Verified step by step guidance1
Begin by understanding the classification of Chelicerata. Chelicerata is a subphylum within the phylum Arthropoda, which includes organisms like spiders, scorpions, and horseshoe crabs.
Identify the key characteristics of Chelicerata. Unlike other arthropods, members of Chelicerata do not have wings or antennae. Instead, they possess chelicerae, which are specialized mouthparts used for feeding.
Recognize that Chelicerata typically have four pairs of legs, not three. This distinguishes them from insects, which have three pairs of legs.
Understand the function of chelicerae. These are often used for grasping and piercing prey, and are a defining feature of the Chelicerata class.
Conclude that the possession of chelicerae is the correct characteristic of the class Chelicerata, differentiating them from other arthropods that may have wings or antennae.
