Spiny-tailed iguanas (Ctenosaura similis) in Venezuela: a preliminary report. Furthermore, within Florida, subsequent purposeful transport and introductions have exacerbated the potential impacts of ctenosaurs on native fauna (Krysko et al., 2003). This species becomes sexually mature at around 3 or 4 years of age. She must also signal that she is receptive-with mature ova ready for fertilization.

The male black spiny-tails can grow as large as 4 ft 3 in (1.3 m), while females are a foot or more shorter.

Henderson Museum of Natural History, University of Kansas, Lawrence, Kansas 66044 ABSTRACT-A small population of Ctenosaura similis was studied in Belize, British Honduras. This species is not usually raised in captivity for meat production because, in contrast to Iguana iguana, successful captive rearing of C. similis is very difficult (Stephen et al., 2011). Montanucci RR, 1968. Accessed Ctenosaura similis, commonly known as the black spiny tailed iguana, black iguana, or black ctenosaur, Tulum Mexico. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia. Help us improve the site by taking our survey. Zootaxa, 3028:1-64. Their tails are not as proportionately long as, say, the green iguana, so visualize the body size of an adult C. melanosterna equal to that of a 4ft green iguana. Egg-laying takes place in the dry season, and hatching occurs just before the onset of the wet season. Summary .
