Opiliones
The Opiliones (formerly Phalangida) are an order of arachnids,
colloquially known as harvestmen, harvesters, daddy long legs, or granddaddy long legs. Over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014.
