First, daddy longlegs make up the order Opiliones and aren't spiders. They are arachnids, but so too are mites, ticks, and scorpions. Omnivorous daddy longlegs have pill-shaped bodies. They consume plants, fungi, carrion, and invertebrates, including other arthropods and snails. Unlike spiders, they can't make silk for spinning webs. Spiders have t...
A common urban myth is that daddy longlegs have the most toxic venom of all spiders, but their fangs are too small to bite. Even if they were spiders, they don't have venom glands or fangs. An episode of the television show "MythBusters"debunked the daddy longlegs myth with a bite experiment. Unfortunately, they didn't explain that those were cella...
Daddy longlegs have simple eyes mounted on eye turrets attached to their bodies. These eyes act as light sensors and do not appear to provide more than blurry images. Research shows that cave harvestmen are most receptive to the light emitted by the glowworms that make up their diet.Harvestmen learn about the world around them using the sensitive t...
The Opiliones first appeared a long time ago and have barely changed at all over millions of years. Fossils dating back 400 million years, before dinosaurs roamed the earth, look very similar to today's daddy longlegs. Because of their extensive history, researchers use daddy longlegs fossils for evolutionary and biogeographic studies. Scientists e...
Another myth is that their legs grow back. During the average lifetime, daddy longlegs have a 60 percent chanceof losing one or more legs. This can happen when a predator pulls them off or when the harvestman chooses to detach the appendage. Their gait then permanently changes. Typically, they use the two longest legs as feelers, then alternate the...
Detaching their legs isn't the only or even primary way they escape predators. Daddy longlegs prefer to blend in with their surroundings and play dead. Warning predators away with a foul-smelling liquid from their exocrine glands is another defense. The glands are unique to these arachnids and are also used to communicate with other harvestmen. Som...
Daddy longlegs have small, hairy appendages near their mouth used as sensory organs called pedipalps. Using high-speed cameras, researchers discovered the hairs on the pedipalps secrete a glue-like substance to capture prey.They embrace their mark with their pedipalps and apply the secretion in milliseconds. With only a few microscopic drops, the g...
Groups of daddy longlegs sometimes form thick clusters called aggregations. Aggregations contain three or more huntsmen, with one enormous assemblage containing 300,000 individuals. Once created, the mass can stay in place for months, particularly during winter. Researchers speculate that aggregations form for mating, temperature control, humidity ...
Of the thousands of Opiliones, six are listed as critically endangered and possibly extinct, eight are endangered, and two more are vulnerable. The threats affecting the animals are primarily habitat destruction and degradation. Several species are threatened by the Ceylon cinnamon cultivation taking place in Seychelles. These invasive trees make t...
