Watch, a pterodactyl in it's natural habitat.

The pterodactyl first spots a protestor and a mark. The mark, having an alliance with the protestor, defends him.

The pterodactyl first screams in it's distinctive high pitched voice.
It then attempts to attack the mark with it's claws, but is defeated.

The pterodactyl, not one for giving up, continues attacking the mark, but once again lies on the ground defeated.

Truly a wonderful creature.
