Sand Dragon

Sand Dragons live in caves far out in the desert. They can grow up to 35 ft tall 100 ft long and speak sand dragonic. They have no wings, arms and legs like a worm with scales. Their head appears to be like one of a blue dragon but yellow and much larger. Their head can grow up to 40 ft tall. Their scales are yellowish brown and covered in sand. Sand dragonic is a language that only Sand Dragons speak. It is a harder to understand and learn version of draconic. Sand Dragons live alone and are quite rare. Only about 15 are known to exist and they can live for up to 200 years. They venture out for food in the desert but will only go 500 ft away from their lair. Their diet consists of animals and anything that dare come at least 60 ft within their territory. They are greedy and evil. they think for themselves and have hard scales. Their scales give them a lot of protection making them a enormous threat. They do have a weak spot on their stomach. They try to hide it as their flesh is incredibly weak. Their hunting tactics are to hide under sand and move towards the strongest vibration on the ground and jump out on it. Thus, huge vibrations can distract them from footsteps. They can only burrow through sand and very soft dirt. Their scales can be made into shields.
