Nylin

Short Overview
Nylin [nai:'lɪn] are horselike reptiles that are tan in the day, but at night, they glow in specific spots on their head and upper neck. They eat budding and flowering herbs. They walk a little more often than most animals alike it, so they have enough warmth in their body to sleep in the dim caves at midday. Because of this, they are noticed as the only known warm-blooded reptile. They live on the bioluminescent planet of Xrynn.

Colors and Breed Names
There are specific breeds of Nylin. The names are in the Xrynts language. They use the outer color of the eyespots first, then the middle, or the color of the mane, then the color in the middle of the eyespots. (as for the one in the picture, it would be Green-Orange, or Ziir-Zin'nyn)
