Opiliones – Harvesters, daddy longlegs & allies
They lack silk glands and do not build webs
Harvestmen, often recognized by their tiny bodies and exceptionally long, delicate legs, possess unique and intriguing characteristics distinguishing them from other arachnids. Harvestmen exhibit a single fused body segment, unlike their spider relatives, where the abdomen and cephalothorax become one. This feature contributes to their distinct appearance, with their long, thin legs lending them an unmistakable silhouette.
These remarkable arachnids are primarily opportunistic feeders, displaying a versatile diet that includes small invertebrates, insects, and even tiny spiders. Additionally, they play a vital role as nature’s recyclers, participating in scavenging by consuming decaying plant and animal matter. This ability to utilize decaying organic material aids in nutrient cycling within ecosystems, making them valuable contributors to ecological processes.
When faced with threats, harvestmen employ an array of defense mechanisms. Some species release defensive secretions that deter potential predators, serving as a chemical defense strategy. Others resort to dramatic tactics, such as faking death or utilizing their extraordinarily long legs to make quick escapes. Many of these species also exhibit cryptic coloration, allowing them to blend seamlessly into their surroundings and evade detection by predators. This camouflage and their capacity to remain motionless for extended periods enhances their survival in various environments and protects them from potential threats.
