The Arachnid class is an example of an arthropod group characterized by possessing two main body segments, eight legs, but having no antennae. All arthropods except chelicerates and proturans have antennae. (The chelicerates include arachnids, horseshoe crabs, and sea spiders.)
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.
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 (crabs, Pycnogonida, and Mercostonata) are arthropods that lack jaws.
