Something Dr. Ronald Ochoa at USDA once told me stuck with me: mites aren’t arachnids. I didn’t appreciate how true that was. Because they’re tiny, we didn’t see them as a miniaturized slice of chelicerate diversity. Great read by Dr. Sam Bolton.

Mites Are a Made-Up Taxon: New Analysis Further Debunks Long-Held Classification
What scientists know as "mites" is almost certainly an artificial taxonomic group, according to recent phylogenetic analyses and studies using advanced microscopic techniques.

The chelicerae are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or as a type of pincers.

Chelicerae are such a cool adaptation, and now we know they arose in the Cambrian.
