Ethoecological Observations of Ctenosaura similis (Sauria: Iguanidae) in British Honduras Robert W. Henderson Museum of Natural History, University of Kansas, Lawrence, Kansas 66044 ABSTRACT-A small population of Ctenosaura similis was studied in Belize, British Honduras. Black spiny-tailed iguana were introduced to the United States through intentionally released or escaped pets in the 1970s. Key Words.—bakeri; Ctenosaura; endangered; growth; Iguana; size; Spiny-tailed; Utila INTRODUCTION Utila Spiny-tailed Iguanas, Ctenosaura bakeri (Stejneger 1901), are endemic to the island of Utila (de Queiroz 1987), the most westerly of the Bay Islands, located off the Caribbean versant of Honduras (McCranie et al. Despite the high visibili- The ADW Team gratefully acknowledges their support. The species range in size (total length, including the tail) from about 12.5 centimetres (4.9 in) to well over 1 metre (39 in). Ctenosaura similis is found throughout Mexico, large areas in Central America, and islands adjacent to Panama (Halliday and Adler 1992). In Colombia, first museum collections occurred in before 1933 (Barbour and Shreve, 1934); but introductions by humans to these islands likely occurred many years prior (Dunn, 1945; Rueda-Almonacid, 1999; Forero-Medina et al., 2006). Regardless, C. similis is a dietary opportunist and will eat whatever it can catch.

In this study, we employed RT-PCR to amplify the amelogenin gene from the black spiny-tailed iguana Ctenosaura similis teeth, and discovered a novel splicing form of the amelogenin gene. Despite their size, they appear to be quite agile; it was not unusual to see the large black spiny-tail iguanas (Ctenosaura similis) high up in trees. There is considerable variation with age and sex and therefore identification may be difficult. In some areas, eating their flesh is considered potent "medicine", with the person deriving the iguana's strength after eating it. Black Iguana (Ctenosaura similis) Photo no. Taxon Information Deliberate releases have occurred on Keeywadin Island, and likely have occurred on Cayo Costa and other islands as well (Krysko et al., 2003). Your Ctenosaura Similis stock images are ready. Fire and grazing are important in the long-term maintenance of grasslands. Most have black mottling on their backs.

Trappers dispatched captured lizards with a pistol load­ed with birdshot or .22 caliber bullets. ©Simon Pierre Barrette-2016/via wikipedia - CC BY-SA 4.0. Life Cycle Adult C. similis can reach lengths of 4 ft and are predominately black in color. This seems particularly true in Florida, USA, and Venezuela where populations are still manageable and eradication/extirpation is possible with dedicated, persistent management efforts. In breeding season, the oviparous females then migrate to suitable areas to nest. Family: Iguanidae. (Murphy 1989; Roberts and Roberts 1993). IUCN Red List Status: Least Concern. The Black Spiny-tailed Iguana or Black Iguana or Black Ctenosaur, is a lizard native to Mexico and Central America that has been introduced to the United States in the state of Florida. The ecological impact of man on the South Florida herpetofauna. According to the Iguana Taxonomy Working Group (2011), “A well-resolved phylogenetic hypothesis of all taxa in this genus is sorely needed.”. Black spiny-tailed iguana have distinctive black, keeled scales on their long tails, which gives them their common name. Encyclopedia of Reptiles & Amphibians: A Comprehensive Illustrated Guide. In par­ticular, mean minimum monthly temperatures in Managua, Nicaragua during winter (December to February) range from 19.7-21.2 °C, whereas on Gasparilla Island during the same months mean monthly temperatures range from 10.9-12.8 °C. Rueda-Almonacid JV, 1999. In the introduced population on Gasparilla Island in Florida, USA, testes size peaked mark­edly during January to April, after which there was rapid tes­ticular regression (Avery et al., 2014). Trying to brush my sadness away, I open the cage sitting on the chest of drawers in my living room. The Gasparilla Island population possibly originated from three animals kept as pets and then released around 1979 (Krysko et al., 2003). "Ctenosaura similis" (On-line), Animal Diversity Web. (Ervin 1992). Ctenosaura similis is native from southern Mexico to Central America. Clutch size varies with species, size and age of the female. A terrestrial biome. Since 2008, Florida residents in areas beset by populations of C. similis have self-imposed taxes totalling in excess of $250,000 to hire professional trappers to control these invasive animals. forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality. Ctenosaura similis, commonly known as black spiny-tailed iguana, is the largest and most widely distributed ctenosaur. Adapts well to disturbed areas, parkland, and human habitation (Henderson, 1973; González-García et al., 2009). Genetic analyses of C. similis in Florida, USA, revealed a set of 5 haplotypes (Nuñez, 2016). Krysko KL; Larson KW; Diep D; Abellana E; McKercher ER, 2009. The rate or frequency of such events is unknown, but even a single introduction event can potentially produce serious long-term consequences. Possible methods for controlling C. similis using chemical toxicants were investigated. Geographic distribution: Ctenosaura similis (Gray's spiny-tailed iguana).

Moira, a Ctenosaura similis iguana. One male in the colony is dominant, and although the other males hold territories, they will only defend them against one another and not against the leader. Man and his domestic animals are inevitably destroying the iguanas' environments and their species. Ctenosaurs were most abundant in areas disturbed by man. Natural history of the black spiny-tailed iguana (Ctenosaura similis) at Parque Nacional Palo Verde, Costa Rica, with comments on the conservation of the genus Ctenosaura. Economic impacts are localized and consist principally of damage to ornamental plants used as landscaping at private residences and community buildings. 2005). The Florida population is subjected to a very different tem­perature regime than native C. similis. In Florida, USA, clutch size averaged 32 (n = 56), with a range of 6-62 (Avery et al., 2014). Ctenosaurs have been intentionally transported from their native range to offshore Caribbean islands (Dunn, 1945; Rueda-Almonacid, 1999; Forero-Medina et al., 2006) and to Florida, USA (Krysko et al., 2003). A small bone bows out to extend the dewlap during times of threat, courtship, or while defending territory. The iguanas' reaction to the cries is to "freeze" and they are then easily caught (Murphy 1989). It occurs in Mexico and throughout much of Central America (The Reptile Database, 2016). Females lack obvious crests. Zootaxa, 3028:1-64. Increased biosecurity measures to detect and remove ctenosaurs potentially hitch-hiking on cargo ships would help prevent accidental introductions such as recently occurred in Venezuela (Barrio-Amorós and Rivas-Fuenmayor, 2008). ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe.

Black Iguana (Ctenosaura similis) Photo no. They have even been noted to eat eggs of their own young, and in one case, the tail of a juvenile was found inside an adult male, suggesting cannibalism. Ctenosaura similis, Tulum, Mexico. Phylogeography and hybridization in Ctenosaura species (Sauria, Iguanidae) from Caribbean Honduras: insights from mitochondrial and nuclear DNA. Townsend JH, Krysko KL, Enge KM, 2003. Caldasia, 3(14):363-365. Other burrow- or ground-nesting species of concern, such as the Florida burrowing owl (Athene cunicularia floridana), a species of Special State Concern in Florida, and the federally threatened least tern (Sterna antillarum), are potentially vulnerable to predation, although direct impacts to these species remain to be documented (Krysko et al., 2003). (Situacion actual y problematica generada por la introduccion de "rana toro" a Colombia.) The spines down the back are short. Krysko KL; King FW; Enge KM; Reppas AT, 2003. Jual … Distribution of the introduced black spiny-tailed iguana (Ctenosaura similis) on the southwestern coast of Florida. Portrait of male black spiny-tailed iguana (Ctenosaura similis). CABI, Undated. The recent appearance of ctenosaurs in Venezuela (Barrio-Amorós and Rivas-Fuenmayor, 2008; Flores and Esqueda, 2008), presumably through hitchhiking on ships, demonstrates the on-going potential for the species to spread to new areas. The lizards have tails ringed with rows of sharp, curved spines, hence the name spiny-tailed iguana. Male iguanas possess a pair of intromittent organs, the hemipenes. The distribution in this summary table is based on all the information available. by Powell R, Henderson RW]. Iguana Taxonomy Working Group, 2011. Total imports of C. similis to the US peaked in 2004 (3296 animals), but decreased to 76 by 2008 (Stephen et al., 2011). Herpetological Review, 37(4):494. Clutch size with­in size classes did not differ from that recorded in Nicaragua (Fitch and Hen­derson, 1978). Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. Trappers employed com­mercial live traps with 2.54 × 2.54 cm or 1.27 × 2.54 cm mesh and baited with fresh cantaloupe or watermelon. Island Press. It is clear that ctenosaurs can disperse short distances on land, and C. similis is capable of swimming. They are green as babies, and develop stunning coloration and patterning as they mature. It is often found in close proximity to human activity. Ctenosaura similis, commonly known as black spiny-tailed iguana, is the largest and most widely distributed ctenosaur.Its native range stretches from southern Mexico to Panama where is exploited for food and traditional medicine. Fitch HS; Henderson RW, 1978. Ctenosaurs have eaten rodents, bats, frogs, small birds, and a variety of insects. C. similis on Gasparilla Island, Florida (USA) negatively impacts state threatened gopher tortoises (Gopherus polyphemus) through direct predation (Avery et al., 2009), occupation of tortoise burrows (Engeman et al., 2009), and utiliza­tion of food resources (Krysko et al., 2009). Butterfield BP, Meshaka Jr WE, Guyer C, 1997. The capacity of C. similis to co-exist in altered environments coupled with its high fecundity has contributed to its successful establishment and spread in Florida, USA, where it consumes valuable horticultural plants, invades dwellings, and threatens imperilled native species through predation and usurpation of burrows. Molecular analyses of three non-indigenous squamate species in Florida: testing hypotheses of introduction pathways, species identity, and native range origins. Ithaca, New York: Society for the Study of Amphibians and Reptiles Contributions to Herpetology, 95-128. In Collier County a private landowner released between 5-30 lizards on his property on the southern end of the Keewaydin Island in 1995 (Krysko et al., 2003). Captive Lifespan: More than 20 Years. The very concentrated breeding season (February to April) characteristic of the species in its na­tive range (Nicaragua; Fitch and Henderson, 1978) oc­curs 2 months later (April to June) in the introduced range (Florida; Avery et al., 2014). No estimate of direct economic loss is available. During April to June, 81% (199 of 245) of females of reproductive size (>185 mm snout-vent length, SVL), possessed either oviducal eggs, vitellogenic folli­cles, or a convoluted oviduct indicating previous laying. There is no evidence of multiple clutches per year. There are currently at least five species of established large lizards in Florida: Green Iguana (Iguana iguana, Figure 28-2), Black Spiny-tailed Iguana (Ctenosaura similis, Figure 28-3), Mexican Black Spiny-tailed Iguana (Ctenosaura pectinata), Nile Monitor (Varanus niloticus, Figure 28-4), and Argentine Tegu (Tupinambis merianae).
