Type studies about Dart Poison Frog

I have the poster (art project) and my topic is about the Dart Poison Frog, so I’m still think about the type studies of it.
* So here is the instruction
Type studies: Select the best relevant word sets ( word pairs or short phrase per study) that define the forest species. It should be 2 -5 words so please help me to be creative as much as you can. Thank you so much. 
I just attached some example about the type studies but it is in a different topic.
