The Oral Apparatus of the Cross Spider

The oral apparatus of a spider, specifically the cross spider (Araneus diadematus), refers to the structures involved in feeding and capturing prey. The cross spider belongs to the class Arachnida and the order Araneae. The oral apparatus of spiders consists of several specialized structures, including the chelicerae, fangs, and the labium.

Chelicerae: The chelicerae are the primary feeding appendages of spiders. They are located at the front of the cephalothorax (head and thorax combined) and are used to grasp and immobilize prey. The chelicerae of the cross spider are equipped with fangs that inject venom into the prey to subdue it [[3]](https://ru.wikipedia.org/wiki/%D0%A5%D0%B5%D0%BB%D0%B8%D1%86%D0%B5%D1%80%D1%8B).

Fangs: The fangs are the sharp, pointed structures located at the tips of the chelicerae. They are used to pierce the exoskeleton of the prey and inject venom. The venom helps to immobilize and digest the prey before it is consumed.

Labium: The labium is a structure located on the ventral side of the cephalothorax, below the chelicerae. It acts as a protective cover for the mouthparts and assists in manipulating and processing food during feeding [[3]](https://ru.wikipedia.org/wiki/%D0%A5%D0%B5%D0%BB%D0%B8%D1%86%D0%B5%D1%80%D1%8B).

The oral apparatus of spiders, including the cross spider, is adapted for capturing and feeding on a variety of prey. The chelicerae and fangs are specialized for grasping and immobilizing prey, while the labium helps in the manipulation and processing of food.
