Well, I technically didn't "invent" this fictional species, only drew this quick concept layout (IngramTalonshade did, so credit goes to him for inventing them)!

That being said, I don't know much of the details of this species of his, but from what I can recall for the adults ~

• They're a hybrid of an iguana and simian traits

• Males have green scales and average build compared to the females' yellow scales and taller/skinnier figure.

• Both have dark grey fur on their body with some light grey patches unique to each individual.

• Have 4 fingers from birth, but gain an extra digit only on the dominant hand.

• Fur eventually darkens and greys out with age, and patches change color when they mate (which match with each other)

• Can give live birth or lay eggs, but depends in certain circumstances.

• Gain the ability to camouflage naturally with age.

Pretty sure there's more specific info about them, but that's my friend's business and I was just doing this as a little Christmas gift for him and a way of saying thanks for being a friend to me!
