Brief SummaryRead full entry
BiologyThe Cayman Islands ground iguana has a generalist diet, feeding on the leaves, fruit and flowers of a wide variety of plants. When available, animal matter such as land crabs will also be scavenged, or slow-moving insects will be preyed upon. Certain seasonal changes in the diet are evident, particularly in the exploitation of fruits that are more widely available with the rainy season (4). The reproductive behaviour of this iguana is similar to that of other rock iguanas (Cyclura), with males displaying strong territorialism, aggressively defending access to females within their territory. The smallest, youngest males do not hold territories and during the breeding season move from one territory to another attempting to court females and avoid detection by resident males (4). Courtship and mating have been recorded in April and early May for the Lesser Caymans iguana subspecies. Mating is polygynous (4) and males display to females using a series of 'head-bobs' to attract them (5). After sexual maturity is attained at two to three years, females will produce a single clutch of 7 to 30 eggs each year, laid into a nest dug in the sand. For the Lesser Caymans iguana subspecies, this occurs between late May and mid-June, coinciding with the onset of the rainy season (4). Females only appear to demonstrate territorial behaviour while nesting (4).
