Minuca pugnax, like other members of the family Ocypodidae, have chelae of different sizes: a large left chela and a small right chela. A chela (/ ˈ k iː l ə /) – also called a claw, nipper, or pincer – is a pincer-shaped organ at the end of certain limbs of some arthropods. [1] The name comes from Ancient Greek χηλή, through Neo ...
All centipedes are venomous and can inflict painful stings, injecting their venom through pincer-like appendages known as forcipules or toxicognaths, which are actually modified legs instead of fangs. Despite the name, no species of centipede has exactly 100 legs; the number of pairs of legs is an odd number that ranges from 15 pairs to 191 pairs.
They were initially leg-like, then progressed into a more pincer or claw-like shape, as seen today, and restricted to horizontal movement. [1] The forcipules of modern Scutigeromorphs are the most significantly different in shape: they are more leg-like, and cannot hold prey like they are used among other orders: they are used for envenomation ...
Scorpion pose in yoga has one or both legs pointing forward over the head, like a scorpion's tail. [137] Since classical times, the scorpion with its powerful stinger has been used to provide a name for weapons. In the Roman army, the scorpio was a torsion siege engine used to shoot a projectile.

The pedipalps generally consist of an immobile "hand" and mobile "finger", the latter controlled by an adductor muscle. Members of the clade Iocheirata, which contains the majority of pseudoscorpions, are venomous , with a venom gland and duct usually located in the mobile finger; the venom is used to immobilize the pseudoscorpion's prey.
Earwigs make up the insect order Dermaptera.With about 2,000 species [1] in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short, rarely used forewings, hence the scientific order name, "skin wings".
As with many other arthropods, the larvae look like miniature versions of the adult, albeit with fewer legs. Young centipedes have four pairs of legs when they are hatched. They gain a new pair with the first molting, and two pairs with each of their five subsequent moltings. Adults with 15 pairs of legs retain that number through three more ...
Australian water scorpions have six legs; the front two forelegs are pincer-like used for grasping aquatic prey and the hind legs are used for moving about. [3] They have a relatively short, pointed head and small eyes. [2] They have antennae with 3 segments and a finder-like projection, hidden in a groove beneath the eyes. [2]
