Not only a list of animals, but to what they are used too. It looks like life of Yliakum people is highly connected with differet aimals. We need to know about these if we are supposed to RP there.
I have also small suggestion. Animals shouldn't look like some ugly creations from some cheap horror. I suppose the monsters which are created for now are supposed to look bad, so that you have no doubt that you are doing the right thing, killing it... but that is not the right direction. Do we have any animals like these IR ? Not really.
For example hippopotamus, it is big and sometimes can be really dangerous (seriously, it isn't so peacefull as you could think) sound like example of PS monster. What is the difference? Hippopotamus isn't really ugly, each animal IR has some beauty, while in PS they don't. Wolves, tigers, do we have in PS any animals agile in smiliar way?
What about livestock animals? These also has some certain shape and line.
