Praxian Tribal beasts are not Earth animals
Praxian tribal beasts may look like their Earth counterparts and be generally the same size and weight, but that’s as far as it goes in most cases. They eat different food, drink much less water, their general behavior, and their mating details are different. Unlike their Earthly counterparts, all but herd-men are ridden, and all produce milk for consumption. In the Wastelands, the major tribe’s herds are mostly the offspring of Storm Bull and Eiritha, so all males are bulls, all females are cows, and babies are called calves, regardless of their earthly names.
Major Tribe Herd Beasts
Bison are visually and behaviorally based on the North American Bison (Bison bison bison).
Herd-men are based on modern humans (Homo sapiens sapiens). They are physically identical, with identical growth patterns, but with only animal intelligence. Their behavior can be roughly based on those of living primates of the Pongidae family; orang-utans, bonobos, chimpanzees, and gorillas. There are many sources of fiction, such as Planet of the Apes by Pierre Boulle and its spinoffs that can be used as examples of humans as animals.
High Llamas are based on an extinct ancestor of the camel, Aepycamelus giraffinus, formerly called Alticamelus. This very tall prehistoric camel lived from the middle through late Miocene period. Visually it is based on museum skeletons and reconstructions, and behaviorally on Bactrian camels (Camelus bactrianus). High llamas are not humped like earth camels.
Impala are visually and behaviourally based on the Impala (Aepyceros melampus).
Sables are visually on the Giant Sable Antelope (Hippotragus niger variani) and behaviourally on the on Sable Antelope.
