Latest Lizards Stories
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.
University of California, Berkeley, biologists and engineers 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.
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.
Gila monsters are large venomous lizards.
The green anole lizard is the first non-bird species of reptile to have its genome sequenced and assembled.
Anoles show they can solve novel problem, remember solutions.
Until a recent discovery, theories about the origins and evolutionary relationships of snakes barely had a leg to stand on.
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.
It's long been accepted by biologists that environmental factors cause the diversityâ€”or numberâ€”of species to increase before eventually leveling off.
Researchers at the University of California, Santa Cruz, have found that a species of lizard in the Mojave Desert lives in family groups and shows patterns of social behavior more commonly associated with mammals and birds.
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...
