Matthiesen (1979) identified this deformity in the scorpion Tityus cambridgei (Pocock): the affected individual had a double prosoma, two sets of eyes and four pedipalps
The whole body of this scorpion is yellowish and only its hands (end of pedipalp
segment) are dark brown.
as in Figs 13-15, with a characteristic tooth-like process on retrolateral edge of cymbium at base.
It differs from Phalangium in terms of shorter tarsus of pedipalps
, shorter and thicker legs (Banks, 1893; Snegovaya 2012).
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.
In addition to the mouthparts, the capitulum contain chelicera (appendages on each side of the mouth) that pierce, tear, or grasp host tissues and protect the hypostome; pedipalps
(a pair of jointed appendages) that aid feeding; a hypostome (ventral fusion of the pedipalps
) that helps anchor the tick to the host; and a rostrum that extends dorsally over the mouth.
Once the prey has been captured and subdued, it is transferred to the mouth parts by the pedipalps
, large claws that resemble those of a lobster.
Spiders have a pair of jointed appendages (called pedipalps
or palps) on either side of the chelicerae that look like short legs.
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.
