Usually the very top one that you see on the right hand side is all public maps. The rest down below or more of custom maps from FH+ I believe. Such as Watermill and other maps like that. Unfortunally FH+ is no longer able for download since Simba took it down for reconstruction. He should post another version of this on the regular map section which ill provide for ya here

Which also answers your second question on where to actually get maps. From the provided link above you are able to download maps that users have created for the public to use. When downloading a map, make sure you read the little "Read Me" notepad that it usually comes with for informational instructions on how to input maps.
Three, there is no hunting nor is there a action command for attacking or eating, or anything like that. Thous functions were never introduced and won't be unless you create it on your own for your person reasons. Kov is the only one to update action commands and unfortunally he's no longer here.
Thous animals you are likening seeing are made meshes from users and imputed in maps.
Anything that you ever wanted to download from more items to mass masking can all be found here:
