Pythons are still a little venomous by Ed Yong National Geograpnic According to popular knowledge, venomous snakes are in the minority. Most kill their prey through other means. The pythons and boas, for example, squeeze their prey to death, constricting them in powerful coils until they can no longer breathe. But that doesn't mean they lack venom.

The Venom' glands of these constrictors mostly produce lubricating mucus, which helps the snakes to swallow prey easily. But Bryan Fry from the University of Queensland has found that the glands still produce small amounts of venom proteins. So do the equivalent glands of iguanian lizards—the group that includes iguanas, anoles and chameleons. These snakes and lizards are unlikely to be using their venom to subdue prey or to defend themselves, but they clearly still make the stuff. Their toxins are the equivalent of a kiwi's wing or the sightless eyes of blind cavefish— defunct remnants of a functional past. This is not the first time that Fry has shaken our understanding of animal toxins. In 2009, he showed that the Komodo dragon kills its prey with venom, rather than blood poisoning caused by a filthy bacteria-laden bite. And earlier, in 2006, he showed that venom is a far older and broader reptile invention than anyone had guessed. Until then, everyone thought that there were only two venomous lizards—the Gila monster and the Mexican beaded lizard—which evolved their toxins independently from the hundreds of venomous snakes. Fry showed

otherwise. While capturing monitor lizards in the field, he noticed that they had bulges in their heads at the same place as the Gila monster's venom glands. "It was a Captain Obvious moment," he says. Fry eventually isolated venom proteins from many supposedly non-venomous species of lizard and snake, including all monitors and frequently kept pets like bearded dragons and ratsnakes. He argued that reptile venom evolved only once, in the common ancestor of this reptile group, which he called Toxicofera. It covers all snakes and a significant proportion of all lizards. The Toxicoferan ancestor had two pairs of venom glands, one in the upper jaw and one in the lower, which secreted an already complicated set of venom proteins. Its descendents duplicated the genes that produced these proteins, and tweaked them to produce even more chemical weapons. They also streamlined their venom glands—some venomous lizards, like the monitors and Gila monster, lost the top pair, while the snakes downplayed the bottom set. Fry's new study is a sequel to this classic work. He took a much closer look at the venom glands of several constrictors like pythons and boas, and iguanians like the veiled chameleon and the common iguana. He dissected them, stuck them in medical scanners, catalogued their proteins, and more. For a start, he doubled the number of known venom glands. He studied the red-tailed pipe snake—a member of one of the most ancient of snake lineages—and found that it secreted venom from four glands at the corners of its mouth called rictal glands. These structures had been completely ignored since the 1920s, but Fry showed that they produce venom. His also found venom proteins in the constricting pythons and boas, and in iguanians. The levels are too low to be used as a defence or to kill

prey [although the more predatory iguanians did have more proteinsecreting cells in these glands—maybe a killing role isn't out of the question). "Nothing in evolution is every really lost," Fry says. Even if venom glands have been repurposed for making mucus, you'd expect them to still produce traces of venom. Nicholas Casewell from Liverpool School of Tropical Medicine, who studies venom evolution, says that the study addresses unanswered questions from Fry's earlier work, which "has been contentious". For example, the fact that the boas and pythons have tiny amounts of venom fits with the idea that they evolved from venomous ancestors and have since downplayed their toxic heritage. Casewell adds that the new study helps to answer another baffling question: "Why would a vegetarian iguanid require the secretion of venom toxins?" In the iguanians, the most common of the venom proteins—crotamine and crystatin—originally evolved as defences against microbes. Fry thinks that reptile venom actually has its origins in killing microbes rather than prey. The common ancestor of the venomous snakes and lizards had

glands that churned out proteins that kept bacteria at bay. By tweaking these proteins to kill other animals instead, and ramping up their manufacture, these early reptiles turned their chemical shields into swords. Indeed, some of the iguanian and constrictor venom proteins are still evolving, and rapidly so in some cases. Perhaps they

Turtle Genome Analysis Sheds Light On Turtle Ancestry and Shell Evolution Sciencedaily.com— From which ancestors have turtles evolved? How did they get their shell? New data provided by the Joint International Turtle Genome Consortium, led by researchers from RIKEN in Japan,

BGI in China, and the Wellcome Trust Sanger Institute in the UK provides evidence that turtles are not primitive reptiles but belong to a sister group of birds and crocodiles. The work also sheds light on the evolution of the turtle's intriguing morphology and reveals that the turtle's shell evolved by recruiting genetic information encoding for the limbs. Turtles are often described as evolutionary monsters, with a unique body plan and a shell that is considered to be one of the most intriguing structures in the animal kingdom. "Turtles are interesting because they offer an exceptional case to understand the big evolutionary changes that occurred in vertebrate history," explains Dr. Naoki Irie, from the RIKEN Center for Developmental Biology, who led the study. Using next-generation DNA sequencers, the researchers from 9 international institutions have decoded the genome of the green sea turtle and Chinese softshell turtle and studied the expression of genetic information in the developing turtle. Their results published in Nature Genetics show that turtles are not primitive reptiles as previously thought, but are related to the group

comprising birds and crocodilians, which also includes extinct dinosaurs. Based on genomic information, the researchers predict that turtles must have split from this group around 250 million years ago, during one of the largest extinction events ever to take place on this planet. "We expect that this research will motivate further work to elucidate the possible causal connection between these events," says Dr. Irie. The study also reveals that despite their unique anatomy, turtles follow the basic embryonic pattern during development. Rather than developing directly into a turtle-specific body shape with a shell, they first establish the vertebrates' basic body plan

and then enter a turtle-specific development phase. During this late specialization phase, the group found traces of limb-related gene expression in the embryonic shell, which indicates that the turtle shell evolved by recruiting part of the genetic program used for the limbs. "The work not only provides insight into how turtles evolved, but also gives hints as to how the vertebrate developmental programs can be changed to produce major evolutionary novelties." explains Dr. Irie. Another unexpected finding of the study was that turtles possess a large number of olfactory receptors and must therefore have the ability to smell a wide variety of substances.

Reptile of the Month! Species : Uromastix Diet: Greens and Lagums Sex: Male Level: Medium Age : Two years Has been with us : five month Health : appears healthy Status : Adoptable Tiger is a very sweet shy guy. He would never harm you but will run away and hide. He tolerates being held. I don't know his real history, but he was the pet of a child for a year and a half with iffy care. Thankfully he was given to a reptile lover who did her best with him, decided she was not equipped to care properly for him and he came to us. He likes it HOT! with lots UVB. He was eating, coming out and sunning himself after several weeks, but since I moved him a couple of weeks ago, he just hides. He has a discolored belly so I think he was burned in the past. He eats a mix of f/t legumes, greens and bird seed.

Society News We had two great meeting. April meeting dealt with crested ^geckos and others Rhacodactylus species and was fantastic and informative. A nice young lady won Angle and a bunch of new people came. We had a last minute meeting with Eric Loza, a longtime member that moved away many years ago. He spoke about his trip to Africa. Not a lot of reptiles, but WOW the cool animals! He is a fantastic story teller ON

Sadly after being outside for who knows how long, and in a box for three days when the lady who found it, then tried to find his home, even after a vet trip and lots of loving care, he passed. So please get help if you need it. And I curse the owner if they just let the chameleon go instead of finding it a new and proper V\ L . (
