From wikipedia:

A bestiary, or Bestiarum vocabulum is a compendium of beasts. Originating in the Ancient world, bestiaries were made popular in the Middle Ages in illustrated volumes that described various animals, birds and even rocks. The natural history and illustration of each beast was usually accompanied by a moral lesson. Reminds me of course of Borges' Book of Imaginary Beings.

​Redditor gyyp imagines, with the help of photoshop, a compendium of beasts. I would love, as a writing exercise, to come up with a name and moral lesson for each. Anyone help?

Hraffonallard - The wit and temper of a duck with the grace and strength of a mustang, the Hraffonallard learns early on the emotional triggers of its opponents, delivering, on its powerful back, the one person that will undermine the confidence just moments before physical confrontation.​
