Which are arachnids?

• A. Fleas
• B. Mites and ticks
• C. Maggots
• D. Fleas and ticks

Answer: (C)

Arachnids are jointed-foot arthropods that typically have eight legs and two main body segments, and they include mites, ticks, spiders, and scorpions. Insects, on the other hand, have six legs and three body parts, with many species having wings; their larvae are not arachnids. Mites and ticks fit the arachnid category, since they are eight-legged and belong to the same large group as spiders. Maggots are the larvae of flies, which are insects, so they are not arachnids. Fleas are also insects. Therefore, the organisms that are arachnids are mites and ticks.
