Generally, species are described as being diurnal or nocturnal active, depending on physiological limitations; diurnal species are not able to perceive their world in the absence of sunlight. Rare are observations reported where diurnal species are nocturnally active.

Common Green Iguanas (Iguana iguana) and Spiny-tailed Iguanas (Ctenosaura similis and C. pectinata) are native to Neotropical regions. These reptiles have been redistributed
beyond their native ranges primarily via the pet trade, for human consumption, or as unintended commensals in horticultural and construction shipments (IUCN SSC Iguana Specialist
Group, 2017; van den Burg et al., 2020a). As such, these intentional and accidental releases have led to established and uncontrolled invasive alien iguana populations in >25 countries, with islands being most vulnerable (IUCN SSC Iguana Specialist Group, 2017; van den Burg et al., 2020b).

Mainly since the 60’s has the green iguana continuously expanded its nonnative range, especially throughout the Greater Caribbean region, and despite repeated warning for its consequences. Now scientists and conservationists are sounding the alarm in a “Letter from the Conservation Frontline”.
