Tegu Caresheets
Author: Varnyard
This information is a generalization of the needs for the five basic Tegus that are found in the pet trade. Each species of tegu has additional requirements that are breed specific. You can read more about each specific species by using the links at the bottom of the page.Tegus are "new world lizards" found in the tropical rainforests, tropical woodlands, and arid scrublands of Central and South America. Specific species will come from specific areas and will be noted within their caresheet. Tegus are terrestrial (ground dwelling) for the most part, but they do like to climb and swim if given the opportunity. Tegus fill the same ecological niche as monitors, and they are an example of convergent evolution.Of the five major species found today, they divide into two separate categories. The categories separate tegus by the number of loreal scales they have on their snouts (see diagram below). The three species that are most closely related have two loreal scales; Red (Tupinambis rufescens), Argentine Black & White (Tupinambis merianae), and Blue (scientific name has not been determined as of yet). The Columbian Tegu (Tupinambis teguixin) and the Gold (Tupinambis teguixin teguixin) are closely related and each have only one loreal scale. The Gold tegu is a separate species from the Yellow Tegu (Tupinambis duseni), the Blue Tegu is believed to be a color phase (morph) of the Argentine Black & White and the Gold Tegu is believed to be a color phase (morph) of the Columbian Tegu.Enclosure:The basic rule of thumb for an enclosure is twice as long as the length of the reptile and as wide as the reptile is long. Specifics for species will be given within their caresheet. A hatchling can be housed in a 20-gallon aquarium, whereas a juvenile can be housed in a 55-gallon aquarium. If the enclosure is too large for the hatchling or juvenile tegu this can cause stress. Substrate:The recommended substrate is cypress mulch, orchid bark or eucalyptus mulch. The substrate needs to be 6" - 12" deep, as tegus like to burrow. Lighting:Ultraviolet light with a full-spectrum of light is recommended. Lights that emit UVB are a must for this species of reptile. Ultraviolet lighting is important in the production of vitamin D3, which is necessary for calcium metabolism. UVB should be use in addition to calcium with D3 and multi-vitamins. Lighting Cycle:A cycle of 12 hours of light and 12 hours of darkness is recommended.Heating:Each specific species has their own individual temperature need that will be discussed within their caresheet. An enclosure should be set up in zones. There should be a warn side, cool side and then a basking area. The use of under tank heating (a specific UTH made for reptiles can be used or a heating pad made for humans) is recommended along with the lighting mentioned above. NEVER USE A HEAT ROCK AS IT CAN BURN YOUR TEGU!Water:Tegus like to swim, so the use of two separate water bowls is suggested. Make sure one of the bowls is large enough for the Tegu to use as a pool. Change drinking water daily and pool as needed. Food:One of the most important things to remember is not to offer food that is larger than the area between the tegus eyes. Tegus are omnivorous as adults. They will eat both meat and vegetables. Hatchlings are carnivores and their diet should consist of crickets, small mealworms, and (mice) pinkies. The juveniles diet consists of (mice) fuzzies, large mealworms, crickets and boiled or scrambled egg (chopped). Adults diet consists of mice, large mealworms, crickets, super worms and boiled or scrambled egg, fruit and vegetables. Remember to dust crickets and worms with vitamin/calcium mixture before feeding to your tegu. See individual caresheet for more specific species food list. Adult Tegus diet will be almost equal parts meat and vegetables. Tegus can become very aggressive while feeding. Hand feeding could be dangerous, as the tegu may not recognize the difference between your hand and the food. Humidity:Tegus require high humidity levels of 60%-70% for proper shedding as well as proper health. Misting on a daily basis is required. If you have another way to raise the humidity, that is fine. Remember not to make the substrate tacky with too much moisture, or you may grow molds, which is not healthy for the animals.Hibernation:Tegus hibernate up to seven months in the wild. They will also do this in captivity if given the chance. However, tegus do not have to hibernate. If they do not hibernate, they may still slow down on feeding during the normal hibernating season. Tegus will consume great amounts of food in August to prepare to begin hibernating in September. They will hibernate from September to March and begin eating again in April. Hides:Tegus require hides at both ends of their enclosures. These can be made out of a half log or another safe structure. They can also benefit from a moist hide.

Columbian Tegu Caresheet (Tupinambis teguixin)
Author: Varnyard
(Taxonomy)Kingdom: AnimaliaPhylum: ChordataClass: ReptiliaOrder: SquamataFamily: TeiidaeGenus: TupinambisSpecies: teguixinOther Common Names for the Columbian Tegu: Colombian Black Tegu, Colombian Black & White Tegu, Common Tegu, Black Banded Tegu, Golden Tegu (Note that some people spell Colombian as Columbian)Remember the Golden Tegu is considered a color phase (morph) of the Columbian Tegu, so all information is the same for both tegus.The Columbian and Golden Tegu are native to Brazil, Peru, Colombia, Venezuela, Ecuador, Trinidad, Northern Argentina, Guyana, Surinam and French Guiana. They live in the tropical rainforests, tropical woodlands and arid scrublands. They are terrestrial but enjoy climbing and swimming when given the chance.Temperament:The Columbian and Golden Tegu are the most aggressive of the tegus that we are discussing. These tegus, if they feel threatened, will whip their tails and bite. The bite of the Columbian and Golden can mean a trip to the hospital for stitches. This is not a reptile for a beginner. Description:The Columbian and the Golden Tegu are medium size tegus reaching a length of 3 to 3 ½ feet in length. The female of the species is smaller than the male. The body is solid with powerful limbs. The head is large and the snout is tapered. They use their forked tongues to smell by carrying the scent into the Jacobsons Organ located in their mouth. Their tail is longer then their body and is rounded with bands at the end. Tegus have a stress point in their tail to allow break points, so you should never handle a tegu by its tail. Colorization:Columbian Tegu while young are black and bright green. Through shedding the tegus color changes until it reaches the adult color of black and white. Sexual Differences:The only sure way to sex a young tegu is by having it probed by an experienced breeder. There are several physical characteristics to assist in sexing an adult. Adult males will develop large jowls and be brighter in color then females. Males have a larger tail just posterior to the Cloaca. Males have a larger number of Femoral and PreAnal pores. Males also have two button shaped, enlarged scales in the Post-Anal Region.Enclosure:The basic rule of thumb for an enclosure is twice as long as the length of the reptile and as wide as the reptile is long. A hatchling can be housed in a 20-gallon aquarium, whereas a juvenile can be housed in a 55-gallon aquarium. If the enclosure is too large for the hatchling or juvenile tegu this can cause stress. Suggested size for a single adult Argentine or a Blue is 6 x 3 x 3 foot. Temperatures:The Columbian and Golden Tegu requires temperatures between 80-85 degrees Fahrenheit. Cool side should be around 78 degrees Fahrenheit. A basking area of 100-110 degrees Fahrenheit is required. The night temperature can drop to 70-75 degrees Fahrenheit.Food:In addition to the list mentioned previously, your adult Columbian or Golden Tegu might enjoy the following: cooked ground turkey, fresh fish (not from a pet shop, due to the chemicals used in these tanks), baby chickens, grapes, tomatoes, strawberries, melons, and just about any other soft fruit. Bananas can be given as well, but not as a staple diet, only in moderation. This is just a suggested list, each tegu will have his or her own likes and dislikes.

They live in the tropical rainforests, tropical woodlands and arid scrublands. They are terrestrial but enjoy climbing and swimming when given the chance.Temperament:Both the Argentine Black and White and the Blue Tegu are very docile and tame compared to the rest of the tegu family. They should be handled daily from hatchlings and will adapt to humans. They may wiggle and squirm around when handled but usually will not bite. Babies have been known to propel themselves on their back legs.Description:The Argentine is one of the larger tegus reaching a length of 4 to 4 ½ feet in length. Whereas the Blue is considered one of the smaller tegu, reaching a length of 3-3 1/2 feet. The female of the species is smaller than the male. The body is solid with powerful limbs.

They live in the tropical rainforests, tropical woodlands and arid scrublands. They are terrestrial but enjoy climbing and swimming when given the chance.Description:The Red Tegu is one of the larger tegus reaching a length of 4 to 4 ½ feet. The female of the species is smaller than the male. The body is solid with powerful limbs. The head is large and the snout is tapered. They use their forked tongues to smell by carrying the scent into the Jacobsons Organ located in their mouth. Their tail is longer then their body and is rounded with bands at the end. Tegus have a stress point in their tail to allow break points, so you should never handle a tegu by its tail. An adult Red Tegu can weigh up to 20 pounds and has a life span of 10 to 15 years.Colorization:Young Red Tegus appear bright green and black. As the tegu ages the colors will fade and change to a cream or brownish color. Adults will be light pink to cream to medium red. They will develop black spots and bands.Sexual Differences:The only sure way to sex a young tegu is by having it probed by an experienced breeder. There are several physical characteristics to assist in sexing an adult. Adult males will develop large jowls and be brighter in color than females. Females are reddish brown with white spots. Enclosure:The basic rule of thumb for an enclosure is twice as long as the length of the reptile and as wide as the reptile is long. A hatchling can be housed in a 20-gallon aquarium, whereas a juvenile can be housed in a 55-gallon aquarium. If the enclosure is too large for the hatchling or juvenile tegu this can cause stress. Suggested size for an adult Red is 8 x 3 x 3 foot.Temperatures:The Red Tegu requires temperatures between 80-90 degrees Fahrenheit during the day. A basking area of 110-120 degrees Fahrenheit is required. The night temperature can drop to 75-80 degrees Fahrenheit.Food:In addition to the list mentioned previously, your adult Red Tegu might enjoy the following: cooked ground turkey, fresh fish (not from a pet shop, due to the chemicals used in these tanks), baby chickens, grapes, tomatoes, strawberries, melons, and just about any other soft fruit.
