Flying Gators look and behave very much like winged Alligators or Crocodiles. The single pictorial example of a Flying Gator shows they are green in color with a small pointed spade at the end of their tails. Though the apearence may seem like they only have a rear pair of legs, they actually have all four. The front pair is within the binding of the picture but apon closer inspection this is so. It appears they can breathe fire as most dragons can.
A group of Flying Gators are referred to as a "goggle."
Flying Gators are not known for their intelligence. The Incomplete Book of Dragons reveals that they can be easily fooled by mimicking the sound of a poisonous dragon (such as the clicking of a Toxic Nightshade) and they will instinctively scatter, though humans clearly do not look like a dragon!
Flying Gators inhabit marshlands such as the Haunted Marshes and often stay submerged in the water so that only their eyes show. They wait quietly for unsuspecting animals - even other species of baby dragons—to wander into the water, and then strike.
Flying Gators are mentioned once in this Book, as Hiccup notices what is aboard the Roman ship.
|“||An enormous number and variety of dragon species were being held prisoner behind the bars of this cage. Deadly Nadders, Flying 'Gators, Big Spotted Gormlesses, Yellow Vampires, Common or Garden Dragons - you name it, they were all there, trapped together in a furious tangle of talons and wings and fangs, ready to be sent back to the restaurants and shoemakers in Rome.||”|
