The first, or anterior, of the five pairs of leg-like appendages are not "actual" legs, but pedipalps, and they have only five segments each. The pedipalps of the Solifugae function partly as sense organs similar to insects' antennae, and partly in locomotion, feeding, and fighting. In normal locomotion, they do not quite touch the ground, but ...
Mycteroptidae are a family of eurypterids, a group of extinct chelicerate arthropods commonly known as "sea scorpions". The family is one of three families contained in the superfamily Mycteropoidea (along with Hibbertopteridae and Drepanopteridae), which in turn is one of four superfamilies classified as part of the suborder Stylonurina.
The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons (pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. [1] Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in ...

[1] [2] Generally, solifuges have 5 pairs of malleoli on the ventral surface of the fourth pair of legs. malleoli are usually larger in males. [3] A malleolus comprises a basal stalk and a triangular fan, with epicuticular protrusions on each anterior face, and granular structures on each stalk, with undulate surfaces at each distal end.
In Solifugae, the palps are quite leg-like, so that these animals appear to have ten legs. The larvae of mites and Ricinulei have only six legs; a fourth pair usually appears when they moult into nymphs. However, mites are variable: as well as eight, there are adult mites with six or, like in Eriophyoidea, even four legs.
Boreosolifugae is a suborder of animals in the order Solifugae.In 2023, the internal phylogeny of solifuges was resolved for the first time using phylogenomics. [1] The molecular phylogeny of the order showed evidence for two groups of families, which were recognized as suborders.
These appendages were generally walking legs that were cylindrical in shape and were covered in spines in some species. In most lineages, the limbs tended to get larger the farther back they were. In the Eurypterina suborder , the larger of the two eurypterid suborders, the sixth pair of appendages was also modified into a swimming paddle to ...
