Dinicthoid

The dinicthoid lurks in Pandora’s lakes and lowland waters waiting to strike. When hunting at night, the dinicthoid can pulse with bioluminescence to take on the appearance of a smaller, more docile creature to lure prey closer. Conversely, it can control its markings to appear even larger and fiercer. It also features a disconcertingly humanoid false face, (used to befuddle or frighten would-be predators), that is created by folds at the top of the skull. This ferocious predator uses its two large beak-shaped teeth to snare its food. Dinicthoids have a varied diet, which includes plant life and fish of all sizes. A school of these creatures can even bring down a small sturmbeest, if one were to wade far enough into a dinicthoid-populated watering hole. An adult dinicthoid can grow up to 10 ft (3 m) in length and swims by flexing its supple, muscular sides.
