Detailed explanation-1: -Spiders’ chelicerae, which are fang-shaped, are related to basal venom glands. These fangs have an internal duct that finish in a terminal opening through which venom is released and injected inside victims’ bodies like a hypodermic needle. Spiders have the most evolved form of chelicerae: jackknife chelicerae.

Detailed explanation-2: -Chelicerates have two body segments; a cephalothorax and an abdomen. They have no antennae, but have six pairs of appendages. The most anterior appendages are called the chelicerae and are normally modified into pincers or fangs. The following pair, the pedipalps, are also commonly modified.

Detailed explanation-3: -The chelicerae are a spider’s jaws. They are located on the very front of a spider’s cephalothorax. Every Kentucky spider has a pair of chelicerae, and they are tipped with fangs. Chelicerae are filled with muscles, and are used to hold prey while the spider injects venom.

Detailed explanation-4: -Instead of mandibles capable of chewing, spiders have fang-tipped jaws called chelicerae. With these, they pierce their prey and inject a venomous fluid that immobilizes it.

Detailed explanation-5: -Chelicerae are jointed appendages near the mouth of some arthropods (spiders, scorpions, crustacea). These arthropods are known as the Chelicerata.
