(Sketchy thing to show the difference between the main Ender Dragon species)(This is a modded Minecraft au, mimic dragons are the dragons from Dragon Mounts 2)

Ender Dragons are split between three types: Monarch, True, and False
-Monarch Ender Dragons are the largest wyrms in existence. They possess four horns, each unique to the individual and a point of great pride. They’re also well-known for their brighter colors and distinctive star shaped pupils. They are one of the few species that can move through dimensions as they please.
-True Ender Dragons are bigger than false Ender Dragons but smaller than Monarchs. They possess a single pair of horns and lack the spikes on their jaw but do have visible ears unlike Monarchs. They tend to be black, dark greys, blues, and purples, and have grey, sometimes white, horns. They are typically around 9-10 feet tall and 23 feet long.
-False Ender Dragons are a result of mimic dragon eggs being surrounded by endstone and other various End materials or hatched in The End itself. They’re smaller than True ender dragons at around seven to eight feet tall but can mimic pretty much everything except their ability to control endermen. Mimic dragons can be found naturally occurring in just about every realm and naturally take on the elements of the environment around their egg at their time of hatching.

-Monarch and True Ender Dragons typically have a naming theme.
-Dragon in general, including diurnal dragons, have tapetum lucidum, vomeronasel organs, and heat pits lining their lips.
-The human/villager/illager hybrid babies of Monarch/Trues occasionally have more earthy tones.
