Harvestmen are an order of arachnids( spiders), with which they share many characteristics: their body is divided into two body regions (tagmata), the abdomen (opisthosoma) and the cephalothorax (prosoma); however, unlike in spiders, the juncture is often poorly defined. They have chelicerae, pedipalps and four pairs of legs. Most harvestmen have two eyes, although there are eyeless species. Unlike spiders, harvestmen do not have venom or silk glands. For more anatomy details visit en.wikipedia.org/wiki/Harvestman_anatomy

The harvestman in the first five photos is a native to New Zealand. There a many native species and few are named.This photos is of a male Long-clawed harvestman (Megalopsalis sp),  which have black bodies and enlarged, two-segmented chelicerae (mouth appendages) that tower above their body like a crane. It has very fine legs which break off easily to help it escape from a predator. With such long legs it can move very quickly over a range of terrains.
