Good grief, this is astonishing. The other day I tried tracking down the names for various avatar species in VRChat. Surely someone had a list curated... but bing, google, and ddg all let me down with ancient wikis or completely unrelated sites, no matter my quoting or alternate search terms (animals, avatars, creatures, etc.).

Very first hit on millionshort: https://www.vrcarena.com/

Edit: Though, I'm still trying to track down a more comprehensive list. That one's missing Nanachis, which are rather common these days.
