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 ...
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 ...
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".
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 ...
They are small arachnids with a flat, pear-shaped body, and pincer-like pedipalps that resemble those of scorpions. They usually range from 2 to 8 mm (0.08 to 0.31 in) in length. [3] The largest known species is Garypus titanius of Ascension Island [4] at up to 12 mm (0.5 in). [5] [6] Range is generally smaller at an average of 3 mm (0.1 in). [2]
The front pair of legs are modified for use as antennae-like feelers, with many fine segments giving the appearance of a "whip". When a suitable prey is located with the antenniform legs, the amblypygid seizes its victim with large spines on the grasping pedipalps, impaling and immobilizing the prey. This is typically done while climbing the ...
In most insect legs, including the posterior four legs of a mantis, the coxa and trochanter combine as an inconspicuous base of the leg; in the raptorial legs, however, the coxa and trochanter combine to form a segment about as long as the femur, which is a spiky part of the grasping apparatus (see illustration). Located at the base of the ...
Centipedes, in addition to their mouthparts, possess a pair of "poison claws", or forcipules. These, like the maxillipeds of crustaceans, are modified legs and not true mouthparts. [2] The forcipules arise from the first body segment, curving forward and to the midline. The tip is a pointed fang, which has an opening from a venom gland.
