In fact, opposite the aquarium area, you’ll see some displays. And one of those displays is about living fossils. The whole Main Hall area/Portico area is meant to just pique people’s interest as they come before they actually go through the museum proper.
Also, where we have the fish and the other interesting creatures—turtles—we have two animatronic dinosaurs and two animatronic children. These aren’t teaching exhibits; they’re just meant to get people thinking. And that’s why they’re there, just to challenge people.
