While Wikipedia is not a web directory, external links are allowed where appropriate. They generally are listed under a == level 2 heading == called "External links", even if there is only one link. The best way to create external links is to type "[URL link title]". For example, [http://www.wikibooks.org Wikibooks] will become Wikibooks. However, such short link titles generally are frowned upon.
Try to describe your external links, so that the reader has a pretty good idea where it will take them before clicking on it. In the body of articles, do not use external links where Wikipedia links exist. For example, in an article about Wikimedia, a link to Wikibooks (the Wikipedia article about the project) would be more appropriate than a direct link to Wikibooks.org.
Curly-tailed lizards (Leiocephalidae) are a family of iguanian lizards found in the West Indies, with extant species in the Bahamas, the Turks and Caicos Islands, the Cayman Islands, Cuba, Haiti, and the Dominican Republic. There are presently 30 known species in this family, all of which are members of the genus Leiocephalus. Curly-tailed lizards vary in size depending on species, but typically are approximately 9 centimetres (3.5 inches) in snout-to-vent length. As implied by the name, most species of this family exhibit a curling of the tail. This is done both when a potential predator is present, showing the fitness of the lizard to a would-be predator and – in the case of an attack – drawing attention to the tail, which increases the lizard's chance of escaping. The tail is often also curled when predators are not present, however. Curly-tailed lizards mostly forage on arthropods such as insects, but also commonly consume flowers and fruits. Large individuals can eat small vertebrates, including anoles. This curly-tailed lizard of the species Leiocephalus varius, the Cayman curlytail, was photographed on the coast in George Town on the island of Grand Cayman.
