well, the way i see it, the monster hunter world consideres wyverns as the base species, which can have several differant reletives. it works like how reptiles not only have lizards, but snakes, turtles, and amphibian which are a sub breed of reptile. hence why they dont classify monsters as mammals or insects, because the monster hunter universe is differant from ours.

but heres my list of monsters and how they pretain to their species.

WYVERNS: any form of reptillean creature in the MH universe.

flying: two legs, two wings

bird: two legs, two wings OR two, legs, two arms, and have avian features.

psuedo: two legs, two winged arms

fanged: four legs, no wings

amphibian: four legs, no wings, and are aquatic

serpent: four inferior legs, no wings, snake like skeleton

piscine: two legs, two wings, and are aquatic

HERBIVORE: any harmless creature in the MH univrerse.

PELAGUS: any mammal in the MH universe.

NEOPTERON:any insect or arachnid in the MH universe.

CARAPACHEON: any crustateon in th MH universe.

LAVIATHEN: any aquatic, non winged monster in the MH universe.

ELDER DRAGON: anything that cant be classified as the ones listed above.
