  • Cyclura Or Rock Iguanas Cyclura Spp
    Cyclura or Rock Iguanas Cyclura spp. There are 8 species and 16 subspecies of Cyclura that are thought to exist today. All Cyclura species are endangered and are listed as CITES (Convention on International Trade in Endangered Species) Appendix I, the highest level of pro- tection the Convention gives. Wild Cyclura are only found in the Caribbean, with many subspecies endemic to only one particular island in the West Indies. Cyclura mature and grow slowly compared to other lizards in the family Iguani- dae, and have a very long life span (sometimes reaches ages of 50+ years). The more common species in the pet trade in- clude the Rhinoceros Iguana (Cyclura cornuta cornuta), and Cuban Rock Iguana (juvenile), the Cuban Rock Iguana (Cyclura nubila nubila). Cyclura nubila nubila Basic Care: Habitat: Cyclura care is similar to that of the Green Iguana (Iguana iguana), but there are some major differences. Cyclura Iguanas are generally ground-dwelling lizards, and require a very large cage with lots of floor space. The suggested minimum space to keep one or two adult Cyclura in captivity is usually a cage that is at the very least 10’X10’. Because of this space requirement, many cyclura owners choose to simply des- ignate a room of their home to free-roaming. If a male/female pair are to be kept to- gether, multiple basking spots, feeding stations, and hides will be required. All Cyclura are extremely territorial and can inflict serious injuries or even death to their cage- mates unless monitored carefully. The recommended temperature for Cyclura is a basking spot of about 95-100F during the day, with a temperature gradient of cooler areas to escape the heat.

This may include breeding or territorial animals. POTENTIAL PHYSICAL HAZARDS: Bites, scratches, tail-whips: Rhinoceros Iguanas will defend themselves when threatened using bites, scratches and whipping with the tail. Generally innocuous, however, bites from adults can be severe resulting in deep lacerations. RISK MANAGEMENT: To reduce the risk of injury from these lizards the following steps should be followed: - Keep animal away from face and eyes at all times - Use of correct PPE such as thick gloves and employing correct and safe handling techniques when close contact is required. Conditioning animals to handling is also generally beneficial. - Collection Management; If breeding is not desired institutions can house all female or all male groups to reduce aggression - If aggressive animals are maintained protective instrument such as a broom can be used to deflect an attack OTHER HAZARDS: Zoonosis: Rhinoceros Iguanas can potentially carry the bacteria Salmonella on the surface of the skin. It can be passed to humans through contact with infected faeces or from scratches. Infection is most likely to occur when cleaning the enclosure. RISK MANAGEMENT: To reduce the risk of infection from these lizards the following steps should be followed: - ALWAYS wash hands with an antiseptic solution and maintain the highest standards of hygiene - It is also advisable that Tetanus vaccination is up to date in the event of a severe bite or scratch Husbandry Guidelines: C.

  • TERRESTRIAL SPECIES Grand Cayman Blue Iguana Cyclura Lewisi Taxonomy and Range the Grand Cayman Blue Iguana, Cyclura Lewisi, Is
    TERRESTRIAL SPECIES Grand Cayman Blue iguana Cyclura lewisi Taxonomy and Range Kingdom: Animalia, Phylum: Chordata, Class: Sauropsida, Order: Squamata, Family: Iguanidae Genus: Cyclura, Species: lewisi The Grand Cayman Blue iguana, Cyclura lewisi, is endemic to the island of Grand Cayman. Closest relatives are Cyclura nubila (Cuba), and Cyclura cychlura (Bahamas); all three having apparently diverged from a common ancestor some three million years ago. Status Distribution: Species endemic to Grand Cayman. Conservation: Critically endangered (IUCN Red List). In 2002 surveys indicated a wild population of 10-25 individuals. By 2005 any young being born into the unmanaged wild population were not surviving to breeding age, making the population functionally extinct. Cyclura lewisi is now the most endangered iguana on Earth. Legal: The Grand Cayman Blue iguana Cyclura lewisi is protected under the Animals Law (1976). Pending legislation, it would be protected under the National Conservation Law (Schedule I). The Department of Environment is the lead body for legal protection. The Blue Iguana Recovery Programme BIRP operates under an exemption to the Animals Law, granted to the National Trust for the Cayman Islands. Natural history While it is likely that the original population included many animals living in coastal shrubland environments, the Blue iguana now only occurs inland, in natural dry shrubland, and along the margins of dry forest. Adults are primarily terrestrial, occupying rock holes and low tree cavities. Younger individuals tend to be more arboreal. Like all Cyclura species the Blue iguana is primarily herbivorous, consuming leaves, flowers and fruits. This diet is very rarely supplemented with insect larvae, crabs, slugs, dead birds and fungi.

  • Cyclura Cychlura) in the Exuma Islands, with a Dietary Review of Rock Iguanas (Genus Cyclura)
    Herpetological Conservation and Biology 11(Monograph 6):121–138. Submitted: 15 September 2014; Accepted: 12 November 2015; Published: 12 June 2016. FOOD HABITS OF NORTHERN BAHAMIAN ROCK IGUANAS (CYCLURA CYCHLURA) IN THE EXUMA ISLANDS, WITH A DIETARY REVIEW OF ROCK IGUANAS (GENUS CYCLURA) KIRSTEN N. HINES 3109 Grand Ave #619, Coconut Grove, Florida 33133, USA e-mail: [email protected] Abstract.—This study examined the natural diet of Northern Bahamian Rock Iguanas (Cyclura cychlura) in the Exuma Islands. The diet of Cyclura cychlura in the Exumas, based on fecal samples (scat), encompassed 74 food items, mainly plants but also animal matter, algae, soil, and rocks. This diet can be characterized overall as diverse. However, within this otherwise broad diet, only nine plant species occurred in more than 5% of the samples, indicating that the iguanas concentrate feeding on a relatively narrow core diet. These nine core foods were widely represented in the samples across years, seasons, and islands. A greater variety of plants were consumed in the dry season than in the wet season. There were significant differences in parts of plants eaten in dry season versus wet season for six of the nine core plants. Animal matter occurred in nearly 7% of samples. Supported by observations of active hunting, this result suggests that consumption of animal matter may be more important than previously appreciated. A synthesis of published information on food habits suggests that these results apply generally to all extant Cyclura species, although differing in composition of core and overall diets. Key Words.—Bahamas; Caribbean; carnivory; diet; herbivory; predation; West Indian Rock Iguanas INTRODUCTION versus food eaten in unaffected areas on the same island, finding differences in both diet and behavior (Hines Northern Bahamian Rock Iguanas (Cyclura cychlura) 2011).

  • A Survey of the Nutrient Content of Foods Consumed by Free Ranging and Captive Anegada Iguanas (Cyclura Pinguis)
    A SURVEY OF THE NUTRIENT CONTENT OF FOODS CONSUMED BY FREE RANGING AND CAPTIVE ANEGADA IGUANAS (CYCLURA PINGUIS) Ann M. Ward, MS,1* Janet L. Dempsey, MS,, and Amy S. Hunt, MS1 1Nutritional Services Department, Fort Worth Zoo, Fort Worth, Texas; 2Animal Nutrition Department, Saint Louis Zoo, Saint Louis, Missouri Abstract Nutrient concentrations were determined in foods consumed by both free ranging and captive Anegada iguanas (Cyclura pinguis). Twenty-two species of plants, known to be consumed by free ranging iguanas during the dry season, were collected and analyzed. The plant parts were separated and categorized for analysis as flowers, fruits, or leaves. Mean nutrient concentrations and standard errors (SEM), on a dry matter basis (DMB), included protein (CP) 9.61% ± 0.84, acid detergent fiber (ADF) 29.17% ± 2.29, neutral detergent fiber (NDF) 37.48% ± 3.06, and crude fat (FAT) 4.87% ± 0.81. Nutrient concentrations were analyzed in diets offered and consumed by captive iguanas held for re-introduction at a headstart facility on Anegada, British Virgin Islands. Captive diets were comprised of mixed greens (cabbage, romaine), natural leaves (buttonwood and parrotwood), fruits (banana, honeydew melon), vegetables (red pepper, carrot, cucumber, mushroom), and a commercial complete feed (Zoo Med Juvenile Iguana Diet). Diets consumed by hatchlings and juveniles were 17.36 – 21.97% CP, 18.24 – 34.95% ADF, 18.57 – 36.08% NDF, and 2.11 – 4.36% FAT. All captive Anegada iguanas consumed higher protein levels than those levels available in plants during the dry season. These captive consumption levels were similar to those consumed by headstarted Jamaican iguanas (Cyclura collei), as well as levels in plants collected during the dry season in Jamaica.

Female movements while seeking a nesting site ranged from 0.3 to 12.8 km, were mostly erratic. Time elapsed between mating and oviposition averaged 30 ± 5 days, while the nesting period lasted four weeks (July to early August). Nest site fidelity by females in consecutive years was 50%, although non-resident females at one study site used the same beach 72% of the time. Clutch size averaged 14 eggs and was positively correlated with female snout-vent length (SVL). Egg length was the only egg size variable correlated negatively with female size. Incubation temperatures averaged 32.8° C (2005) and 30.2° C (2006) and fluctuated up to 9° C. Overall hatching success from 2003–2005 was 75.9%. Some nests failed as a result of flooding of the nest chamber and in one case a nest was destroyed by feral pigs.
