Wyvern

Wyvern is a large draconic monster.

Appearance
Wyverns have slim, brown bodies. They don't crouch on the ground like other draconic creatures, so they are quite tall when they walk. In fact, wyverns are better at running than flying - their wings are short and poorly connected to the body.

Unlike other draconids, wyvern feet are more like dinosaur feet than bird feet.

They have long, hooked claws on their wings. They are used to pin down prey, so when the monster walks, they are held upwards to keep sharp.

Wyverns possess S-shaped necks and large heads with long snouts. The jaws are filled with razor sharp teeth and end with short, hooked beaks. Inside of the mouth is black. Tongue is forked. Eyes are absent.

The monster's long, whiplike tail sports a spiky stinger, which contains potent venom.

Behavior
Wyverns are able to fly to some extent, by rapidly flapping their small wings, although they prefer to walk.

When they spot their victim, they usually charge, sometimes even taking off the ground and pin them down with sharp claws.

Then, they use their jaws or stingers to kill.

Wyverns are blind - still, they can sense body heat and possess acute hearing and smell.

Myths
Wyverns are widely known from medieval heraldry. Their portrayals are usually incorrect - wyverns lack eyes and pointy tongues and have shorter necks. Also, they are always brown, not green or yellow.
