I found this spider in my garden which is near Derby. The longest legs are about 2 inches long, but the body is tiny in comparison. It is like nothing I have seen before, certainly not in the UK, so it would be great to know what it is (and how far I should run!!!). The original photo is also attached which is of sufficient quality to zoom in for closer analysis.
It's a harvestman or harvestspider, an arachnid but not a true spider. I can't ID them to species but you've nothing to worry about. There are several native species and they're omnivores, but don't bite humans. Note that the second pair of legs is the longest. These legs have lots of sensory organs and uses them to taste its food, feel the way ahead etc.
