Characteristics
Reported incidents of these sorts of creatures vary somewhat, but there are several basic characteristics that pop up over and over again. In most cases, the eyewitnesses describe a beast that is 4.5 to 5.5 feet (137 to 168 cm) tall, with an oval shaped head bearing alien-like eyes that glow red. Most descriptions claim that the creature has long, feathery spines that run from the back of its head down the spine, ending at the rump.
Many eyewitnesses report a strong, unpleasant sulfur-type odor, but others say that the creature has no smell. Some say the skin is similar to a frog's -- green in color with mottled specks; others claim that it has the appearance of furry lizard skin.
Although the creature generally ambles on two legs, it has been known to run on all four. Many assert kangaroo-like qualities, saying that the Chupacabra uses its strong hind legs to jump rather than walk. Others suggest a more ape-like quality to the creature's gait.
