Forcipules go by a variety of names in both scientific and colloquial usages. They are sometimes known as poison claws or jaw legs , [ 4 ] referencing their evolution from maxillipeds, a term which they are also sometimes known by in the context of centipedes ( maxillipeds, maxillipedes ).
Each of the second maxillae ends in a pointed claw. The forcipular coxosternite features a pair of chitin lines that reach the condyles at the anterior margin at the base of the forcipules. This anterior margin is angulated rather than nearly straight. The forcipules and the corresponding sternum each lack teeth. Each forcipule features only ...
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 ...
For example, in both of these groups, the labrum lacks a distinct separation between the middle and lateral parts, the second maxillae lack claws and are reduced in size relative to the first maxillae, and the two articles before the ultimate article of the forcipules each feature a denticle with setae near the apex as well as at the base ...
Stenotaenia is a is a genus of soil centipedes in the family Geophildae. [1] [2] This genus has a western Palearctic distribution.The centipedes in this genus are notable for exhibiting exceptional diversity in not only segment number, ranging from 43 to 115 leg-bearing segments, but also body size, ranging between 1 cm and 8 cm in length.
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.
"Even if it had some centipede mouthparts, its trunk anatomy seems to indicate that it was not carnivorous like modern centipedes, as it did not have forcipules - centipede 'fangs' - or any ...
Underside of Scolopendra cingulata, showing the forcipules. A centipede bite is an injury resulting from the action of a centipede's forcipules, stinger-like appendages that pierce the skin and inject venom into the wound. Such a wound is not strictly speaking a bite, as the forcipules are a modified first pair of legs rather than true mouthparts.
