Some Commonly Found Creatures in US Swamps
Sourced from varied websites
Mixture of Freshwater and Saltwater Denizens
Now the majority of these creatures will not be suitable for an encounter. Things like a Fox, Rabbit, Vole, Bats, etc. Others could be encounters like Bears, Bobcats, especially the Alligators or Crocodiles. Another issue with this list is that is for both Fresh and Saltwater so if you pull them all in at once,
it would be a severe mishmash. However to get an idea as to what creatures may be living in a swamp, it should be most suitable.
