The Sorin in the picture is a male and the bright colors on the male glow in the dark.

--Here is some Info on a Sorin.--
On planet DUNTUNE, Sorin's is a horse-type desert mammal with a mixture of both horses and Deer-like behavior so yeah they do prance like a deer. They're mostly found nearby barren canyons, Red grass plains, and giant tree mushroom forests. Sorins are faster and stronger than normal horses even though the male Sorin is slightly bigger with dragon-like horns, and more muscular than the females. Their diet is Red Grass Hay, Coral tree Fruits, Rats, and Mushrooms, and also they enjoy the animal foods from Earth, and the reason why they love those animal foods from Earth is that it's new. The Sorins are very friendly and domesticable, they're passively tamed by giving them a kibble food of grind-up rats, fruits, and mushrooms all in one kibble... It's nasty to look at but they sure do like it.

Artist Note: This is all the info I have for the Sorin species so far, more info will be revealed later.
