Iguanidae

[i′gwän·ə‚dē]
(vertebrate zoology)
A family of reptiles in the order Squamata having teeth fixed to the inner edge of the jaws, a nonretractile tongue, a compressed body, five clawed toes, and a long but rarely prehensile tail.

Iguanidae

 

a family of reptiles of the order Sauria. In contrast to representatives of the closely related family Agamidae, the teeth of the Iguanidae are attached to the interior surface of the jaws. There are more than 50 genera, including Iguana, Anolis, Basiliscus, Conolophus, and Phrynosoma (horned toads), comprising about 700 species. The Iguanidae are distributed predominantly in the western hemisphere. In the eastern hemisphere they are found only in Madagascar (three species), in Fiji, and on the Society Islands (two species). The majority live in forests on trees. Many inhabit deserts and mountains, and some lead a semiaquatic mode of existence, hiding in water in the event of danger. They feed mainly on insects and other small invertebrates; some are herbivorous (for example the marine iguana). The majority are oviparous; some are ovoviviparous. The genus Iguana (two species) primarily inhabits the tropical portion of South America. Members of this genus are bright green lizards measuring up to 1.8 m long. They live on trees, usually near water; they are herbivorous. Their flesh and eggs are edible.

On the contrary, the opposite general taxon Iguanidae (sensu Boulenger, 1895) postulated in the paper by Schulte et al.
Similar lepidosis, though with visible tendency to polymorphism is shown by the interesting taxon Iguanidae (sensu Frost et al.
Generic and specific variations occur in other families such as Hoplocercidae, Corytophanidae, Iguanidae, Liolaemidae, already with a recognizable Pleurodont brand, however with some primitive characters as in Opluridae, and exceptional divergence perhaps adaptive as in Crotaphytidae.
We analyzed phylogenetic relationships (1) of the lizard and snake families; (2) within eight families (Boidae, Colubridae, Elapidae, Typhlopidae, Viperidae, Anguidae, Iguanidae, and Scincidae); (3) within ten subfamilies (Alsophiinae, Colubrinae, Natricinae, and Psammophiinae for Colubridae; Viperinae and Crotalinae for Viperidae; Diploglossinae and Gerrhonotinae for Anguidae; and Lygosominae and Scincinae for Scincidae); and (4) within seven genera (Elaphe and Natrix for Colubridae; Agkistrodon and Trimeresurus for Viperidae; Diploglossus and Elgeria for Anguidae; and Eumeces for Scincidae).
Hence, the cooccurences in eight families (Boidae, Colubridae, Elapidae, Typhlopidae, Viperidae, Anguidae, Iguanidae, and Scincidae) of egg guarding and viviparous species may relate to common causation rather than to one factor (egg guarding) preadapting a species for another (viviparity).
