Knowra Pseudoscorpion Pseudoscorpion A small arachnid in the order Pseudoscorpiones, with pincers resembling a scorpion’s but no tail or venomous stinger. Many species produce silk from glands in their jaws.
Arachnid : An arthropod with four pairs of walking legs and no antennae. Pseudoscorpions belong to this group, alongside spiders, scorpions, and mites.
Venom : A biological secretion delivered by an animal to impair or kill another organism. Some pseudoscorpions inject venom into prey through glands in their pincers.
Mites : Small arachnids in the subclass Acari, occupying habitats from soil to animal hosts. Mites are among the minute arthropods that pseudoscorpions hunt.
Whip scorpion : An arachnid in the order Thelyphonida, with large pincers and a long, whip-like tail filament. Whip scorpions have a tail filament, unlike the tailless pseudoscorpion.
Pseudoscorpiones : The arachnid order containing all pseudoscorpions. This is the taxonomic order that defines the animal described on this page.
Predation : An ecological interaction in which one organism captures and consumes another. Pseudoscorpions are small predators that seize arthropods with their pedipalps.
Springtail : A small, wingless hexapod common in soil and leaf litter. Springtails are frequent prey in the litter habitats where pseudoscorpions forage.
Harvestman : An arachnid in the order Opiliones, often recognized by long legs and a compact body. Harvestmen may look similarly small but lack the conspicuous pincer-tipped pedipalps.
Chelicera : A pair of front appendages in chelicerates, used for feeding or handling prey. Pseudoscorpions use their small chelicerae to manipulate food and produce silk.
Silk : A protein fiber spun by various animals for structures, prey capture, or protection. Pseudoscorpions make silk from their chelicerae to build protective retreats.
