In chelicerates, the chelicerae (mouthpart) are analogous to the antennae of chilopods and other mandibulates. Chelicerae are a pair of appendages located near the mouth used for feeding and defense. They are sensory and help in manipulating food, similar to how antennae function in other arthropods.
Chelicerates are a group of arthropods that lack jaws. Examples of chelicerates include horseshoe crabs, mites, ticks, spiders, and scorpions. Arthropods that have jaws are classified as mandibulates.
no chelicerates are mostly spiders or scorpions or horseshoe crabs
Tarantulas and other spiders are classified as arthropods by virtue of their physical characteristics. In taxonomic classification arthropods branch into two major subcategories, the chelicerates which include arachnids, and the mandibulates which includes the myriapods, crustaceans and insects. These all share the broad definition of arthropoda which is characterized by joint appendages and possession of an exoskeleton.
No
Yes, wings are found in insects, but not in chelicerates such as spiders and scorpions. Chelicerates have evolved a different body plan that does not include wings for flight.

Chelicerae are specialized feeding appendages found in chelicerates, a subphylum of arthropods that includes spiders, scorpions, and horseshoe crabs. They are used for grasping and tearing food. Other arthropods, such as insects and crustaceans, have different types of mouthparts for feeding, like mandibles or maxillae.
