Spiders are useful in pest and insect control, their venom can be used in medicine or pesticides, and the spider silk werbbing can be used to make cloth. Yet they are one of the most commonly feared types of animal in the world. According to statistics, about 50% of women, and 10% of men, are scared of spiders. This may be an instinctual fear, as only a few species are actually harmful to humans and are unlikely to bite unless provoked and trapped. Spiders are beautiful too, they come in an array of colours and shapes.
