Found in flocks mainly in wetlands and on lakes, the tetrapteron is a four-winged, flamingo-like creature with a twin tail, which assists balance as it hunts for fish. There are two types of tetraperton: aquatic and arboreal. Although similar in appearance, the aquatic birds have longer necks and legs for life in the wetlands. The tetrapteron have excellent long distance vision, and can detect movements as little as an inch from over 145 ft (45m) away. While many predators on Pandora nurture its young, none take more care of its offspring than the tetrapteron.
