Are daddy long legs spiders or non-spiders? Both harvestmen (Opiliones) and cellar spiders are known as daddy long legs. But both are not related, and neither are there links between the two groups of species. Related to the class of arachnids, both species belong to different orders and families. The spider, daddy long legs (Pholcus phalangioides), also known as skull spiders and cellar spiders, has eight uniquely long legs, six eyes, and a peanut-shaped body. They make great predators having fangs ejecting venomous secretions from their glands and slyly attacking their prey with their fangs. To search for and capture their prey, they create thin silky webs. Preferring isolation as their site of stay, they maintain no links with fellow daddy long legs. In times of mating, they become very sociable and search for mates, and lay 20-30 eggs. The independent offspring cut all ties with their parents once they become efficient in searching for food.  Interestingly, these spiders are venomous for their prey but are not toxic to humans.
