From the species creator, Talshear:

Small wyvern with spines along it's back and acid breath
Also known for their large eyes and true omnivorous nature

these spines are plentiful and almost hair like, they have a better grip on their wings for greater stability, no head horns.
Extra info that makes no difference, they can collapse their ribs
They can squeeze through tight spaces so they have to reflect that slightly
