New Species of Choleoeimeria (Apicomplexa: Eimeriidae) from The
FOLIA PARASITOLOGICA 53: 91–97, 2006 New species of Choleoeimeria (Apicomplexa: Eimeriidae) from the veiled chameleon, Chamaeleo calyptratus (Sauria: Chamaeleonidae), with taxonomic revision of eimerian coccidia from chameleons Michal Sloboda1 and David Modrý1,2 1Department of Parasitology, University of Veterinary and Pharmaceutical Sciences Brno, Palackého 1–3, 612 42 Brno, Czech Republic; 2Institute of Parasitology, Academy of Sciences of the Czech Republic, Branišovská 31, 370 05 České Budějovice, Czech Republic Key words: Coccidia, Eimeriorina, Choleoeimeria, taxonomy Abstract. Coprological examination of 71 samples from a breeding colony of veiled chameleons, Chamaeleo calyptratus Duméril et Duméril, 1851, revealed a presence of two species of coccidia. In 100% of the samples examined, oocysts of Isospora jaracimrmani Modrý et Koudela, 1995 were detected. A new coccidian species, Choleoeimeria hirbayah sp. n., was discovered in 32.4% of samples from the colony. Its oocysts are tetrasporocystic, cylindrical, 28.3 (25–30) × 14.8 (13.5–17.5) µm, with smooth, bilayered, ~1 µm thick wall. Sporocysts are dizoic, ovoidal to ellipsoidal, 10.1 (9–11) × 6.9 (6–7.5) µm, sporocyst wall is composed of two plates joined by a meridional suture. Endogenous development is confined to the epithelium of the gall blad- der, with infected cells being typically displaced from the epithelium layer towards lumen. A taxonomic revision of tetrasporo- cystic coccidia in the Chamaeleonidae is provided.

COOPER, JR. I'* CHRISTOPHER S. DEPERNO I and JOHNNY ARNETT 2 ~Department of Biology Indiana University-Purdue University Fort Wayne Fort Wayne. bldiana 46805 2Department of Herpetology Cincinnati Zoo and Botanical Garden Cincinnati, Ohio 45220 (Received May 6, 1994; accepted June 27, 1994) Abstract--Experimental tests showed that poststrike elevation in tongue-flick- ing rate (PETF) and strike-induced chemosensory searching (SICS) in the gila monster last longer than reported for any other lizard. Based on analysis of numbers of tongue-flicks emitted in 5-rain intervals, significant PETF was detected in all intervals up to and including minutes 41~-5. Using 10-rain intervals, PETF lasted though minutes 46-55. Two of eight individuals con- tinued tongue-flicking throughout the 60 rain after biting prey, whereas all individuals ceased tongue-flicking in a control condition after minute 35. The apparent presence of PETF lasting at least an hour in some individuals sug- gests that there may be important individual differences in duration of PETF. PETF and/or SICS are present in all families of autarchoglossan lizards stud- ied except Cordylidae, the only family lacking lingually mediated prey chem- ical discrimination. However, its duration is known to be greater than 2-rain only in Helodermatidae and Varanidae, the living representatives of Vara- noidea_ That prolonged PETF and S1CS are typical of snakes provides another character supporting a possible a varanoid ancestry for Serpentes. -
2011: Alfaxalone Anesthesia in Veiled Chameleon
ALFAXALONE ANESTHESIA IN VEILED CHAMELEON, Chamaeleo calyptratus Zdenek Knotek, DVM, PhD,1,2* Anna Hrda, DVM,1 Nils Kley, DVM,2 Zora Knotkova, DVM, PhD1 1Avian and Exotic Animal Clinic, Faculty of Veterinary Medicine, University of Veterinary and Pharmaceutical Sciences Brno, 612 42 Brno, Czech Republic; 2Clinic for Avian, Reptile and Fish Medicine, University of Veterinary Medicine Vienna, 1210 Vienna, Austria ABSTRACT: After premedication by butorphanol (2 mg/kg) and meloxicam (1 mg/kg) alfaxalone (5 mg/kg IV) was administered to 30 adult veiled chameleons (Chamaeleo calyptratus). The induction time was 36.27 ± 19.83 s, a surgical plane of anesthesia was achieved after 2 minutes (121.67 ± 18.80 s) and lasted for 5 - 10 minutes. Full activity was restored 20.30 ± 5.10 minutes after the initial alfaxalone injection. Alfaxalone proved to be suitable form of short anesthesia in veiled chameleons. KEY WORDS: reptile anesthesia, lizards, sedation INTRODUCTION Alfaxalone (3-α-hydroxy-5-α-pregnane-11,20-dione) represents a veterinary alternative of drugs used for controlled sedation or anesthesia (Leece et al., 2009). To date, alfaxalone has been tested mainly in mammals where the administration of high doses can be associated with certain complications. Adverse effects of alfaxalone include temporary hypotension, while higher doses may result in prolonged apnea. Only a few clinical studies on the use of alfaxalone in reptiles have been published (Carmel, 2002; Simpson, 2004; Scheelings et al., 2010). These studies vary both in the amount of recommended dose and the description of clinical signs observed in reptiles. The aim of this project was to evaluate short-term intravenous anesthesia with alfaxalone in healthy veiled chameleons kept experimentally. -

Lizard Facts Lizards Are One of the Biggest, Most Diverse and Widespread Groups of Reptiles Found on Earth
Lizard Facts Lizards are one of the biggest, most diverse and widespread groups of reptiles found on Earth. They are found on all continents, except Antarctica. ▪ Lizard (suborder Sauria) refer to any of the more than 5,500 species of reptiles belonging in the order Squamata (which also includes snakes). They feature in a wide variety of colors, appearance, and size. ▪ It comprises 40 different families. According to the San Diego Zoo, there are currently over 4,675 lizard species, including iguanas, chameleons, geckos, Gila monsters, monitors, and skinks. Their ancestors appeared on Earth over 200 million years ago. ▪ Lizards are scaly-skinned reptiles that are usually distinguished from snakes by the possession of legs, movable eyelids, and external ear openings. However, some traditional (that is, non-snake) lizards lack one or more of these features. ▪ Due to their smooth and shiny appearance, some lizards can appear slimy or slippery. However, their skin – like all reptiles – is actually very dry due to a lack of pores to excrete water and oils. Class: Reptilia Higher classification: Scaled reptiles Kingdom: Animalia Order: Squamata Phylum: Chordata KIDSKONNECT.COM Lizard Facts MOBILITY All lizards are capable of swimming, and a few are quite comfortable in aquatic environments. Many are also good climbers and fast sprinters. Some can even run on two legs, such as the Collared Lizard and the Spiny-Tailed Iguana. LIZARDS AND HUMANS Most lizard species are harmless to humans. Only the very largest lizard species pose any threat of death. The chief impact of lizards on humans is positive, as they are the main predators of pest species. -
Vernacular Name GILA MONSTER
1/6 Vernacular Name GILA MONSTER GEOGRAPHIC RANGE Southwestern U.S. and northwestern Mexico. HABITAT Succulent desert and dry sub-tropical scrubland, hillsides, rocky slopes, arroyos and canyon bottoms (mainly those with streams). CONSERVATION STATUS IUCN: Near Threatened (2016). Population Trend: Decreasing. Threats: - illegal exploitation by commercial and private collectors. - habitat destruction due to urbanization and agricultural development. COOL FACTS Their common name “Gila” refers to the Gila River Basin in the southwest U.S. Their skin consists of many round, bony scales, a feature that was common among dinosaurs, but is unusual in today's reptiles. The Gila monster and the Mexican beaded lizard are the only lizards known to be venomous. Both live in North America. Gila monsters are the largest lizards native to the U.S. Gila monsters may bite and not let go, continuing to chew and, thereby, inject more venom into their victims. Venom is released from the venom glands (modified salivary glands) into the lower jaws and travels up grooves on the outside of the teeth and into the victims as the Gila monsters bite. The lizards lack the musculature to forcibly inject the venom; instead the venom is propelled from the gland to the tooth by chewing. Capillary action brings the venom out of the tooth and into the victim. Gila monsters have been observed to flip over while biting the victim, presumably to aid the flow of the venom into the wound. Bites are painful, but rarely fatal to humans in good health. While the bites can overpower predators and prey, they are rarely fatal to humans in good health although humans may suffer pain, edema, bleeding, nausea and vomiting. -

Snake venom is a crucial for survival. Some squamates, like iguanas, rely heavily poisonous “soup” of enzymes with harmful effects—including on vision to locate food, and use their pliable tongues to grab nervous system failure and tissue damage—that subdue prey. it. Other squamates, like snakes, evolved effective chemore- The venom also begins to break down the prey from the inside ception and use their smooth hard tongues to transfer before the snake starts to eat it. Venom is delivered through a molecular clues from the environment to sensory organs in wide array of teeth. -

JENKINS Abstract The unequal distribution of legal protections on endangered species has been attributed to the “charisma” and “cuteness” of protected species. However, the theory of kin selection, which predicts the genetic relationship between organisms is proportional to the amount of cooperation between them, offers an evolutionary explanation for this phenomenon. In this thesis, it was hypothesized if the unequal distribution of legal protections on endangered species is a result of kin selection, then the genetic similarity between a species and Homo sapiens is proportional to the legal protections on that species. -
Veiled Chameleon
Husbandry Guidelines for Veiled Chameleon Chamaeleo calyptratus (Reptilia: Chamaeleonidae) DUMÉRIL & DUMÉRIL 1851 Date By From Version 2015 Stuart Daniel WSI Richmond v 1 OCCUPATIONAL HEALTH AND SAFETY RISKS This species, veiled chameleon (Chamaeleo calyptratus), is classed as an innocuous animal and poses minimal to no risk to keepers. The veiled chameleon is a small, generally non-aggressive species which possesses no anatomical features that could cause any harm. Though it is common for individuals of this species to be reluctant toward handling, any action performed to avoid being handled is generally for display only and will not result in any physical aggression. Individuals that feel threatened will put on a threat display which involves an open mouth and extension of the throat pouch (see figure). On the odd occasion an individual may bite but it is very rare that this will break the skin or cause any discomfort at all. Working with any animal species poses a risk of zoonotic disease. Common zoonotic diseases are listed in the table below, as well as other potential hazards that may be present in the work environment. Potential hazards of working with veiled chameleons and in the work environment in general Physical Injury from manual handling Falls from ladders if enclosures are above head height Slips/trips over cluttered workspace or wet floor Chemical Injury or poisoning from misuse of chemicals -F10 veterinary disinfectant -Bleach -Medications Biological Zoonosis – Salmonella spp, Campylobacter spp, Klebsiella spp, Enterobacter -

Objectives for this inventory were to: 1) Inventory and document the occurrence of reptile and amphibian species occurring at DEVA, primarily within priority sampling areas, with the goal of documenting at least 90% of the species present; 2) document (through collection or museum specimen and literature review) one voucher specimen for each species identified; 3) provide a GIS-referenced list of sensitive species that are federally or state listed, rare, or worthy of special consideration that occur within priority sampling locations; 4) describe park-wide distribution of federally- or state-listed, rare, or special concern species; 5) enter all species data into the National Park Service NPSpecies database; and 6) provide all deliverables as outlined in the Mojave Network Biological Inventory Study Plan. Methods included daytime and nighttime visual encounter surveys, road driving, and pitfall trapping. Survey effort was concentrated in predetermined priority sampling areas, as well as in areas with a high potential for detecting undocumented species. -
Caring for Your Veiled Chameleon Scientific Name: Chameleo Calyptratus Native To: Yemen and Southern Saudi Arabia
caring for your Veiled Chameleon Scientific Name: Chameleo calyptratus Native to: Yemen and southern Saudi Arabia. Maximum Length: 6-12 inches long Life Span: Up to 5+ years with proper care characteristics: Veiled Chameleons are one of the most popular chameleon species in the reptile pet world. Veiled Chameleons are able to look in any direction without turning their heads or shifting their body because each eye can swivel nearly 180 degrees. Their eyes can also point in two different directions at the same time. Veiled Chameleons are sensitive animals and are not a pet that tolerates handling well. care tips: Enclosure: Provide a spacious screened enclosure for your Veiled Chameleon. An adult male needs more room to explore and should be housed in a cage that is 36 inches long by 36 inches wide by 48 inches tall. Females and young males can be kept in smaller enclosures. A longer enclosure will allow you to provide a warm end and a cooler end for your animal’s well-being. The more room you provide for your Veiled Chameleon the better. Do not house more than one chameleon together. Chameleons are very territorial and stress easily. Substrate: No specific substrate is needed but coconut fiber or potting soil with no added chemicals or perlit work well. Habitat: Provide branches and plants (live or fake) for the Veiled Chameleon to climb on. Create a dense area of non-toxic plants on one side for hiding and on the other side create a more open exposed area of branches for basking. Temperature and Lighting: Keep the enclosure 100° F on the warmer end and 70° F at the cool end.
