Spider Photos - Pseudoscorpion

Pseudoscorpions or "Book scorpions" are about 4mm long, flat-bodied arachnids with a short, usually oval abdomen. They have a pair of large pincer like claws (pedipalps) that project forward from the front of the body. There is no curved upward stinger from the rear tip of the abdomen as found in true scorpions. The body colour ranges from yellowish-tan to dark-brown, with the paired claws sometimes black. Some have 2 or 4 eyes while others have none. Legs are 5-segmented. Many thanks for allowing us to use the photos sent in. All photos are copyright to their owners and may not be reproduced without permission. Please choose a section:

PSEUDOSCORPIONS

Pseudoscorpions are small arachnids with a flat, pear-shaped body and pincers that resemble those of scorpions. They usually range from 2 to 8 millimetres (0.079 to 0.31 in) in length. The largest known species is Garypus titanius of Ascension Island at up to 12 mm.

The abdomen, known as the opisthosoma, is made up of twelve segments, each protected by plates (called tergites above and sternites below) made of chitin. The abdomen is short and rounded at the rear, rather than extending into a segmented tail and stinger like true scorpions (the fact that they look exactly like scorpions, aside from not having a stinger tail, is the source of the name "Pseudoscorpion"). The color of the body can be yellowish-tan to dark-brown, with the paired claws often a contrastiA pseudoscorpion has eight legs with five to seven segments; the number of fused segments is used to distinguish families and genera. They have two very long ng color. They may have two, four or no eyes.

A pseudoscorpion has eight legs with five to seven segments; the number of fused segments is used to distinguish families and genera. They have two very long palpal chelae (pedipalps or pincers) which strongly resemble the pincers found on a scorpion.

The pedipalps generally consist of an immobile "hand" and "finger", with a separate movable finger controlled by an adductor muscle. A venom gland and duct are usually located in the mobile finger; the poison is used to capture and immobilize the pseudoscorpion's prey. During digestion, pseudoscorpions pour a mildly corrosive fluid over the prey, then ingest the liquefied remains.

Pseudoscorpions spin silk from a gland in their jaws to make disk-shaped cocoons for mating, molting, or waiting out cold weather. Another trait they share with their closest relatives, the spiders, is breathing through spiracles. However, they do not have book lungs as most spiders do.

Hi, I recently grabed a nice macro of what I believe is a crab spider, but am looking for some conformation. It was interesting to watch as he moved in all directions. He was about 2 maybe 3mm in legnth, such a tiny thing. I found him crawling on one of my walls in the house. At first I thought he was a tic, until I noticed the 8 legs after looking over the photos closer. Any idea's? Thanks Steve Yezek Grafton Iowa
