The "Normal" type of Pokemon tends to have a Terran sort of cell structure. In many ways, they behave like normal animals, sometimes being confused for such. However, the "moves" Normal-type Pokemon can use vary greatly from the Earthly norm. With Normal-type powers and abilities, some Pokemon have the capacity to regenerate themselves, move at speeds unknown to other animals, shoot concentrated beams of energy, and even explode.
"Flying" type of Pokemon seem to be some offshoot of the Normal type, and as a rule tend to have wings or some kind of flight apparatus. Like Fighting-type Pokemon, they have hyper-dense muscle, but only in the muscles along and around the wings. This allows Pokemon of the Flying type to generate enormous aerial force, some even able to cut things with their wings or generate G-force winds.
"Bug" types tend to be quite interesting, as they generally share a symbiotic relationship with a sort of non-Pokemon creature, the Blood Mite (Sanguiparvulus utiliparasitus), living in its blood stream. Such Pokemon of the Bug type end up resembling Earth arthropods themselves, as well as acquiring some abilities shared with arthropods here on Earth (sapping bodily fluids, generation of silk, etc.). Most of the Bug types have exoskeletal armor along with their internal skeletons, which tend to be weaker as a result.
Does Drapion have 'blood mites?' If so, why is it not a Bug type? And if not, how can it have chitin?
So, the Blood Mite does not Pokévolve (my term for evolution in the Pokémon sense), which is reasonable, of course. How does the Blood Mite react when its hosts evolve? Their bodies change drastically and suddenly, as is the case with Kricketot to Kricketune, rather than the more-realistically-applicable transition of Caterpie-Metapod-Butterfree.
Are there some Bug-types, aside from Bug-type Arceus, being as it is and exception, that do not have any or any particular symbiosis with the Blood Mite?
Additionally, would it be possible for you to compile all this information on the Blood Mite onto a separate piece, for categorical purposes?
Generally, Blood Mites will reproduce like bacteria some time before evolution to compensate for the host's sudden need for huge amounts of chiting.
A fascinating note on Arceus: it becomes a Bug type via a Plate, because the Plate is actually created from the chitin of Blood Mites. Aside from creatures like Arceus, though, there are no Bug-type Pokemon as of yet that have been found without the Blood Mite.
And I may compile information on the Blood Mite in something about non-Pokemon creatures on the Pokemon world.
In the Pokémon World, how should one define what is Pokémon and non-Pokémon? To differentiate that the Blood Mite is one of the few non-Pokémon animals on the planet? I would think that the capacity to generate and store such massive amounts of energy would classify it as a Pokémon, but you could clarify the terms.
......also, how do Blood Mites...appear? Are they within a Pokémon, fresh in the egg, or they do they acquire it later?
I think you have heard of the velvet worm. Velvet worms....like to use String Shot on their prey. Velvet worms are cool like Pokémon.
All Pokemon can trace their ancestry back to Mew (Primordium mew), a small mammal-like creature. Mew and its descendents were unique in that their development from child to adult somewhat mimicked their evolution; fossils of tiny, rat-like creatures (now known to be juvenile Mew) have been found with larger Mew. The Blood Mite, meanwhile, does no such thing; its development starts from a single cell, morphing into a tiny, water-bear-like animal, without any clue as to how its evolution took place. We can only infer its ancestry from fossils and gene coding.
Interestingl enough, the Blood Mite is the reason why there is a Bug egg group; from conception, they form a symbiosis with the embryo. By the time the Pokemon hatches from its egg, its chitinous shell is already fully formed.
