Height: 8 to 10 feet

Length: 15 to 20 feet

Weight: 2,500 to 3,100 pounds

The Hellgrazer is truly an unusual creature. Its build and design suggest a predatory dinosaur - similar to the T-rex or Allosaur. Its heavy head, sharp teeth, and powerful legs seem like they should belong to a creature that preyed on other animals. But in actuality, the Hellgrazer is a strict herbivore. It uses its powerful jaws and serrated teeth to cut through tough vegetation, which is swallowed whole and presumably digested by powerful stomach acid.

Short-tempered and aggressive, the Hellgrazer lives alone. It roams through the grassy Savanna, as well as the upper and lower forests. Most creatures know its distinctive red and green coloration, and are wise to give it a wide berth. Anything that comes too close will likely not do it again. Its sharp teeth and powerful bite would certainly make an effective weapon, even for an herbivore. However, these are not its main defensive tool.

Like a few other creatures on this island (the Flash Beast and Greater Sea Dragon, for example), the Hellgrazer has the ability to spray fire from its mouth. When defending itself, there appear to be two streams of fluid that leave the top of its mouth, combine, and then combust into a flaming liquid stream. These may be two different chemicals it produces: a clear fluid from the left side, and a thicker, yellowish substance from the right. When these chemicals mix and ignite, the result is a devastating defensive attack that can critically burn, or even kill, the largest of allosaur species. 

Still, the Giant Rider can pose a deadly threat to the Hellgrazer. This massive flightless bird attacks by leaping onto its prey's back, where the Hellgrazer's flame defense is far less effective. The rider will then sink its hook-like talons into the Hellgrazer's flesh and make it almost impossible to shake off. At this point, the Giant Rider is able to deliver bite after bite with its razor-sharp teeth. This makes the bird the most dangerous predator of adult Hellgrazers.

Hellgrazers are not born with this fire-spraying ability, though; and have many more predators. Because they lack the characteristic defense of adults, youngsters are dull-colored and camouflaged in the forests of Mainland. Young Hellgrazers also have a more slender build, and rely on speed to escape predators such as allosaurs and riders.

• Naturalist Note: From the descriptions and illustrations provided by Daniel Mercer, we can reasonably conclude that the Hellgrazer is an abelisaurid, likely Carnotaurus, an ironic classification given that the name literally means "meat-eating bull."
  
  The flame spraying mechanism is unique and well-described by Daniel. It appears that the animal possesses a gland in its upper jaw that produces and stores an oxidizer, perhaps hydrogen peroxide--a substance that is already produced in cells naturally. (Hydrogen peroxide would also provide the heat source for ignition.) This would likely be the clear substance he describes. The yellowish substance would be produced and stored in another gland, and is likely an oily, fatty fuel.
  
  These two are sprayed out ducts in the front of the mouth. The pressure is produced either by a muscular contraction around the glands, or by compression from its tongue.
