Spiders, scorpions, mites, and ticks are examples of which arthropod group?

• A. Arachnid
• B. Insect
• C. Crustacean
• D. Myriapod

Answer: (A)

Spiders, scorpions, mites, and ticks are arachnids. The defining traits you’ll notice in this group are eight legs and two main body sections, plus they lack antennae. They also have chelicerae and pedipalps as mouthparts. These features distinguish them from insects, which have six legs, three body segments, and usually antennae (and sometimes wings); from crustaceans, which typically have two pairs of antennae and gills and many live in water; and from myriapods like centipedes and millipedes, which have numerous legs and many body segments.
