There are people that insist that something like a "boring" animal does not exist.
Personally, I think that this is only partly true; of course, almost every animal has something interesting to offer-yet it depends on the individual willing to discover this "special" and on the means needed to do so. Therefore, for most people, a lion is more interesting (even if it sleeps all day long) than an antlion, and a bear is better known to them than a water bear. This attitude might change at least in some individuals when being introduced to and discovering the "micro-fauna"; however, for many, many people, only the mentioned mammals are top attractions they're willing to pay for.
I think that a lot of sympathy/antipathy torwards certain species is based on personal experiences as well as on Your social surrounding. As a small child. the little sister of a friend of mine was terribly afraid of dogs-just like her mother. The first thing she did when she moved out to live on her own as an adult was to get a puppy...
This btw is also a reason why I think zoos, as well as national parks, botanical gardens etc., are tremendously important on a very fundamental emotional level: at least judging from my personal observation, I'd dare to say that positive experiences at an early age (like petting a friendly goat, feeding a giraffe or just thehappy family trip in itself) can have a very long-lasting effect in terms of the individual's future relationship to animals & nature.
The lack of interest Pygathrix admits to have in terms of the smaller mammals or "pet-shoppy" reptiles is a typical aspect of human nature: the more common something is for You, the less interesting & observable and thus more "boring" it becomes. So if Indris, water civets or pacaranas were as common in zoos as their relatives mentioned above, I'm sure they wouldn't turn a head in terms of enthusiastic zoofans.
The latest version of the "Rare-animals-I-want-to-see-in-zoos" in this thread just illustrates this: no zoofan would be highly interested in kodkods or mountain tapirs if they were a dime in a dozen in most zoos. And I dare to say that f.e. a walia ibex is most likely just as "boring" as any other ibex.
Maybe we're all like little spoiled kids who just don't appretiate what we have and wish for what we cannot have. I'm not excluding myself here; like I mentioned in another thread, a zoo completely or mainly (sic!) consisting of the most common pet species wouldn't sound all too attractive-while I would jump at the opportunity to watch Arabian leopards or Saolas. Nevertheless, I freely admit that I also have a soft spot for more than one species/breed of domestic/pet animals as well as for individuals of the pet shop-reptiles-often due to positive personal experiences with them; and I acknowledge that these critters are also important for the zoo in terms of education.
What I do find boring is not the particular animal, but how the animal is presented in zoos. In recent years, zoos have become more and more uniform; if based on zoogeography, it's usually (very simply put) like:
Africa = lion, zebra, giraffe, elephant, meerkat, gorilla, RRH, flamingo; maybe a antelope or two and white rhinos
Asia = tiger, Orang-Utan, Oriental otter, fallow deer, Reeve's muntjac
America = mara, rhea, llama/alphaca, marmoset, macaw, bison
Europe = ibex, fallow deer...
Australia = Bennett's wallaby, emu, budgie, Bearded Dragon
"Seal" equals California sea lion or Harbour seal; penguin = Humbolt Penguin, etc. etc.
After visiting a few zoos in a row, You start to feel like visiting stores of the same chain which differ only slightly locally: "Meerkats on Your right next to the lions, flamingos next to the zoo entrance & gift shop"; it's this uniformity and lack of boldness to be more creative that I consider boring; the occurance of the very same species again and again just adds to this. This doesn't mean that You can't have a fine zoo with the common creatures; but to do so, You also have to be more creative. Rhine Zoo is a nice example for that; quite a bunch of zoos aren't.
