Herpetological Conservation and Biology 7(3):391–398. Ctenosaura bakeri (Utila Spiny-tailed Iguana). Thousands of new, high-quality pictures added every day. Ctenosaura bakeri is distinguished from similar species based on scutellation of the tail, dewlap size, and dorsal crest coloration (Bailey 1928; de Queiroz 1987, 1990). [7] This dorsal crest consists of white and black spines arranged in alternating groups of two or three of the same color. From Wikimedia Commons, the free media repository. Ctenosaura defensor Is the smallest in size in the genus Ctenosaura, but also the most colorful, with very variable color combinations: normally, the head and base of the tail have a gray color that during firing up times changes in A very light blue, the front back has streaks more or less uniform (sometimes stained spots) of a black pitch. [7], Ctenosaura bakeri was first described by Norwegian-born American zoologist Leonhard Stejneger in 1901, while working for the Smithsonian Institution. [2] Unique among iguanids and rare among reptiles, it is believed that C. bakeri was pushed into the mangrove swamps due to competition from the larger, more aggressive C. similis, which typically inhabits the drier habitats on Utila. [2] The iguana is locally hunted for meat, although efforts to educate locals have helped reduce this somewhat in recent years. 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. Summary . [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. [6] As a result, the Iguana Research and Breeding Station was built in April 1997 with the help and funds of various organizations such as the Frankfurt Zoological Society, the Senckenberg Nature Research Society, AFE-COHDEFOR (State Forestry Administration-Honduran Forestry Development Corporation), BICA (Bay Islands Conservation Association) and the National Autonomous University of Honduras. 98 0 obj <>stream Other members of the genus have a green or yellow coloring when young and turn darker with age.

Fig. [6][7] The population is currently stable, but future declines are expected as a result of the threats mentioned above. It has been observed that the di erent mangrove species are preferred by di erent age classes: hatchlings prefer the red mangroves, juveniles the black ones, while adults the white ones ([31], [8]).

Your Ctenosaura Bakeri stock images are ready. [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. Herpetological Conservation and Biology. The distinctive feature of this genus is the presence of enlarged, spiny scales on the tail. The total range of C. bakeri comprised about 1,091 ha of mangrove swamp. 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).

Distribution and habitat utilization of Ctenosaura bakeri on Utila. Access to Utila may have involved over-water dispersal during hurricanes, as is known for Iguana iguana in the Lesser Antilles or a land bridge to the mainland lost during the close of the last ice age. [6] Although several zoos and wildlife associations have instituted programs for the iguanas on Utila, the species still finds itself threatened due to overhunting and may face more of a threat in the form of habitat loss. The Utila spiny-tailed iguana feeds on plant matter and small invertebrates that inhabit the mangroves (2). [4], The hatchlings are 15 centimeters (5.9 in) long, the body length being a mere 3 centimeters (1.2 in) with the tail accounting for 12 centimeters (4.7 in) of its total length. ... enclosure size around 200 x 150 x 200 cm for a pair.
