Wyverns

In Squawk pterosaurs are divided into two groups based on body plan (see also Imps.) "Wyverns" are large, short-tailed and long-necked. Wyverns are the largest flying animals known. These aerial giants are sometimes called flying dragons and some Wyverns do have long toothy snouts for fishing like many dragons, but others have toothless beaks or even stranger headgear.
