Harvestman The Biology Of Opiliones Pronunciation
Arachnids are a class (Arachnida) of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. All arachnids have eight. Members of the arachnid order Opiliones, or harvestmen, are among the most visible terrestrial arthropods, but even most arachnologists cannot reliably assign a species name to a specimen. Like many other invertebrates, the ecological signifi-cance of harvestmen is largely unknown, and remarkably little research has been.
Opiliones (more commonly known as Harvestmen) are an Order of eight-legged invertebrates within the Class Arachnida. Opiliones have long thin walking legs and their bodies have the appearance of being just a single structure. They do possess both cephalothorax and abdomen but these are joined together with no narrowing between the two body segments.
There are over 6,000 known species of harvestmen and most are omnivorous. They do not possess fangs or venom and catch prey using their chelicerae.
