I was just looking at this again and I can't believe I didn't notice the toad before! It's so obvious now. Based on their website, I would think a marine toad? Unfortunately I didn't take many exhibit sign photos here, it was too busy, but hopefully someone familiar with the place will know based on the two being together?
Wow! It costed me a lot to find the frog, that I never would have seen if not by your comment! It doesn't looks like a bufonid toad to me, it seems more in the line of a tree frog, but I'm fairly ignorant in anurans so who knows.
