Pronghead

Prongheads are a species of predatory extraterrestrial which feature in the Discovery Channel’s 2005 special Alien Planet.

Description
Native to Darwin IV, Prongheads are largish bipedal creatures who are capable of bursts of incredible speed, observed at over forty miles per hour, which is more than fast enough to overtake their main prey, the herbivorous Gyrosprinters. Superficially similar to the theropod dinosaurs of earth’s prehistory, they are pack hunters, the wolves of Darwin IV, who will wear down their target either simply through the effort of the chase, or by inflicting a number of small stabbing wounds which will sap the creature of its strength. Once the victim has succumbed, the Prongheads will then pounce, and drain it of the fluids which are such a precious resource on Darwin IV‘s arid landscape.
