Changewing

The Changewing is the master of camoflage. They can be very agressive. But if you're not a threat, they can be somewhat mischevous and playful. These dragons have a similar social structure to a pride of lions.

Appearance
They have eyes closetogether on the top of their heads, with a long snout. They have cheek horns that make almost a moon shape, with the points pointing behind their heads. They have two long antennae with spines that look like leaves or thorns, that are almost as long as their body themselves. They have short legs and a wide body, with triangular wings. They have spines that look leaf/thorn like in appearance too, that go all the way to the tips of their tails. They are usually red in colour when not camoflaged, but they can also come in other colours.

Abilities
They have the ability to change the colour of their skin to match almost perfectly to their environment, making them near invisible. Their spines and antennae help break up the shape of their body to help them blend. They like to mimic what they see as well, imitating movements of whatever is moving. It helps them blend in with wind rustling through leaves in a tree, but also means they may copy other dragon, or human behaviour.

Instead of fire, these dragons can spit a highly corrosive acid. They can start using this acid spitting as soon as they are hatched from their, strange glowing eggs.

Strengths and Flaws
Though they have colour changing properties, it means that their hide isn't as thick or as armoured as other dragons. If they have nothing to camoflage against, they will revert to their original colours. Mostly the females do the hunting and defense of the pack.

Habitat
Rocky terrain and forests. They can be very territorial and protective of their kin.

Preferred Training Methods
Playing with them seems to help, and making similar noises to them.
