Ok, these spiders are not spiders…

Opiliones (from Wikipedia): …Although they belong to the class of arachnids, harvestmen are not spiders…

These arachnids are known for their exceptionally long walking legs, compared to body size, although there are also short-legged species. The difference between harvestmen and spiders is that in harvestmen the two main body sections (the abdomen with ten segments and cephalothorax, or prosoma and opisthosoma) are broadly joined, so that they appear to be one oval structure; they also have no venom or silk glands.

Harvestmen are very old arachnids. Fossils from the Devonian Rhynie chert, 410 million years ago, already show characteristics like tracheae and sexual organs, proving that the group has lived on land since that time.
