chelicera

The species name is derived from the status of the teeth of the chelicera.

Unlike females the male bears a pair of flagella, one on each chelicera.

This type of chelicera occurs exclusively in the Tetrapulmonata.

This kind of chelicera is rotated and occurs exclusively in the Araneomorphae spiders.

Unlike other mygalomorph spiders, the Ctenizidae have a rastellum on the chelicera.

Jackknife chelicera presents two different forms: orthognathous and labidognathous.

Males in all families but Eremobatidae possess a flagellum on the basal article of the chelicera.

In most species, only the female spider is capable of effectively delivering the venom to humans as the males have much smaller chelicera.

Only spiders of fairly large species possess chelicera long enough to penetrate human skin, and most of those are females.

The male lacks the characteristic process of the chelicera found in most other males of the genus Padilla.

In the accompanying photograph of a male Solifugid, one flagellum is just visible near the tip of each chelicera.

The jackknife chelicera is subchelate (with fixed finger much reduced or absent) and is composed of two segments.

The pilus dentilis, a sensory organ on the chelicera, is serrate, which distinguishes it from A. gymnuromys.

As in other solifuges, mating involves the male depositing a spermatogonia that is manipulated into the female genital opening using their chelicera.

However, the male pedipalp, chelicera and cephalothorax drawn by Proszynski (1984), and recently collected specimens indicate otherwise.

On the underside of the prosoma there are six paired appendages, the first of which (the chelicera) are used to pass food into the mouth.

The chelicerae of males are greatly enlarged and obliquely oriented, with each chelicera having a prominent inner tooth and a long, curved fang.

The scissor chelicera is chelate and composed of two segments and occurs in the orders Pseudoscorpiones and Solifugae.

Most males in this genus have a characteristic very long, forward projecting process on each chelicera, which looks like a lance which has been bent near the tip.

Typically they have yellowish bodies with a contrasting blackish color on chelicera, the fingers of the pedipalps, the fifth segment of the tail, and the cephalothorax.

A gigantic new carapaceon/neopteron that resembles a spider, called Nerusukyura, nicknamed "Shadow Spider", and is classified as a "Chelicera", an arachnid like class.

This kind of chelicera occurs in the Liphistiomorphae and Mygalomorphae spiders and in the related orders Amblypygi, Schizomida, Thelyphonida.

In all species, the digitus mobilis of the chelicera is reduced to small rests, and the distal pedipalp article is connected to a more or less complex membranous structure.

This hypothesis was based on the supposed presence of unique spider features such as silk-producing spinnerets and the opening of a venom gland on the fang of the chelicera.

In this case, the high levels of serotonin contained in the venom, plus at minimum strong chelicera, will contribute to deliver a very painful bite that can result in muscle shock.
