Life in the Zoo by Sir David Affenburg

The famous wildlife documentary film maker Sir David Affenburg has just started a new project: a Zoo-Doku. He has spent a lot of time filming, and has just returned from Japan to start editing. To his dismay, he finds that he is unable to reconstruct the lay-out of the zoo from his notes, because of the peculiar characteristics of this zoo. Here are his notes; can you help him reconstruct the lay-out?

The zoo is shaped like a square and aligned north-south and east-west. There are two north-south walkways and two east-west walkways. These 9 sections are divided by two north-south fences and two east-west fences. The resulting areas are filled by 9 facilities and 72 distinct animals that can be grouped in 8 categories, Water animals, Birds, Great Cats, Megaherbivores, Reptiles (which include Snakes and Crocodiles), Apes, Bears and Rodents. In each north-south and east-west line and each section (divided by walkways), there is exactly 1 facility and 1 animal from each category. Habitats for animals from the same category cannot touch each other, not even diagonally. The same rule applies to facilities.

There are four facilities located on the outside. The entrance faces south and is placed to the right of a walkway. On the other side of the walkway are the Koi Karpers. The ticket office is located as close as possible to the entrance. The other facilities on the outside are the Souvenir Shop and the Parking lot. The animals on the outside ring are Walrus, Koi Karper, Barracuda, Swordfish, Flamingo, Vulture, Uhu, Puma, Cheetah, Tiger, Leopard, Camel, Buffalo, Rattle snake, Caiman, Chameleon, Mandrill, Orangutan, Rhesus Monkey, Gibbon, Grizzly, Black Bear, Sun Bear, Kodiak Bear, Alpine Marmot, Beaver, Paka and Vole. The restaurant can only be reached by a tunnel and offers a magnificent view of (clockwise) the Crane, Zebra, Panda, Alligator, Capibara, Chimpansee, Octopus and Lion. From the watchtower, one can see in one direction (in increasing distance) over Jaguars, Gorillas, Elephants, Ravens, Pythons, Sea Lions, and Kodiak Bears. In another direction one can see (in increasing distance) Hammerhead Sharks, Ibises, Giraffes, Bonobos, Komodo Dragons, Porcupines and Tigers.

On the corners of the four NS-EW intersections are the following animals and facilities: Daycare centre, Toilets, Manta Ray, Lion, Ocelot, Okapi, Gazelle, Zebra, Gnu, Alligator, Baboon, Chimpansee, Polar Bear, Spectacled Bear, Squirrel and Prairiedog. Animals in habitats that do not border the outside or a walkway are Sea Lion, Serval, Lynx, Rhinoceros, Elephant, Giraffe and Porcupine. Next to the education center are the Uhu, Squirrel and Sea Lion, and of course a walkway. The day care center shares its walls with the Pelican and the Sloth Bear. The souvenirshop is next to a walkway, the gorillas and the Pakas.

After studying the footage, several more conclusions can be made. The capuchins share a fence with the vultures, and the polar bears share a fence with the Gila monsters. The gnus share a fence with the basilisks, and the walrus shares a fence with the mandrills. The lynx shares a fence with the cobras, while the koi karpers share a fence with the black bears. The orangutans are in the same region as the chameleons, and the caimans are in the same region as the toucans. The ostrich and the leopard are on the same east-west line. The Rhesus Monkey and the Hutia are on the same north-south line. The alpine marmot is on the same east-west line as the Sun Bear. The Himalayan Bear is on the same east-west line as the Swordfish. The camel is on the same north-south line as the beaver. The barracuda is on the same east-west line as the Puma. The clownfish is on the same north-south line as the okapi.
