@TinoPup Looking through I've noticed a distinct lack of directional signs and indeed signage in general, which seems like it would give major difficulty in navigating and understanding the place.
@Great Argus I think I told you guys about this while I was there, but the only signs are the ones at the entrance of each section, which are a bit hard to notice. Other than that, there is nothing. No species signs, no direction arrows, no info about habitats.
@aardvark250 There is! If you happen to notice them peaking out from the stand when you walk in to the rotunda, where someone checks your tickets. It is only in French, and only mentions a few species, but that's more than the exhibits themselves tell you. There is an app, but I didn't want to kill my battery with it.
