Animals are everywhere in Sea of Stars and in so many varieties. The initial pool of animals was similar to that here on Earth, with a few exotic variations, but the Sundering changed everything, sometimes for the better, but usually for the worst. The raw magic released by the sundering changed animals in all sorts of strange ways, though the most common was changes in size, which is why there are giant rats and miniature giraffe in the Sea of Stars, but sometime the changes were stranger leading to tree dwelling sheep and six-legged oxen, or creatures became mixed and dangerous, creating such beings as stagwolves and sting squirrels.
People in some regions were forced to adapt to chickens that ate wood and laid eggs that were shelled like nuts, aquatic cows or replacing transport animals with zebra and other such adaptions which then became just the way things were done in that valley or these islands. In other words, for those who travel widely, especially venturers, it is wise to not take the animals you encounter at face value without consulting with the locals.
Zoos and menageries is the Sea of Stars are always looking for new and exotic additions to their collections, gatherer of such creatures can make a good living . . . if they do not get eaten first.
Notes: Z is a tough letter to end on, but I hope still fun.
