Does your fantasy world have zoos.
Nearly all fantasy worlds have fantastical creatures, but how many of them are kept in captivity by the various races? If so, then how knowledgeable are they in terms of natural science (geology, geography, biology, evolution, ecology, etc).
In the real world, menageries were a place that rich and powerful people can view their private collections. It wasn't until the 19th century that zoos as we know them took off. Modern zoos are now used for conservation and education.
