Cyclura carinata bartschi, commonly known as Bartsch's iguana or the Booby Cay iguana, is a subspecies of lizard in the family Iguanidae. The subspecies is endemic to a single cay, Booby Cay, in The Bahamas . [1]
Bartsch's iguana, Cyclura carinata bartschi, was first described by American herpetologist Doris M. Cochran in 1931. [2] It has some minor morphological characteristics which differ from the Turks and Caicos rock iguana, Cyclura carinata.
Its specific name, carinata, means "keeled" and refers to the animal's scalation. Its subspecific name, bartschi, was given in honor of Silesian-American zoologist Paul Bartsch. [3]
Further phylogenic study of mtDNA haplotypes by scientists at Utah Valley State College in 2007, determined that this animal should not be considered a valid subspecies merely upon population isolation and slight morphological differences, but rather that it is genetically, very similar to the Turks and Caicos rock iguana (Cyclura carinata) and that subspecies status should be revoked to include this population in conservation and intra-species breeding. [4] Morphological and genetic data indicate that the closest living relative of C. carinata is C. ricordi of Hispaniola. [5]
Measuring less than 770 mm (30 in) in total length (tail included) when full grown, Bartsch's iguana, like its parent species, the Turks and Caicos rock iguana, is one of the smaller species of Cyclura. [6] Bartsch's iguana is greenish to brownish-gray, with a yellow dorsal crest, faint yellow-brown reticulations on the bodies of the adults, and a golden iris. [7]
Like other members of the genus Cyclura, males of this species have larger femoral pores on their thighs, which are used to release pheromones. Females have smaller pores, making the animals sexually dimorphic. [8]
Bartsch's iguana is found only on Booby Cay in the Bahamas. [9] It is estimated that 1,000 of these iguanas live on this small cay and their population appears to be stable, despite the small number. [7] [9] It is rumored that this subspecies once lived on the larger island of Mayaguana and was referred to as the Mayaguana iguana. [2] [6]
Like all Cyclura species, Bartsch's iguana is primarily herbivorous, consuming leaves, flowers, and fruits from different plant species. [7] This diet is very rarely supplemented with insects, mollusks, crustaceans, arachnids, lizards, and carrion. [10]
The Bahamas National Trust has proposed to the Bahamas Government that Booby Cay, which also is a significant area for nesting seabirds, be protected under the national parks system. [7] A program to remove feral goats from the cay has also been initiated. [7] [9] It has been noted that "Australian pine" trees ( Casuarina equisetifolia ) introduced by man to the cay may pose a problem as the needles are inedible and their tall size prevents native plants, which Bartsch's iguana relies on for food, from growing. [9]
In 1998 a colony of Bartsch's iguana was established on Mayaguana. This population appears to be stable despite the presence of feral goats on the island. [11]
Mayaguana is the easternmost island and district of the Bahamas. Its population was 277 in the 2010 census. It has an area of about 280 km2 (110 sq mi).
The Turks and Caicos rock iguana is a species of lizard endemic to the Turks and Caicos islands. This small iguana can reach 30 in (76 cm) and becomes mature at seven years and may live for twenty. A single clutch of up to nine eggs is laid each year, and these take three months to hatch. This iguana is mostly herbivorous, but supplements this by adding some animal matter to its diet.
The blue iguana, also known as the Grand Cayman ground iguana, Grand Cayman blue iguana or Cayman Island rock iguana, is an endangered species of lizard which is endemic to the island of Grand Cayman. It was previously considered to be a subspecies of the Cuban iguana, Cyclura nubila, but in a 2004 article Frederic J. Burton reclassified it as a separate species because according to him the genetic differences discovered four years earlier between the different C. nubila populations warranted this interpretation. The blue iguana is one of the longest-living species of lizard.
The Mona ground iguana is a rock iguana that is endemic to Mona Island, Puerto Rico, and is the largest native terrestrial lizard in Puerto Rico. It was previously considered a subspecies of the rhinoceros iguana.
The rhinoceros iguana is an endangered species of iguana that is endemic to the Caribbean island of Hispaniola and its surrounding islands. A large lizard, they vary in length from 60 to 136 centimetres, and skin colours range from a steely grey to a dark green and even brown. Their name derives from the bony-plated pseudo-horn or outgrowth which resembles the horn of a rhinoceros on the iguana's snout.
The northern Bahamian rock iguana is a species of lizard of the genus Cyclura that is found on Andros Island and the Exuma islands in the Bahamas. Its status on the IUCN Red List is vulnerable, with a wild population of less than 5,000 animals.
The Cuban rock iguana, also known as the Cuban ground iguana or Cuban iguana, is a species of lizard of the iguana family. It is the second largest of the West Indian rock iguanas, one of the most endangered groups of lizards. A herbivorous species with a thick tail and spiked jowls, it is one of the largest lizards in the Caribbean.
Cyclura ricordii, also known as Ricord's ground iguana or Ricord's rock iguana, is an endangered species of medium-sized rock iguana, a large herbivorous lizard. It is endemic to the island of Hispaniola. It is known to coexist with the nominate subspecies of the rhinoceros iguana ; the two species are the only taxa of rock iguana to do so. The natural habitats of its three subpopulations are hot, dry, wooded savanna on limestone with access to soil and sandy flats in southern Hispaniola. It is threatened by predation by introduced predators and habitat loss, due to overgrazing and charcoal manufacture.
The Acklins ground iguana, also commonly known as the Watling Island iguana, is an endangered subspecies of lizard of the genus Cyclura it is one of three subspecific forms of Cyclura rileyi in the family Iguanidae.
Cyclura rileyi, commonly known as the Bahamian rock iguana or the San Salvador rock iguana, is a critically endangered species of lizard in the family Iguanidae. The species is native to three island groups in the Bahamas, and is in decline due to habitat encroachment by human development and predation by feral dogs and cats. There are three subspecies: the Acklins ground iguana, the White Cay iguana, and the nominotypical subspecies.
The Bahamian hutia or Ingraham's hutia is a species of hutia in the subfamily Capromyinae native to the Bahamas. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical dry shrubland, and rocky areas.
The Andros Island iguana or Andros iguana is an endangered subspecies of Northern Bahamian rock iguana of the genus Cyclura that is found on Andros Island on the western edge of Grand Bahama. Its status is Endangered, with a wild population of 3,500 animals, and it can be found on the IUCN Red List.
Cyclura nubila caymanensis, the Lesser Caymans iguana, Cayman Brac iguana, Cayman Island brown iguana or Sister Isles iguana, is a critically endangered subspecies of the Cuban iguana. It is native to two islands to the south of Cuba: Cayman Brac and Little Cayman, which are also known as the Sister Isles due to their similar shapes and close proximity to each other. The population of this subspecies has been impacted by habitat encroachment by human development and is likely being destroyed due to predation by cats, the population on Cayman Brac has remained particularly small for decades.
Cyclura cychlura inornata, the Allen Cays rock iguana or Allen Cays iguana, is a subspecies of the northern Bahamian rock iguana that is found on Allen's Cay and adjacent islands in the Bahamas. Its status in the IUCN Red List is critically endangered. The population has been growing over the last century. Although it was considered extinct in 1916, there are as of 2018 at least 482 mature adult animals counted on two islands, Leaf Cay and U Cay, and a few hundred on at least five other nearby islands where they have recently spread to by unknown means, as well as many juveniles.
Cyclura cychlura figginsi, known by the common name of guana and sometimes called the Exuma Island iguana in the international literature, is a subspecies of the northern rock iguana, C. cychlura, that is found on the Exuma island chain in the Bahamas with an estimated wild population of 1,300 animals in 2004, it has been listed on the IUCN Red List as critically endangered.
Cyclura rileyi cristata, the White Cay iguana or Sandy Cay rock iguana, is a critically endangered subspecies of lizard of the genus Cyclura native to a single cay in the Bahamas: White Cay located in the Southern Exumas.
Ambergris Cay, also known as Big Ambergris Cay, is a private residential island located within the Turks and Caicos Islands. Not to be confused with Ambergris Caye in Belize, Ambergris Cay is situated to the southeast of the main chain of the Caicos islands. Adjacent to Ambergris Cay is Little Ambergris Cay, which is an uninhabited natural reserve. Little Ambergris Cay is a unique and significant habitat for a wide range of birds and marine life. Ambergris Cay island is approximately four miles long, one mile wide, and 1,100 acres (4.5 km2) in total.
Cyclura is a genus of lizards in the family Iguanidae. Member species of this genus are commonly known as "cycluras" or more commonly as rock iguanas and only occur on islands in the West Indies. Rock iguanas have a high degree of endemism, with in most cases a single species or subspecies restricted to an individual island.
Cyclura pinguis, the Anegada rock iguana, Anegada ground iguana or stout iguana, is a critically endangered species of lizard of the genus Cyclura belonging to the family Iguanidae. The species can be found exclusively in the islands of Anegada and Guana. Historically, it inhabited the islands of Puerto Rico and Saint Thomas, however, the animal's original range has been greatly diminished over prehistory.
