Opiliones
(Redirected from Harvestmen)
Opiliones are an order of arachnids colloquially known as harvestmen, harvesters or daddy longlegs. Although they belong to the class of Arachnida, they are not spiders, which are of the order Araneae.
Description[edit | edit source]
Opiliones are known for their exceptionally long legs, compared to their body size. However, there are also short-legged species. The body of an Opiliones is divided into two tagmata: the anterior cephalothorax or prosoma, and the posterior 10-segmented abdomen or opisthosoma.
Distribution and habitat[edit | edit source]
Opiliones are virtually cosmopolitan, found in diverse habitats ranging from the Arctic, to tropical rainforest, to desert. They are most common in moist environments.
Behavior and ecology[edit | edit source]
Opiliones are omnivorous, eating small arthropods, worms, and snails, as well as plant material. They do not have venom glands and pose no danger to humans.
Taxonomy[edit | edit source]
The order Opiliones is divided into four suborders: Cyphophthalmi, Eupnoi, Dyspnoi, and Laniatores. These are further divided into families and genera.
