- Alligator snapping turle (Exhibit vs. Habitat)
I've seen these guys in "exhibits" before in real life, more than one that was smaller than the in-game box. They don't move around much. All we'd lose from making them an exhibit animal is the potential to mix them with the alligator, but IMO that's not enough to include a habitat animal that, for all it sits around and does very little, will basically be a piece of scenery.
- Chinese giant salamander (Exhibit vs. Habitat)
Amphibians, especially critically endangered amphibians, need careful climate control. Again, I don't understand the belief that the in-game exhibits are small; they're actually gigantic. Sixteen square meters is huge.
- Green anaconda (Exhibit vs. Habitat)
- Reticulated python (Exhibit vs. Habitat)
- King Cobra (Exhibit vs. Habitat)
Snakes go in exhibits. Only in specific circumstances are they kept in open-air enclosures. Like all ectotherms, they require regulated temperature and humidity, so outside of their natural environment it's simply better animal welfare to keep them in terraria. Not to mention that snakes are notoriously good at escaping, and can be incredibly invasive.
- Radiated tortoise (Exhibit vs. Habitat)
- African spurred tortoise (Exhibit vs. Habitat)
Both are large enough to be habitat animals, and would behave similarly to the two giant tortoises we already have.
- Chinese softshell turtle (Exhibit vs. Habitat)
- New guinea snake-necked turtle (Exhibit vs. Habitat)
No reason to think these would be habitat animals.
- Argentine giant tegu (Exhibit vs. Habitat)
Similar to monitor lizards, so habitat.
- Frill-necked lizard (Exhibit vs. Habitat)
Smaller than the iguana, so exhibit.
- Two-toed sloth (Exhibit vs. Habitat)
- Slow loris (Exhibit vs. Habitat)
- Golden lion tamarin (Exhibit vs. Habitat)
- Senegal galago (Exhibit vs. Habitat)
All habitat, because Frontier hasn't given us any reason to think they'll deviate from ectotherms for exhibits. In any case none of these are suitable exhibit animals.
I cut out the last two because frankly I don't know why they'd be added to the game anyway.
