You probably know this already, but the arachnids also contain mites, harvestmen, uropygids, amblypygids and solifugae. I imagine Catfish only named arachnids in the arthropod category because scorpions and tarantulas are the most popular bug pets (personally, I'm more of a centipede person, but I like scorpions and spiders very much as well).
