In the world of Kei Murayamas (a centaurs life) our world took a different path of evolution, leading to the many different races we learn about in the manga/anime. With the exception of fish, animals in their world look different from ours as they have six limbs. Humans are only considered a mythical creature to them.
Centaurs were once a warlike species. It was common to train all centaurs, male and female alike, in the art of archery. Some of the younger generations though, like Himeno Kimihara, just participate to please their elders.

Angelfolk
WIP. One legend about the angelfolk's wings is that they evolved in order to protect them from the cold.
Antarcticans
Antarcticans excel in natural sciences and technology. It is offensive to call them snake people since they are mammals, which more closely resemble birds than snakes. Antarcticans jaws have little strength, so they don't bite hard. Their skeletons also don't have a wide rib structure so they cannot swallow food whole and the only Antartican who can lay eggs is the queen.
The last name of every member of the species is Quetzalcoatl Sassassul who also an exchange student from Antarctica, also informs us about her species' fear of swimming and deep water since falling in the water is a death sentence in Antarctica. By principle, most normal citizens and soldiers are female. Not much is know about their daily lives. The Antarcticans understanding of art is logical riddles and equations. The Chi-chans once called her Dinosaur-sama, a fact that humored Sassassul.
