They have different mouth parts used for feeding. Mandibulates have mandibles, or opposing mouthparts which are like jaws. Cherlicerates have pincer-like mouthparts (cherlicera).

What is the Biggest group of 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.
What structures of chelicerates are analogous to the antennae of chilopods and other mandibulates?
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.
Do chelicerates have wings?
no chelicerates are mostly spiders or scorpions or horseshoe crabs
What makes a tarantula an arthropod?
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.
