About 5 to 10 feet high, and 45 feet long.
Bird Like. Feathery. Very long tail, and also has a slender body. It has no legs. It has an enormous red tongue (up to 6 feet in length) used to catch prey when in flight. Its swooping pattern makes it easy to spot from a distance.
Dazzling iridescent green-blue scales along the neck, back, and tail. Paler green belly. Feathers similar in colour but way to much brighter plumage during the summer breeding season, when the main and tail feathers turn a golden colour. Purplish sheen to wings. Bright yellow eyes.
Loud squawk, reminiscent of a parrot.
Depending on the location, the Mexican amphithere will eat any larger land animals.
