Which following is an example of an arachnid?

• A. Beetles
• B. Spiders
• C. Crabs
• D. Lobsters

Answer: (B)

Understanding what defines an arachnid helps distinguish them from other arthropods. Arachnids typically have eight legs, a body divided into two main parts (a cephalothorax and abdomen), and no antennae. This combination of traits is characteristic of the group that includes spiders, scorpions, mites, and ticks. Spiders fit perfectly: they have eight legs, lack antennae, and their body is arranged into two main sections. Beetles, on the other hand, are insects with six legs, three body segments, and usually wings. Crabs and lobsters are crustaceans with multiple legs and two pairs of antennae, among other differences from arachnids. So, spiders are the clear example of an arachnid.
