Named 'mountain dweller', it is the highest-altitude living member of its genus Germán Chávez and Diego Vásquez from the Centro de Ornitología y Biodiversidad (CORBIDI) in Peru have discovered a new colorful lizard which they named Potamites montanicola, or "mountain dweller". The new species was found in Cordillera de Vilcabamba and Apurimac river valley, the Cusco Region of Peru at altitude ranging from 1,600 to 2,100 meters. Their...

Mini Reptiles Discovered In Madagascar
2012-02-15 08:41:19

Researchers have discovered four new species of miniature lizards in Madagascar, including one so small it can easily perch on the tip of your finger or on a match head, report scientists in the upcoming Wednesday issue of the open access journal PLoS ONE. Brookesia micra, the tiniest chameleon ever discovered, grows to just about an inch (30 mm) long from nose to tail. All four species discovered belong to the genus Brookesia, known as leaf chameleons, which already contains some very...

Lizard Study Analyzes Importance Of The Founder Effect
2012-02-03 05:54:43

A team of American researchers have reportedly completed what they are calling the first experimental study of the phenomenon known as the founder effect -- the loss of genetic variation that occurs when a new population is established created using a small group from a larger existing population -- in a natural setting. The researchers, whose work was published online Friday in Science Express and is scheduled to appear in the print journal Science on February 17, "had an unprecedented...

[ Watch the Video ] Robots, like lizards, need a tail to remain upright when they stumble during leap University of California, Berkeley, biologists and engineers including undergraduate and graduate students studied how lizards manage to leap successfully even when they slip and stumble, and found that swinging the tail upward is the key to preventing a forward pitch that could send them head-over-heels into a tree. The scientists subsequently added a tail to a robotic car they...

Extinct animals hide their secrets well, but an exceptionally well-preserved fossil of an aquatic reptile, with traces of soft tissue present, is providing scientists a new window into the behavior of these ancient swimmers. According to the study published in PLoS ONE's November 16th issue, the fossil, characterized by a team led by Johan Lindgren of Lund University in Sweden, is from the mosasaur family, a group of reptiles that lived between 65 and 98 million years ago. The fossil was...

Gila monsters are large venomous lizards. Although envenomation by the Gila monster is not often fatal to adult humans, it results in intense pain, swelling, weakness, and nausea. A team of researchers, led by Stephen Galli, at Stanford University School of Medicine, Stanford, has now uncovered a natural mechanism by which mice reduce the toxicity, and thereby the morbidity and mortality, of Gila monster venom – immune cells known as mast cells release the protein MCPT4, which degrades...

Researchers Produce First Genome Sequence Of Lizard
2011-08-31 12:43:03

  Researchers have produced the first genome sequence of a lizard. The green anole lizard is the first non-bird species of reptile to have its genome sequenced and assembled. Researchers have assembled and analyzed over 20 mammalian genomes, but the genetic landscape of reptiles remains relatively unexplored. "Sometimes you need to be at a certain distance in order to learn about how the human genome evolved," Jessica Alföldi, co-first author of the paper and a...

Anoles show they can solve novel problem, remember solutions Tropical lizards may be slow. But they aren't dumb. They can do problem-solving tasks just as well as birds and mammals, a new study shows. A Duke University experiment tested Puerto Rican anoles on several cognitive tasks and found they can learn and remember to solve a problem they've never faced before. The results challenge the scientific stereotype that reptiles have limited cognitive abilities and methods for finding food. The...

Until a recent discovery, theories about the origins and evolutionary relationships of snakes barely had a leg to stand on.Genetic studies suggest that snakes are related to monitor lizards and iguanas, while their anatomy points to amphisbaenians ("worm lizards"), a group of burrowing lizards with snake-like bodies. The debate has been unresolved--until now. The recent discovery by researchers from the University of Toronto Mississauga and the Museum fr Naturkunde Berlin, Germany of a tiny,...

The great desert burrowing skink, a lizard living on the sandy plains of Central Australia, has been discovered to live in family groups within elaborately constructed tunnel complexes. Published in PLoS One, researchers Steve McAlpin, Paul Duckett and Adam Stow from Macquarie University, in partnership with Parks Australia, found that family members of the great desert burrowing skink contribute to the construction and maintenance of burrow systems that can have up to 20 entrances, extend...

The Desert Iguana, Dipsosaurus dorsalis, is one of the most common lizards of the Sonoran and Mojave deserts of the southwestern United States and northwestern Mexico. They also can be found on several islands in the Gulf of California. Their preferred habitat is largely contained within the range of the creosote bush, mainly dry, sandy desert scrubland below 3300 ft. It can also be found in rocky streambeds up to 3300 ft. In the southern portion of its range this lizard lives in areas of...

The Brown Basilisk or Striped Basilisk, Basiliscus vittatus, is a species of lizard native to Central America, but have been introduced into the wild in the U.S. state of Florida. They are also called the common basilisk and, the "Jesus Lizard" because when it flees from predators it runs very fast and can even run on top of water. Basilisks actually have large hind feet with flaps of skin between each toe. The fact that they move quickly across the water, aided by their web-like feet,...

The Southern Alligator Lizard, Elgaria multicarinata, is a lizard native to the Pacific coast of North America. It is common throughout Southern California and can be found in both grasslands and urban areas. Several subspecies can be distinguished, including the San Diego alligator lizard. It has a prehensile tail up to twice the length of its body. Like many lizards, however, it can drop its tail if attacked, possibly giving it a chance to flee; the tail will regenerate, but will never...

The Beaded Lizard or Mexican Beaded Lizard, Heloderma horridum, is a venomous lizard found in Mexico and the southern United States. Adult Mexican Beaded Lizards range from 13 to 18 inches in length. Until recently, the beaded lizard and the Gila Monster were the only two lizards known to be venomous. Research showed that some iguanas and monitors are also venomous. The beaded lizards' venom is similar to that of some snakes (e.g. the western diamondback rattler).

Chuckwallas (less commonly known as Chuckawallas) are large, bulky lizards found mainly in arid regions of the southwestern United States and northern Mexico, although some are found on coastal islands. There are five species of Chuckwalla, all within the genus Sauromalus; they are part of the iguana family, Iguanidae. The name Chuckwalla derives from the Shoshone word "tcaxxwal" or Cahullia "caxwal", transcribed by Spaniards as "chacahuala". Physical description Reaching a total...
