The graboid is a fictional species of sandworm that acts as the primary antagonist of the Tremors series of films.

As Suzanne Ferriss and Mallory Young explain, the "destruction of 'graboids', as they are quickly dubbed, becomes the central tension of the film".[1] The creature made its debut in the 1990 film Tremors (although the name "graboid" was only mentioned briefly), and reappeared in its three sequels and the Tremors: The Series television series.

The graboid is based on the Mongolian death worm, a worm-like cryptid that purportedly attacks animals, and possibly humans. Within the film world, it is store owner Walter Chang (Victor Wong) who names them. The only other person in the first film to use the term "graboid" is Val McKee (Kevin Bacon). In the second movie Earl Bassett (Fred Ward) recalls the name "graboid".

According to UGO.com, "graboids are to the desert what sharks are to the ocean".[2]

Physiology[edit]

Graboids are depicted as subterranean animals, superficially resembling gigantic worms or grubs, with long, serpentine bodies. When fully grown, a graboid will measure up to 30 feet (9.1 m) long, and 6 feet (1.8 m) across at their widest point, and weigh 10-20 tons. Graboids completely lack eyes; they do not need them, due to living underground. Their heads consist of a massive, black, armored beak, which is used to push aside the dirt whilst digging. The beak opens up like a grotesque flower; it consists of a wide upper jaw, a thinner lower jaw, and a pair of hooked mandibles on either side. Whether they possess a skeleton or not is unknown, though a faux scientific document written by the SyFy channel hypotheses they have a semi-rigid internal structure, similar to the internal cuttlebone of cuttlefish.

Graboids have a trio of long, powerful, serpent-like tentacles, which are prehensile and have a reach of at least 10 feet (3.0 m). Each of these tentacles (which have been loosely compared to functioning like the creature's tongue) terminates in a toothed mouth of its own. It is unclear if they actually bite off and swallow food on their own, or if they are simply used for getting a better grip on prey so it can be dragged into the gullet. Normally kept retracted in the graboid's throat, these tentacles were initially mistaken for the actual creatures, causing the characters in the first Tremors film to underestimate their underground opponents. The graboid's common name is derived from these prehensile tentacles, which "grab" prey and suck it back down the graboid's hungry gullet. At times, these tentacles appear to have minds of their own, hissing and writhing like snakes. Food is typically swallowed whole, though early in the original Tremors film, they are shown to dismember and decapitate their prey.

A graboid's hide is thick and leathery, with a rough, pebbly texture, giving them a reptilian appearance (though they are not reptiles). This makes them very hard to kill with anything short of saturation bombing or large-bore rounds. Graboids possess immense physical strength, able to topple over mobile homes, tow along an object heavy as a pickup truck without slowing down, smash through brick walls and pull an entire station wagon underground. Encircling their bodies are short spikes, which all move in unison to push the graboid through the dirt, similar to the setae on an earthworm. They are able to burrow faster than a human can run; a graboid in Tremors 3: Back to Perfection was able to keep pace with Burt's truck. With armored head and mobile spikes working together in unison, a graboid can "swim" through the loose soil at high speed like a shark in the water, though they are incapable of tunneling through solid rock. Graboids (and their imago forms, the shrieker and ass-blaster) have distinctive orange blood. Graboids also have a powerful stench, which is made evident on several occasions throughout the first film. Though underplayed in the 2nd and 3rd films, the graboid's stench becomes a critical plot point in Tremors 4; Juan is able to identify the graboids as being the unseen killers in the silver mines later in the film due to them sharing the same vile odor.

Behavior[edit]

Graboids are shown to be ravenous carnivores, always on the hunt for food. Indiscriminate eaters, their diet includes sheep, cattle, horses, donkeys, coyotes, and humans. They are known to be cannibalistic when the opportunity presents itself; El Blanco consumed an ass-blaster in Tremors 3. Lacking eyes or a nose, they are shown to hunt by sensing seismic vibrations which are produced by sounds and movements (such as walking). Because they are unable to tell the difference between edible and inedible vibration sources they adopt a policy of "eat first, ask questions later", swallowing whatever sets off their vibration sensors and regurgitating anything that is inedible. Inedible objects can be spat out with considerable force, being propelled high into the air. Due to the sensitive hearing they use for underground navigation, graboids are so sensitive to sound they must retreat from loud explosions, which cause them great pain.

Graboids are ambush predators, preferring to sneak up on their quarry, though they are shown to chase it down with great determination. They erupt from the ground and use their tentacles to ensnare prey, pulling them into their mouth (sometimes only the tentacles break the surface). The tentacles wrap around the prey, biting into its flesh or hooking the prey with their horn-like spikes. When prey attempts to flee by climbing (for instance onto the roof of a house or car), graboids will dig away the earth under the hiding place, undermining it until it collapses or sinks low enough to allow the graboid to pluck off the prey. When they are unable to break down the prey's hiding spot, the undaunted graboids will continue circling it, like sharks at sea, until it ceases making vibrations. Usually they wait so long the prey dies of dehydration or starvation, i.e. several days.

Graboids are depicted as highly intelligent, possessing memory and the ability to learn. For instance, in the first Tremors movie the characters successfully killed a graboid by having it swallow homemade dynamite. The second graboid (nicknamed "Stumpy" by Val) had apparently noticed this trap and simply regurgitated the dynamite. Other examples are when the characters escaped on a bulldozer which was too big to be toppled (weighing 30 tons) or undermined (it could drive away before the graboids had a chance to dig away enough of the dirt under it), the creatures dug a trap in its path.

Shrieker[edit]

Shrieker
Scientific classification
Kingdom: Animalia
Phylum: Bilateria
Genus: Caederus
Species: C. mexicana
  • The second stage of the graboid life cycle first seen in Tremors 2.
  • Unlike their previous incarnations, the huge, subterranean and limbless graboids, shriekers live on the surface. Much smaller than graboids, shriekers are about 5 feet (1,50 m) long and 4 feet (1,20 m) tall. While graboids are worm-like in shape, shriekers slightly resemble dinosaurs or heavy ground-dwelling birds, having stout, three-toed legs and a compact body. They also have a short, stump-like tail. This tail, as well as some small bulges in the neck, has some orange coloring on it. Its function is not mentioned.
  • The one thing that shows shriekers are related to graboids is their skull- just like a graboid's, it consists of a powerful, beak-like armored upper jaw and a much narrower lower jaw surrounded by two mandibles. Both the jaws and the mandibles have sharp hooks and serrations to hold on to prey. The beak is very powerful; shriekers are capable of ripping through sheet metal with ease. While graboids have three prehensile tentacles for tongues, complete with jaws, shriekers have more normal tongues: singular ones lacking jaws. Like a graboid's, the tongue is relatively stiff (for a tongue). It can be stretched out approximately 3 feet (90 cm) and has some short bristles on it, not unlike the tongue of a cat.
  • The shriekers' most notable feature is their heat sensor, a brain-like pulsating organ atop their head which is usually covered by a frill-like flap of skin, which is supported by a small ridge at the base of the skull. Using this sensor, shriekers sense infrared heat, which is their only sense other than taste and touch as they lack eyes, ears or a nose. As shown by shots in Tremors 2 depicting the creatures' point of view, the heat sensed by the shriekers is apparently processed into an image highly similar to that of an infrared camera.
  • Shriekers are much easier to kill than graboids, being smaller, surface-dwelling and more easily damaged by firearms, although they hunt in groups. Like graboids, shriekers have orange blood.

Hunting and intelligence[edit]

  • Unlike the solitary graboids, shriekers are pack hunters, using their numbers to bring down large prey. In Tremors 2, the graboids appeared to spawn 3 Shriekers per worm. However, in Tremors 3, Burt discovers that one graboid can spawn 6 from itself. It is likely that the exact number varies, somewhat like the number of pups in a dog's litter. Shriekers are able to hunt in packs. By eating sufficient foods of any kind and getting enough to eat, they have the ability to multiply. The creatures are hermaphrodites, being able to double a number every few minutes. In Tremors 3, the six Shriekers were able to spawn an entire herd in under 12 hours. Sensing heat, they let out loud screams (earning their name). While the sound is useless (as they are deaf) they produce a lot of heat when screaming, alerting each other to the presence of prey. Another thing unexplained in the films is the shriekers' ability to "see" heat before raising the frill covering their heat sensor; they always seem to know when to raise it. It is explained on the Stampede Entertainment FAQ that they can see some heat through the frills. Raising them merely enables them to make full use of the obviously delicate sensory organ, similar to opening one's eyes widely.
  • When hunting shriekers show some good feats of insight and cooperation, using each other to form natural ladders to reach prey hiding on high ground such as rooftops.
  • Graboids, hunting by vibrations, often attack inedible objects, and the heat-seeking shriekers are no different. They have been observed attempting to eat warm car engines, electronic cables and steamed clothes.
  • Shriekers also feed on cold objects which they find by dragging their tongue over the ground. They have been observed eating military rations, and could possibly also feed on plants, which would make them omnivores.

Ass-blaster[edit]

Ass Blaster
Scientific classification
Kingdom: Animalia
Phylum: Bilateria
Genus: Caederus
Species: C. mexicana combustus

It is the third and final stage of the life-cycle including the graboid and shrieker. The ass-blaster appears in Tremors 3 and an episode of the TV series. It is named in Tremors 3 by Jodi Chang (Susan Chuang), the niece of Walter Chang, who named the graboids in the original Tremors.

Physiology[edit]

  • Also like shriekers, ass-blasters have bird-like legs ending in three-toed feet, and their feet have three slender black talons. The ass-blasters' most striking features are their wings – they have red/pink-colored sail-like structures at the back of their bodies, consisting of a semi-translucent skin supported by rigid stems. A third dorsal sail extends from the spine down the back and tail. Ass-blasters use these wings to glide through the air. In order to take off, they produce an explosion from their rear ends, earning them their name. This is achieved by mixing two chemicals near their colon (by shaking their hind quarters). Creature Designers Tom Woodruff and Alec Gillis borrowed this design from the real life Bombardier Beetle. The mix explodes upon exposure to air, launching the creature into the air. The ass-blaster also learns at an extreme rate and can easily comprehend how to use its natural means of transportation as a torch, such as when one attempted to melt through a fire door in Tremors 3. Ass-blasters have been known to spontaneously combust when accidentally poked with sharp flaming objects.
  • Like the other life cycle stages, ass-blasters have orange blood.

Hunting and intelligence[edit]

  • Ass-blasters hunt like birds of prey, scanning the ground for prey while gliding on hot air currents. Their heat sensors are much wider than shriekers', allowing them to view large sections of land at the same time. Judging from shots in Tremors 3 depicting the ass-blasters' point of view the heat they sense is processed into an infrared-camera-like image, just like how shriekers see the world. An ass-blaster's heat vision is much more detailed than a shrieker's. Like the other creatures, ass-blasters are also attracted to inedible heat sources such as fires.
  • For reasons unexplained in the film, unlike their previous form Shriekers, an ass-blaster will slip into a coma after eating, instead of multiplying.
  • Like the other life cycle stages, ass-blasters are intelligent, capable of learning from their mistakes. When several ass-blasters were blown up by being shot with burning spears fired from a makeshift potato gun in Tremors 3, one ass-blaster quickly learned to dodge these projectiles.

Life cycle[edit]

Fan made life cycle diagram
  • Graboids are hatched from eggs laid by ass-blasters (the final stage in the life cycle), as indicated in Tremors 3. These eggs split open diagonally. Carbon dating has shown that the eggs can lay dormant for at least 300 years, explaining why graboid sightings are rare and random. As shown in Tremors 4, the hatching of the eggs is prompted by warmth- in Tremors 4 hatched eggs were found in a hot spring.
  • Baby graboids (nicknamed Dirt-Dragons, and by the fan-base, Shooters) are 4 feet (1.2 m) long and are much shorter and compact in comparison to the adults, but already have the typical set of jaws and mandibles. The baby graboids also have a row of armored scales on their backs for protection, which are shed before they fully mature.
  • Like adults, they have large spikes used for digging; extra large rows of spikes sprout from the sides of their body. Being smaller than the adults, baby graboids are able to hurl themselves out of the dirt to tackle prey, like "some kind of demonic trout", according to Hiram Gummer. Their tentacles are underdeveloped at this point in their lifecycle.
  • Upon maturing, graboids will resume attacking and consuming prey. After that, they will seek a secluded spot where they will metamorphose. Three to six shriekers will emerge from their body where they have been growing in large sacs, killing the graboid. The exact number of shriekers that emerge could possibly depend on how well-fed the graboid is.
  • Upon emerging, shriekers will search for food. When having eaten a sufficient amount of food, shriekers will spit out a cocoon containing a mini version of themselves. This ability to reproduce asexually allows them to greatly expand their numbers over a short period of time, although it is unknown whether a shrieker can produce more than one clone. The newborn shrieker is fully developed, about 10 inches (25 cm) long and starts growing right after birth.
  • When a shrieker is around 12 hours old, it will undergo a moulting process, turning into an ass-blaster. Ass-blasters can live up to several years (an individual sold to Siegfried and Roy in Tremors 3 was still alive two years later). They attack anything warm. While shriekers reproduce asexually when they have fed enough, ass-blasters, slip into a coma when they eat a large amount of food. They can reproduce, however – each ass-blaster carries a graboid egg in its gut. Because they cover large distances when flying, they can carry these eggs further away, as theorized by Jodi Chang in Tremors 3.

Origins[edit]

  • The graboid's evolutionary origins are intentionally kept very vague; the creators of the film were unconcerned with this detail, offering no explanation as to where the graboids came from in the original film, (wanting to avoid the typical clichés of the monster movie genre.) The main characters even satirize this convention by attempting to guess where they came from- outer space, nuclear mutations, genetic engineering and prehistory are all offered up as possible explanations.
  • The answer was revealed in Tremors 2, when a fossil graboid spike was discovered and dated back to the Precambrian, making it at least 600 million years old- the graboids are apparently from earth, or have at least existed on earth for a very long time. Strangely, no prey large enough for graboids to eat had evolved yet at the time; in fact there was no life on the land at all, and most of the land was composed of bare rocks. A write-up written by the SciFi channel for Tremors: The Series retconned this by saying the fossil was incorrectly dated and actually from the Devonian period. By that time, prey big enough for graboids to eat had evolved (amphibians), though they don't rule out a possible extraterrestrial origin.
  • Whether the subimago Shrieker and imago Ass-blaster always hunted using infrared or whether this is a more recent adaptation is unknown, although in either the Precambrian or Devonian periods there would've been a complete lack of warm-blooded prey.
  • It is unknown if the imago and subimago forms were always part of the graboid life-cycle or if they are the result of becoming reproductively bound with another species, but the distinctly vertebrate-like appearance of the subimago and imago stages and apparently invertebrate nature of the larval stages would seem rather difficult to explain otherwise, save perhaps as being basal pre-vertebrate chordates whose metamorphosis loosely resembles their evolutionary history, much like the larval stages of amphibians resemble fish.

Film appearances[edit]

There are three varieties of Graboid shown in the films.[3] This number can be expanded to as many as four (juvenile dirt-dragons as larva, "adult" graboids as pupa, Shriekers as subimago, and Ass-blasters as imago) or reduced to as few as two (Dirt-Dragons as larva and Ass-blasters as adults; similar to the sharp lexical division of amphibian metamorphosis into tadpole and frog/newt). Their division into three forms seems to be based on habitat or locomotion: subterranean Dirt-Dragons, terrestrial/cursorial Shriekers, and aerial Ass-blasters.

The standard graboid, seen in all four films, is a subterranean animal, resembling a gigantic worm or grub, with a serpentine body, four massive, black, armored beaks on its head, and no eyes. Instead of hunting visually the graboids find their food by sound; they are also able to sense ultrasonic signals as demonstrated in the third Tremors movie. It also has several spikes on its sides that it uses to push itself along underground. The juvenile form of the graboid is about two feet long and looks somewhat similar to the adult form. The younger graboid has a proper beak (without the three separate jaws that form the lower part of the beak) and lacks the trio of serpentine tentacle tongues. Also, since they are not strong enough to pull a victim underneath the dirt, they instead propel themselves out of the dirt with extreme speed to take down a moving target. These young graboids are seen in Tremors 4: The Legend Begins wherein the characters refer to both juvenile and adult graboids as "Dirt Dragons". Graboids are also intelligent and learn very quickly. For instance, in the first film, when two graboids discover that the bulldozer is too heavy to lift, they simply dig a trap in its path.

The full adult form is about thirty feet long.[4] Graboids have a trio of long, powerful, snake-like tentacles, which are prehensile and have a reach of at least ten feet. Each of the three tentacles has a small, tooth-filled mouth and two horns. They often seem to have minds of their own. They die as soon as the graboid they belong to does.

In Tremors 2: Aftershocks, "Shriekers" are introduced. Fully grown graboids die while giving birth to a random number of creatures depending on the amount of food they consumed, between three and six, these creatures are the shriekers. Much smaller than graboids, about 6 feet (1.8 m) long and 4 feet (1.2 m) high, shriekers live above ground and resemble a small dinosaur, with stout, three-toed legs and a compact body. They have similar beaks on their heads, but lack the tentacles of a graboid instead having a single, long tongue, and like graboids lack eyes and noses, but they don't have ears. Shriekers find prey through a retractable, heat seeking crest on the top of their heads as well as their tongues which they use to find cold food through taste. They are hermaphroditic and will gag up small shriekers as long as they find food.

The third stage, the "ass-blaster", is introduced in Tremors 3: Back to Perfection. Shriekers turn into ass-blasters, which resemble their original shrieker, shedding their skin as they grow and change. They are capable of gliding with the use of red/pink-colored sail-like structures at the sides of their bodies, consisting of a semi-translucent skin supported by rigid stems and a third dorsal sail that extends from the spine down the back and tail. In order to take flight, they shake and quiver their tails and backsides and seem to be mixing two liquids which produce an explosion of flames from their rear end, similar to a Bombardier beetle's blast of acid. Ass-blasters fall into a "food coma" when eating too much and carry graboid eggs within their bodies, supposedly bringing the life cycle full-circle.

Other appearances[edit]

In the television series, the townspeople live more or less in harmony with a thirty-foot albino graboid named "El Blanco". As the animal is sterile, it lives on instead of giving birth to shriekers. Since graboids have been declared an endangered species, it may not be killed by the townspeople, who in turn profit from their valley being declared a protected habitat.[5] However, despite this, Burt Gummer is allowed to and even hired to hunt down and kill other Graboids, presumably as they aren't sterile and will turn into Shriekers. During the series, Burt and his sidekick Tyler hunt down and kill a Graboid in a town obsessed with aliens. Also, the government wanted one Graboid to be alive and since El Blanco is, they are likely satisfied as they had agreed to let Burt hunt Graboids again if helped them capture one alive. The townspeople also have to deal with Shriekers a couple of times and the Ass-Blaster captured in Tremors 3.

Steve Traiman writes, "MCA piqued consumer interest for the direct-to-video title Tremors 2: Aftershock with the graboid Game, which challenged Web site visitors to hunt for the giant worms featured in the movie."[6]

In Final Fantasy XI there is a "Notorious Monster" named Glavoid, an alternative romanization of graboid. Its design is very similar to that of graboids from the Tremors movies.[7]

In the roguelike game Cataclysm there are graboids and giant worms who behave in a similar pattern to Graboids in Tremors[8]

Both the graboid worm form, and the Shrieker form can be seen on display at the Lone Pine Film History Museum in Lone Pine, California.

Collectible replica[edit]

In 2006, Mania.com revealed that "Sideshow Collectibles and ADI have announced their reproduction of the original graboid design maquette...based on the creature from the film, which spawned two sequels, a prequel and a television series" and "created by the effects company ADI, led by Alec Gillis and Tom Woodruff. Jr. Each piece is reproduced in fiberglass and polystone, hand cast and painted. The piece is designed to display on any desktop or table, and also features wall-mount brackets for hanging display, like a hunter's trophy."[9]
