All spiders belong to the class arachnida, have eight legs and two body sections: the cephalothorax and abdomen. The cephalothorax is a combination of head and thorax found in insects.  Palps (sensory organs) and fangs are at the front of the body.
Spiders are usually associated with webs, but not all spiders, such as the huntsman create webs. 

There many different species some are venomous and therefore may be harmful to human beings such as the redback and others although they look menacing such as the huntsman cause no harm.  Huntsman are actually very good predators of small insects in the home.
