Harvestman (family Epedanidae) on a branch. Harvestmen (order Opiliones) are arachnids but are distinct from spiders in that they have only one body section as opposed to two. They are omnivorous and eat a wide range of foods including dead matter, fruit and small insects. They secrete a foul smelling liquid as a defence mechanism.
