Gila Monster (pronounced: Hee-la) Heloderma suspectum "Mollie" The scientific name, Heloderma , is derived from the Greek words "helos" and "derma" and simply means "studded skin." The species name, suspectum , was given because an early biologist suspected the animal to be poisonous based on the grooved teeth. And indeed, the Gila Monster is one of only 2 venomous lizards in the world, the other being the Mexican Beaded Lizard. Gila Monsters are hatched from eggs. They are America's largest lizard, usually attaining a length of 16 to 20 inches. (The record is 22 1/2 inches.) They are also the slowest moving lizard in the country making them easy victims for passing automobiles or mean natured humans. They have few natural predators. This specimen was born at the San Diego Zoo in California. Gila Monsters in captivity can live for 20 to 30 years. Because of their slow nature, Gila Monsters usually feed on baby mammals, birds or animal eggs. "Mollie" the gila monster eats small rats here at the Rattlesnake Museum.

AHSC Home Gila Monster The Gila monster and the closely related Mexican beaded lizard are the only kown venomous lizards in the world. These heavy bodied lizards are easily distinguished from nonvenomous species by the bead-like surface and yellow or coral colored pattern of their skin. They are described as shy and retiring reptiles, not prone to attacking humans unless they are significantly agitated. Arizona laws protect these fascinating animals from being captured or held in any manner. These large reptiles have a well-deserved reputation for clamping down on a victim with their teeth and not letting go. Most serious bites occur when the Gila monster's lower jaws secure a firm hold on the victim that lasts for several minutes. The bite is described as extremely painful, although initial pain is generally confined to the area of the bite. Victims may also experience localized swelling, nausea, vomiting, high blood pressure, weakness, faintness, excessive perspiration, chills and fever.

Gila Monster Heloderma suspectum During the winter, when the animals hibernate, they live off the fat stored in their tails. Threats habitat loss resulting from urban development and road building STATUS: IUCN VULNERABLE SIZE: Length: 15-23 inches (38-58 cm), largest lizard native to U.S. POPULATION Unknown, but presumably small CONSERVATION: CITES trade restrictions Reluctant Monster There is nothing very monstrous about the gila monster unless you're a young mouse or a baby bird. Gila monsters are the largest lizards native to North America, but they're less than two feet long. They live in the deserts of Mexico and the southwestern U.S., preying on the young of small mammals, nestling birds, and bird and tortoise eggs that they find in mesquite scrub. They are stout-bodied lizards with short legs and a short, fat tail. They're covered with bright irregular markings, usually pink, yellow or white, against black or brown scales. They are shy, retiring creatures unless they're provoked. Then they can be dangerous because they secrete a neurotoxin a poison that destroys nerve tissue from their salivary glands. In humans, their bite can result in severe pain and even death. Using their strong, thick claws, gila monsters can climb into low bushes in search of food, but they don't do it very often; they prefer to stay on the ground. In fact, they spend most of their time underground, often in the burrows of small mammals. In some areas, they are nocturnal; in others they are active during the day. During the winter, they hibernate.

Gila Monster Submitted by Omar Al-Ansari American School of Kuwait Hawalli, Kuwait City, Kuwait Gila Monster Source Unknown Photographer Unknown Description: The Gila Monster is one of the only two types of poisonous lizards in the world. There are two types of Gila Monsters. The Heloderma suspectum suspectum (Reticulate) and these adults are mottle and blotched. The second is the Heloderma suspectum cinctum(Banded) and these adults have a broad double crossband. The Gila Monster appears sluggish in the wild but it can quickly turn around and bite; when the Gila Monster bites its prey or its enemy, it holds on to it viciously. The Gila Monster's venom is as deadly as the venom of Western Diamond Back Rattlesnake. It is the only poisonous lizard in North America and is the biggest. The Gila Monster comes out at night and spends 98% of its time in a burrow that was built or stolen from another animal. In winter, the Gila Monster hibernates in its burrow and uses the stored fat in its tail that can keep it alive for months. The Gila Monster lays 1-12 eggs at one time. The eggs have a tough cover. This creature can live up to 20 years.

12:01 PM 9/3/1998 Rare Gila monsters provide Arizona desert thrills By JOHN and GLORIA TVETEN It is late on a midsummer night as we drive along a lonely dirt road that winds through a portion of southeastern Arizona's Sonoran Desert. Billowing storm clouds blot out the moon and stars, and lightning flickers all around. The rains have brought out many of the desert's nocturnal animals, and we have seen foxes, javelinas, owls and rattlesnakes. Numerous pocket mice and kangaroo rats bound across our path, while tarantulas and scorpions amble along at a more leisurely pace. Then our lights pick up a stocky, low-slung creature crossing the road ahead. Its bulky form and vivid pattern are unmistakable. It is a Gila monster, the first we have seen in 30 years. We can scarcely believe our luck, and we hurriedly jump from the car for a better view. This is a young animal, no more than a foot in total length and vividly marked with black bands across its bright orange body and tail. As it grows larger, the markings on this rare lizard will become more diffuse, and the orange color will fade to a salmon-pink. In spite of its tender age, the Gila monster has a belligerent bent. It backs slowly away at our approach, then turns quickly and snaps its powerful jaws whenever we venture too close.

An experimental drug has been developed from the Gila monster's saliva to improve memory and learning. The New York-based biotechnology company Axonyx Inc., which has developed the drug, Gilatide, hopes to use it in human trials later this year. The Gila monster's bite can be deadly, but its saliva contains a chemical which acts on a previously unknown receptor pathway in the brain that affects memory. The animal is native to the southwest United States and Mexico. It's good to be imaginative and inventive when looking for new treatments Richard Harvey, Alzheimer's Society The Alzheimer's Society has welcomed the development, although it has cautioned that any drug breakthrough could be a long way off.

Its coloring is marbled, a combination of brown or black with orange, pink, yellow, or dull white. The lizard's movements are slow and clumsy. It feeds on young birds and mammals and on eggs. Because the neurotoxic venom is produced by glands in the lower jaw and the grooved teeth through which it passes are set far back in the mouth, venom does not always enter the wound when a victim is bitten. The gila monster must fix its teeth deeply in a certain position to give a fatal bite. The only other member of the genus Heloderma

Not only is he following her signals, this particular Gila monster is also one of a select few that emit high-tech information to herpetologist Dan Beck of Central Washington Universityby means of miniature, temperature-sensing radio transmitters. "We've learned these lizards have an incredible sense of direction," says Beck, who has spent much of the past 15 years studying the creature and its travelsand is known among colleagues as Dr. Gila Monster.

(advertisement) Excerpt from Lizard Envenomations Synonyms, Key Words, and Related Terms: Gila monster, Heloderma suspectum, Mexican beaded lizard, Heloderma horridum Please click here to view the full topic text: Lizard Envenomations Background: Two species of venomous lizards exist, the Gila monster ( Heloderma suspectum, with 2 subspecies) and the Mexican beaded lizard ( Heloderma horridum, with 3 subspecies). The Gila monster is found in the desert regions of Arizona, western New Mexico, southeastern California, the southern tip of Nevada, extreme southwestern Utah, and northwestern Mexico. The beaded lizard is found only in Mexico, south of the location range of the Gila monster. Both lizards have heavy bodies with large heads and powerful jaws. The beaded lizard is larger than the Gila monster, reaching almost a meter in length, whereas the Gila monster's maximal size is approximately 0.5 m. Pathophysiology: The venom apparatus is much less sophisticated than that of most venomous snakes. A pair of multilobed labial venom glands (modified submandibular glands) lie in the anterior portion of the lower jaw. Venom is conducted from each lobe through a duct and is deposited into a labial mucosal pocket adjacent to the anterior teeth. The teeth (approximately 20 per jaw) are grooved and loosely attached to the jaws. Venom is conducted via capillary action along these grooves into the victim's tissues as the lizard bites and chews. The more irritated the lizard is when it bites, the more it salivates and the greater the venom yield. Effective envenomation in humans probably occurs in less than 70% of bites.
