These tiny iguanas can easily fit in the palm of a hand. Contributions to West Indian herpetology: a tribute to Albert Schwartz, 12 [ed. The colder winter temperature regime not only reduc­es activity but also limits growth rate and could retard sexual maturation. Field personnel shot iguanas when prudent and safe during regular pa­trols of the study area using a .22 caliber rifle or air rifle (Avery et al., 2014). It generally is found in seasonally dry, lowland habitats but can occur in sites up to 900 m elevation. After digging a burrow about half a meter deep, the female lays 2 to 25 eggs in the nest.

Fitch and Henderson (1978) report that in Nicaragua hatchlings grew to >140 mm SVL and >80 g body mass within 6 months. Despite their size, they appear to be quite agile; it was not unusual to see the large black spiny-tail iguanas (Ctenosaura similis) high up in trees. Young iguanas often remain in groups with one of them temporarily behave as the leader. Natural history of the black spiny-tailed iguana (Ctenosaura similis) at Parque Nacional Palo Verde, Costa Rica, with comments on the conservation of the genus Ctenosaura. The iguanas' reaction to the cries is to "freeze" and they are then easily caught (Murphy 1989). This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico. Female total length is just under a meter (87 cm) and weight is closer to 1 kg. First record of the spiny-tailed Iguana Ctenosaura similis (Gray, 1831) (Squamata: Iguanidae) in Venezuela.

Life Cycle Adult C. similis can reach lengths of 4 ft and are predominately black in color. On Gasparilla Island, hatchlings (minimum 43 mm SVL, 2.75 g body mass) were observed from the last week of July until early October, with 97.5% of the hatchling iguanas encountered in August and September (Avery et al., 2014).

C. similis now occurs on Keeywadin Island, Little Marco Island, Cayo Costa, and probably other islands as a result of purposeful transport and releases by residents (Krysko et al., 2003). Size-selected Harvesting of a Common Iguana Species (Ctenosaura similis): Possible Impacts on Population Structure, Sexual Dimorphism, and Social Dynamics. Distribution of the introduced black spiny-tailed iguana (Ctenosaura similis) on the southwestern coast of Florida. The genusCtenosaura (spiny-tailed iguanas) is wide-ly distributed in semi-humid lowlands from central Mex-ico to Panama (Ethridge 1982). Juveniles tend to be olive-green becoming tan and then finally greyish as they grow (Grzimek 1990; Roberts and Roberts 1993; Cogger and Zweifel 1998). Size-selected harvesting, where hunters preferentially take large size classes of a population, is well documented in many exploited species. Ctenosaura similis, commonly known as the black spiny tailed iguana, black iguana, or black ctenosaur, is a lizard native to Mexico and Central America. Ervin, D. 1992.
