This video says about itself:
Unlike spiders, which have two main body sections, Harvestmen only have one. This one’s body is about 1/4 inch long. Harvestmen have eight legs like a spider. The Harvestman also has a little knob on its head with two eyes. They don’t possess silk glands, produce no webs, are non-venomous. They’re generally carnivorous, feeding on live invertebrate prey. Some species prefer to dine on dead animals or juices from plants, fruits and veggies.
Harvestmen release a foul-smelling odor as a defense against predators.

In the Onderste Bos nature reserve in the south of Limburg province under a piece of wood the very rare harvestman Paranemastoma quadripunctatum has been found. This animal was in the forest edge in a nature reserve of ARK Natuurontwikkeling.
