Parahya submersa is a species of pseudoscorpion that resides within the monotypic family Parahyidae. It occurs in Singapore and the Caroline Islands.
Garypus titanius, the giant pseudoscorpion, is the largest species of pseudoscorpion—small, scorpion-looking creatures—in the world. Critically endangered, it is restricted to Boatswain Bird Island, a small rocky island off Ascension Island in the South Atlantic Ocean. Pseudoscorpions are venomous arachnids and are generally tiny—around 3 mm long. The giant pseudoscorpion, though, can grow to five times that size at 11 mm. It lives among seabird colonies, feeding mainly at night on smaller prey such as insects. It belongs to the Garypidae family.

The Tooth Cave pseudoscorpion(Tartarocreagris texana) is a small cave-dwelling arachnid of the family Neobisiidae. The species was originally assigned to the genus Microcreagris, and then reassigned to Austalillocregris before arriving at its current genus, Tartarocreagris. The Tooth Cave pseudoscorpion has a small geographic distribution, known to occur in only two caves in Travis County, Texas. Additionally, it is tentatively identified in two nearby caves in Texas, but more research is necessary to accurately define the range where the species lives. There is little known about the biology, life cycle, and life history of the Tooth Cave pseudoscorpion due to a lack of research and study. Because of this, the Tooth Cave pseudoscorpion is listed on the IUCN Red List as data deficient. Under the Endangered Species Act, the Tooth Cave pseudoscorpion is listed as endangered. Recovery plans for the species focus mostly on preserving the karst ecosystem that the pseudoscorpions live in, especially including lessening human impacts on the environment.
