Zoologist Ivan Sazima first observed the behavior while on a nature walk in search of interesting animal interactions. What he probably didn’t expect to find was a male black-and-white tegu getting his freak on with a long-deceased female companion.
A lizard's penis evolves six times faster than any of its other parts, according to a new study.
Experts have long predicted that warming temperatures will be a veritable death sentence for most types of lizards, but the scientists behind a recent Proceedings of the National Academy of Sciences (PNAS) study have found one species that has adapted quite nicely.
One tiny tree-dwelling lizard in Boreno displays these colors year-round, not as a tribute to the Captain of Man's Salvation, but as a way of appearing like a falling leaf as it glides from branch to branch. The camouflage keeps it from being easily spotted by birds and other predators.
Scientists working on islands in Florida have documented the rapid evolution of a native lizard species — in as little as 15 years — as a result of pressure from an invading lizard species, introduced from Cuba.
Researchers at Arizona State University have taken a giant step towards uncovering the genetic secrets behind lizards’ ability to regrow their own tails, and believe the knowledge could be used to stimulate regrowth in humans.
Field and laboratory work by Omar Torres-Carvajal from Museo de Zoología QCAZ, Pontificia Universidad Católica del Ecuador, and his former undergraduate student Simón Lobos has resulted in the discovery of a gem-looking new species of shade lizard from the cloudforests in northwestern Ecuador.
A recent lizard inventory project has confirmed the occurrence of 21 lizard species, two of them being the first records to the fauna of Qatar, the Persian leaf-toed gecko and the Gulf sand gecko.
The ancestor of snakes and lizards likely gave birth to live young, rather than laid eggs, and over time species have switched back and forth in their preferred reproductive mode
New research shows that chameleons use their color-changing abilities to communicate with other chameleons, particularly in battle.
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...
