The firedragons are a sort of dragonic hybrid that mixes many aquatic and amphibious forms
Their mouth is like a snake, with a sheathed tongue in the chin and a glottis. The glottis, however, is attached to a larynx that is shaped for growling and bellowing, akin to a dog. They also have a vocal sac like a frog. Alongside this is a gill slit opening in the back of their mouth, which can be opened or clamped shut. Their lungs are sack-like and resonant but can pump efficiently like a crocodile
While they could copy the sounds of their component animals, I would like to ask about if any new sounds could be produced by the collaboration of these bodyparts
