The Mexican Amphithere (scientifically known as Draco Americanus Mex) is significantly longer than its american cousin with a length of 45 feet, thrice the American Ampithere's length of 15, without including the 6 foot long red tongue which it uses to catch prey. Their height is roughly the same as the American Amphithere's at 5 to 10 feet.

Another difference with american amphithere's are their bird like wings in contrast to the American's moth like ones. It is believed that the dragon inspired the Aztec god Quazocoatil and that while Mayan civilisation existed they were worshipped and fed which is depicted Mayan walls. Even now Mexican Amphitheres return to Mayan ruins looking for food (although they have now reverted to their natural diet of lamas and other large land mamals).

They are described by Mayans as like a winged serpent and have a long thing body with a very long tail ending in what has been described by many as a fan. They have bright yellow eyes; dazzling iridescent green-blue scales along the neck, back, and tail; a purplish sheen to wings; a paler green belly; feathers that are similar in colour but brighter plumage during the summer breeding season, when the main and tail feathers turn a golden colour.

In the mating season they gather in a flock high above the Mexican Gulf crying out with loud parrot like squawks. Lairs are found near water, with their nests resembling coracles containing three hard eggs. Eggs are able to float and are brown with orange markings. Chicks have to wait in rocky holes for three years until their wings grow.

Mexican Amphithere's are perhaps most noticeable trait is its lack of legs although research upon skeletons of Amphithere's shows that there extinction was not complete: they have vestigial legs bones which are hidden within their skin and which are very similar to those of snakes. They also have a easily identifiable swooping flight path.
