Harvestman

Harvestmen (order Opiliones) are members of the class Arachnida, together with spiders, scorpions, pseudoscorpions, ticks and mites. Like all arachnids, harvestmen have four pairs of walking legs, a pair of chelicerae, and a pair of small, leg-like appendages called pedipalps. The body of most species is only 3-7 mm long, but the animals often appear larger due to their long legs (in one group of harvestmen the legs are exceptionally long - up to 20 times the length of the body). The second pair of legs is often the longest, having a tactile sensory function. Two simple eyes usually sit close together on top of a small tubercle in the middle of the carapace. In some primitive mite-like harvestmen the eyes are absent.
