Harvestman Arachnid...

Harvestmen are not spiders even though they look like them. They are an 'Opilone' which is a group of arachnids which are related to spiders. They don't spin a web or make venom or have fangs. Their defence is to release a nasty smelling substance and a fact I like is this - they can get rid of a leg should they find themselves caught!
