CLASS- INSECTA (Phylum- Arthropoda)
-Arthropods are a HUGE group of creatures, and contain both the Lobsters & Crabs, and the Insects & Arachnids. Yup, every time you eat a lobster, you're eating a giant Sea Bug. Insects are by FAR the largest group of animals in the world, containing nearly 90% of ALL different species on the planet. Hugely diverse, they are nonetheless linked by various factors. They all have three pairs of legs, a three-segmented body (the origination of their name is Latin for "cut into sections") containing a head, thorax and abdomen, a pair of antennae, and an exoskeleton (ie. they lack true bone matter). Most are winged and can fly, but others (the Ants, actually related to the Wasps) don't- only the male Ants in a colony ever develop wings. Some are good at stealth (Stick Insects), others are hunters (Mantids, Dragonflies), some are team players (Ants & the Bee/Wasp/Hornet group), and others are solitary (some Beetles). Some are pretty (Butterflies) and others are hideously awesome (Stag Beetles). They're pests the world-over (especially Fleas, Mosquitos & Cockroaches), and have proven how awesome they are by virtue of the fact that while everything else walking goes extinct easily, they will always be around, and likely surpass even us should we wipe each other out.
-Centipedes and Millipedes are closely related, and are notably among the grossest things ever- giant poisonous centipedes can kill and devour MICE.
-There's also the Arachnids, the eight-legged super-creatures of nightmares- Spiders, Tarantulas & Scorpions, among others. They have two parts to their bodies, and various types of eyes. Emperor Scorpions are HUGE, but less poisonous than smaller ones. Ticks & Mites are also part of this group.
-Because of their small size, insects aren't really major factors in most campaigns, unless someone is lucky enough to be made of bees or something. But really, comics could never create someone THAT weird, could they...? However, that's why GIANT INSECTS were created for fiction.
-Not only Giant Spiders, but you could also shrink the heroes down, thus having them face the EQUIVALENT of such things at their new size. Think Honey I Shrunk the Kids, but as super-heroes.
