good for our environment, spiders are greatly feared by most of the population. Most spiders are killed only because they scare people, not because they are actually dangerous to humans.
All spiders have some amount of venom with varying degrees of potency.
The fangs of a spider are hollow. The venom will rapidly paralyze the victim and aid in digestion. Fortunately, most spiders are not dangerous to humans because their fangs are either too short or too fragile to penetrate human skin. Spiders do not attack in herds. Spiders do not lay in wait and attack people.
