La iguana de roca de las Bahamas del norte (Cyclura cychlura) es una especie de lagarto del género Cyclura que se encuentra en las islas de Andros y Exuma en las Bahamas. Su estado en la Lista Roja de la UICN es Vulnerable, con una población silvestre de menos de 5.000 animales.
Sus parientes más cercanos son Cyclura nubila en Cuba, y Cyclura lewisi en Gran Caimán. Los tres aparentemente divergieron de un ancestro común hace unos 3 millones de años.
El nombre genérico "Cyclura" del iguana de roca de las Bahamas del norte y el nombre específico "Cychlura" derivan del griego clásico Cyclos que significa "circular" y Oura que significa "cola", ya que la cola rolliza y anillada es característica de todos los cycluridos.
(Grades 5–7) The Andros iguana Cyclura cychlura cychlura is the largest native land animal on Andros Island, Bahamas. Like many of its Caribbean rock iguana kin, this large lizard is endangered. The iguanas' primary threats are cats that eat juveniles, dogs that kill adults, and hogs that destroy the termite mounds that the females use as their nest. This education kit is designed to help students understand more about this endangered rock iguana’s situation and what we can do about it.
Where Have All the Iguanas Gone? This activity helps students understand that native iguanas survive in just 40 percent of their original habitat.

Iguana Bead Tagging Students mimic scientists by using bead tags to help them identify individual iguanas for research over time.
Make a Sign, Save an Iguana Protecting iguanas from cats, dogs, pigs, and humans is a big job. This activity has students use their creativity to make signs that will work to educate people about the importance of protecting iguanas from humans and nonnative animals.
Buddies or Siblings? Determining Relatedness in Anegada Iguanas
(Grades 9–12) When six confiscated Anegada iguanas were given to the San Diego Zoo by authorities, it was a mixed blessing. On one hand, they were the only representatives of the critically endangered species outside of the British Virgin Islands. And if keepers at the Zoo could get them to breed, the iguanas would become the founders of a captive population, serving to safeguard against the loss of the few hundred individuals left on the Caribbean island of Anegada. But first we had to know if and how these iguanas were related. To get to the bottom of this mystery, scientists knew they would have to compare the genes of the six iguanas to those of the wild population. Like most animals, including humans, iguanas have two microsatellites at each locus, or point, where a microsatellite occurs: one microsatellite from each parent. This lesson helps introduce students to methods for examining microsatellites to determine relatedness.

The northern Bahamian rock iguana (Cyclura cychlura) is a species of lizard of the genus Cyclura that is found on the Andros and 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 northern Bahamian rock iguana's generic name Cyclura and specific name Cychlura are derived from the Ancient Greek cyclos meaning "circular" and ourá meaning "tail", after the thick-ringed tail characteristic of all cyclurids. Its closest relatives are Cyclura nubila on Cuba, and Cyclura lewisi on Grand Cayman. All three apparently diverged from a common ancestor some 3 million years ago.
There are three subspecies of the northern Bahamian rock iguana: the Andros Island iguana (Cyclura cychlura cychlura), Allen's Cay iguana (Cyclura cychlura inornata), and the Exuma Island iguana (Cyclura cychlura figginsi). Biologist Catherine Malone describes C. c. cychlura as being phylogenetically different from C. c. figginisi and C. c. inornata but does not recognize them as separate species; the three are listed as subspecies until further study has been completed.

Beyond the white sand beaches and the idyllic turquoise water, the 3,000 islands and islets of the Bahamas are scattered across nearly 170,000 square kilometers of the Atlantic Ocean.
Captured in 4k cinematography, combined with intimate aerials, extraordinary macro photography and signature ‘tide lapses’ Bahama Blue is this Bahamas beyond the beaches. Explore worlds where everything is eating…or being eaten, but fierce competition gives way to playful and funny creatures, just staking their claim. This a magical place where plants are sprinkled with shimmering dust and seahorses feed, almost without fear.
Dive the amazing caves and blue holes to find biological anomalies who thrive in dark waters saturated with hydrogen sulfide gas and low in oxygen. Penetrate the tangle of Mangroves growing from a salty swamp that houses a nursery of fish and invertebrates until they are big enough, and smart enough, to compete on the coral reefs. Visit the beautiful beaches the Bahamas are famous for, shaped from sand flats in and out of the water: so ubiquitous, that creatures have evolved to hide in plain sight to survive. Experience day and night on a coral reef colony, and find out who is best hidden away when the sun goes down and the sharks come out. Discover the Bahamas from its tiny thimble jellyfish to the gigantic sperm whale and all the creatures in between.
