Super quick concept sketch of a lesser drake idea.

Polar sea drake, diet consists primarily of seals, small whales and fish.  Capable of short periods of time on land when moving across ice floes, it spends the majority of its time in the water.  Thick layers of blubber serve to cushion its organs and keep the drake warm in its frigid habitat.  Like all members of the dragon family it is extremely hardy and warm-blooded, but is not a true dragon and lacks the ability to breathe fire.
