Spiders and Harvestmen
Arachnids differ from insects in that they all have four pairs of legs and no antennea. Although they all have two body segments these are only obvious in spiders; harvestmen appear to have only a single segment. Britain does not have any spiders that are poisonous to man, although a few can give a small bite and may cause an allergic reation in some people.
