The “Lagarto overo”, “Tegú overo”, “Iguana” (Tupinambis teguixin) is a species of lizard Teiidae family. It has a total length of 1.5 m, in exceptional cases, the most common length meter in total length. (the specimen pictured here was about 1.10 m). Its geographic distribution includes Argentina (in the provinces of Misiones, Corrientes, Entre Ríos, Formosa, Chaco, Santa Fe, Buenos Aires, the central eastern and southeastern Córdoba and northeast and southeast of La Pampa), Bolivia, Paraguay, Uruguay, Brazil and Venezuela. It is also reported in Colombia. This species is considered by some authors Merianae Tupinambis synonymous, others treated separately. If treated separately Tupinambis teguixin is related to Tupinambis longilineus and geographically distributed in northern South America and Amazonia. While Tupinambis duseni, Tupinambis rufescens and Tupinambis merianae is primarily distributed south of Amazonia. Because they are cold-blooded animals (poikilotherms) can not internally regulate internal body temperature; this affects their behavior, being active during the warmer months of spring, summer, autumn and winter while hibernating in caves that they build or leaving other animals such as “vizcachas” (Lagostomus maximus). Your time of peak activity is between 11 and 16, from this popular saying “sunbathing as lizard”. In adult individuals the dorsal coloration has a more or less dark brown or olive-yellow background, with transverse black bars from the neck to the tail, sometimes replaced by black or white blotches in other cases do not have spots or bands but a color blackish or greenish brown fairly uniform. The young at birth are clear metallic green, bright. Adults weigh between 3.5 and 4 kg. They have good triangular head, which differs from the body, large eyes, round pupils. The eyes have nictitating membrane. The ventral area has small scales. Feet with five toes with strong nails. The hind legs have longer fingers. They have well-developed tail, dragging, can detach as other lizards (can regenerate again). Males are larger and stronger than females, are at increased development at the base of the tail, where the male sex organs are housed two hemipenes, withdrawn. According feeding are carnivores and omnivores. They feed on fruits, vegetables, insects, arthropods, fish, frogs, rodents, birds, etc. They are true generalists, as they grow. Juveniles are insectivores. The male differs from the female by having a stronger neck, jowls form, with its much wider tail at its base and because typically experience greater size and bulk. Keep in mind that they are very susceptible to stress and not willingly take us to approach them. A typical sign of dissent is raised on all fours, slowly snaking tail while snorting inflates and deflates the lungs. If you feel cornered, will rush quickly trying to bite or scratch with their claws.

Hello Hernan,
A well known animal to me. I think it's the same species as I posted a few months ago. For me it was a big surprise.
Beautiful photo in good sharpness and natural colours.

Ciao Hernan, great capture of fantastic creature, I never see before, fine details, splendid sharpness and wonderful colors, very well done, my friend, ciao Silvio

Hola Hernán,
Wonderful Iguana, the composition is as perfect as without the tail it could be. The big, sharp, b/w lizard makes a gorgeous contract with the rather uninteresting fore- and background. Good photo overall, I like it.
Best regards, László

Hello Hernan,
What a neat looking lizard you have posted for us. The all B&W colors are very unusual and therefore quite attractive. It appears to be very well fed and in excellent shape. It also seems to have a massive tail which looks very thick and stout.
You have done a fine job of presenting this fine looking specimen in excellent detail and natural colors. Great job!!

It is a huge lizard and has been well captured, Hernan.
The patterns on the subject are very distinct.
Thanks and regards.

Bonjour Hernan,
Un lézard bien grand, je crois que j'aurais peur..
Bon cadrage horizonal, peut-être un petit manque de lumière.
Un posting intéressant.
Merci et bonne soirée

Very interesting species, with good lighting and details. The decision to 'cut off' the tail is a pity but it shows the strength of the animal. Good note too.

An AMAZING image of this black and white monitor lizard.Excellent details on the scales on the skin.
