They have different mouth parts used for feeding. Mandibulates have mandibles, or opposing mouthparts which are like jaws. Cherlicerates have pincer-like mouthparts (cherlicera).
A chelicerate does not have antennae because it is missing the nerve bundle that would control that structure. Instead, chelicerates use setae to detect changes in air currents and provide equivalents to smell and taste.
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.

Chelicerates are a subphylum of arthropods that include creatures such as spiders and scorpions. They are characterized by the presence of chelicerae, which are specialized mouthparts used for feeding. Other notable features include their segmented bodies, typically divided into two main parts: the cephalothorax and abdomen, and the absence of antennae. Other examples of chelicerates include horseshoe crabs and ticks.
