*Note: You can’t go back to the chapter 5 island “Guarma”. Some animals e.g. macaws only live there and may be missable, it’s currently unclear if these affect the trophy.
Preliminary list of missable chapter 5 animals (by user ‘EphemeralEcho’, it’s everything found so far but until someone has the trophy we won’t know if it’s complete or not):
Parrots: 1. Blue & Yellow Macaw 2. Scarlet Macaw 3. Great Green Macaw
*There may be more missables animals. We won’t know for certain until someone has the trophy. For now, do everything possible in chapter 4 and keep a save at the end of it. Then finish the game and do the other trophies. When everything has been found you can reload the old save, get the chapter 5 animals, and replay the game from there.
*Note: You can’t go back to the chapter 5 island “Guarma”. Some animals only live there but aren’t needed for “Skin Deep” or “Zoologist”. There are multiple confirmations on this. The animals exclusive to Chapter 5’s Guarma island (which are not needed and can be skipped) are: the 3 native Guarma parrots – Blue & Yellow Macaw, Scarlet Macaw and Great Green Macaw, the 4 native Guarma snakes – Sunglow Boa, Rainbow Boa, Red Boa and Fer-De-Lance, and lastly the other native Guarma bird – Red-Footed Booby.
The rest of the Guarma animals does spawn on the main map: “Cuban Land Crab” & “Green Iguana” spawn on the main map, on the largest of the islands in the Flat Iron Lake on the East side of the lake and directly West of Rhodes just off the shore.
