Mystery at the San Diego Zoo

Yesterday I got to visit the San Diego Zoo. It's gigantic! The Australia section was one we explored in depth. The San Diego Zoo has the largest group of koalas outside of Australia.
We also took a behind the scenes tour of the zoo, which allowed us to feed the camels, okapi and giraffes and look at the back of some exhibits. I was immensely happy to be licked by the giraffe. Out of all the animal kingdom, their tongues are my favorite. Camels have prehensile lips, and giraffes have prehensile tongues. Also, a random fact, if you watch a giraffe swallow, you can see the food go all the way down.
After that we got lost trying to find the arctic section. Neither my aunt or I are very good at directions, and the map was kind of messy, so we went in circles and around to random hidden places. We saw some cool things we wouldn't have otherwise seen, though. There was a secret aviary with quiet, colorful birds from all over. The pigeons were especially pretty, surprisingly. Some forest pigeons are green or blue, and one, the blue-crowned pigeon, was a foot and a half tall and had a lacy crest of feathers on its head. We did finally find the arctic. The polar bears were sleeping near the window, huge and impressive. Some polar bears can stand at heights of up to ten feet on their hind legs!
We tried to go back a fancy way by trying to go through the forest section. It's a cool walk. The San Diego Zoo also has an enormous variety of plants from all corners of the earth. They grow all around the path, obscuring all noise and views from other sections. It feels like walking in the middle of a jungle, far away from all civilization. That's all well and good, but it was getting dark, and the signs were confusing and unclear. We still didn't understand the map so we wandered where we thought was the right direction. We went deeper and deeper into the jungle, losing sight of all human signs. We found more weird aviaries and side paths, and found ourselves climbing. Then we were stuck way up in the air, wandering around lost like crazy people. Finally we found people and made it back through sheer luck. I think the zoo managers should probably check to make sure there's no Narnia-like land back there with strange sprites rearranging signs. I think I may have to believe that.
Anyways, I also have some information on the Sunburst Diving Beetle, which was at the zoo. This beetle is about 1/2 an inch long. It has a black body with bright yellow spots on the wing case. The Sunburst beetle primarily lives in water, but can also fly to find another water source. Like the other beetles in its family, it has large, strong back legs for swimming.
Since the beetle still breathes air, it holds a small bubble at the end of its body to use as a sort of scuba tank.
The Sunburst Diving Beetle lives in ponds in the southwest United States. Its diet consists mostly other bugs and larvae it finds in the water.
