In some cases the male pedipalps
and female epigynes were dissected for more detailed study.
foili from Utterbackia imbecillis indicated that these mites would occasionally penetrate the gills of their host using their pedipalps
The genus is characterized by having: relatively large body (more than 5 mm long); a crown-like mound containing numerous black-tipped tubercles on cephalothorax anterior to the ocularium, coxae I-IV smooth and only with sparse setae; chelicerae usually normal structured with blackish brown zebra-like stripped pattern, pedipalps
short, robust and femora, patella, tibiae covered with numerous black-tipped tubercles (males having microtubercles on ventor of tarsus); legs short or more commonly long (Tsurusaki 1987; Tsurusaki et al.

Solifugids were omitted from this analysis because they easily escape pitfall traps using the suctorial organs on their pedipalps
(Cushing et al.
While on the female's ventral side, the male drummed with his pedipalps
on and near the female's genital openings (epigynum), and finally inserted a pedipalp
into the female genital opening.
Male horseshoe crabs without modified pedipalps
(claspers) were considered immature and those with modified pedipalps
were considered mature (Hata and Berkson, 2004).
Scorpions can be easily identified by their long sting-bearing tail and a pair of pincers on long arms, known as pedipalps
, at the front of the body.
Notably, the black pedipalps
of the tufted male have very low reflectance intensities compared to the grey morph and the pedipalps
of the grey morph peak in the orange wavelengths.
Amblypygids have no venom glands; instead, they use their sharp raptoral pedipalps
(first pair of appendages) to capture prey.
The male yellow garden spider, Argiope aurantia, has been shown to collaborate in his own instantaneous death: he dies by his own "decision" after inserting the second of his two pedipalps
(mating appendages) inside one of the female's genital apertures.
As is typical in spiders, a male of Tidarren sisyphoides develops two protrusions with hollow tips, or pedipalps
, on the front of his body for delivering sperm, explains Duncan J.
