[7] Its specific name, bakeri, is the Latinized form of Stejneger's friend and colleague Frank Baker, who was a former director of the National Zoo in Washington, D.C..[6], The species is believed to have evolved from mainland-based ancestors, and may share ancestors with C. melanosterna and C. palearis, as it is phylogenetically closer to these two than it is to C. similis. (Check it out on Researchgate!) [3], Like most iguanids, Ctenosaura bakeri is primarily herbivorous, eating flowers, leaves, stems, and fruit, but they will opportunistically eat smaller animals, eggs, and arthropods that inhabit the mangroves. 2005. �Y���eE}

Total population size is not known, but it is estimated that there may be fewer than 2,500 mature individuals. Larger species, such as the black spiny-tailed iguana: 6 feet long by 24 inches wide by 30 inches tall. It is one of only two known species of lizard, the other being a species of anole, Anolis utilensis, that lives solely in mangrove forests. 1) is endemic to the island of Utila, Honduras. This species occupies a portion of Utila, a small continental island located off the northern coast of Honduras, in the Bay Islands chain. [6] The International Iguana Society and the CPUI have sought to purchase land to preserve habitats for the iguanas and plan to establish an outpost manned by Iguana Research and Breeding station personnel, who will aid in monitoring the property and work with developers to select building sites that preserve as much undisturbed beach area as possible.

Ctenosaura bakeri, also known as the Utila iguana, Baker's spinytail iguana, swamper or wishiwilly del suampo, is a critically endangered species of spinytail iguana endemic to the island of Utila, one of the Islas de la Bahía off the coast of Honduras. [2][7] It has been observed eating smaller green iguanas (Iguana iguana) and geckos such as Hemidactylus frenatus. In the case of the Utila iguana, 50% of the animals hatched at the Center are maintained for the head-start program and the rest are released into mangrove forests after hatching.

The Utila spiny-tailed iguana feeds on plant matter and small invertebrates that inhabit the mangroves (2). The other six species belong to the genus Ctenosaura and are grouped as black iguanas, although the color does not predominate in all iguanas. Our results suggest on-togenetic size-related shifts of habitat use in this species.

[5] Males may grow up to 76 centimeters (30 in) in length, while females are smaller, with a length of up to 56 centimeters (22 in). Aims: To estimate the population size of Roatán spiny-tailed iguanas (Ctenosaura oedirhina) on the island of Roatán, Honduras. View/ Open. Structured data. [3] It is the smallest of the three species of iguana found on Utila, and unique among spiny-tailed iguanas as it is born a dark color as opposed to bright green or yellow. Tijdens de CITES CoP15 werden de voorstellen van Guatemala en Honduras om 4 Ctenosaura soorten op CITES Appendix II te plaatsen aangenomen. [3][7], Males achieve a maximum total length (including tail) of 76 centimeters (30 in), while females are typically 30% smaller at 56 centimeters (22 in) total length. [3], Gunther Köhler found the species at the brink of extinction, perhaps even functionally extinct in the wild as of 1994 due to overhunting and its restricted habitat. This is a male San Esteban Island … [10], This species currently has an estimated wild population of 10,000 animals in 2–3 subpopulations, but is greatly threatened by loss of habitat,[6] as mangrove forests are being used as garbage dump sites and deforested for the construction of homes, resorts, and marinas. 98 0 obj

Ctenosaura bakm' is distinguished from C. acanthura, C. hemilopha, C. pectinata, and C. similis by enlarged, strongly keeled scales on the proximal anterodorsal surface of the shank and a smaller maximum size (<250 mm vs. >300 mm SVL). [4] As the Utila iguana cannot successfully lay its eggs in the mangrove swamps, the gravid females are forced to migrate to nearby sandy beaches in order to bury their clutches of eggs so they can incubate in the hot sun. h�b```f``�g`a`Pad@ A�+P���EA%"���s�5�K{�����X&��fU=Ǭ+�=t�e�����,�jV]a�����`��������Ѡ����%��,��47���a`�`Na^Ƣò�%���*���.\@�Ӻm�.1�0iC\���^���������!|F � ɬ1,

We studied the habitat use in the Utila iguana (Ctenosaura bakeri Stejneger, 1901) in a heterogeneous mangrove forest site on the north coast on Utila Island using 162 sightings of iguanas along a line-transect. Here, for the first time, we present a comprehensive mapping of its overall distribution and nesting area. Captions.

While mangrove habitat is perfect habitat for feeding and resting, it is not ideal for nesting, and so when the time comes, female Utila spiny-tailed iguanas migrate to the island's beaches, where they lay their eggs in the sand and leave them to be incubated by the sun (4). Summary . Here, for the first time, we present a comprehensive mapping of its overall distribution and nesting area. . 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. All the Ctenosaura (except the bakeri) present at birth an intense green color that could be mistaken with a green iguana.
