Although quick to flee when attacked or threatened, they will aggressively attack by biting and repeatedly striking with their thick tail if cornered. The rhinoceros iguana is a diurnal species living primarily in rocky outcroppings with little vegetation for cover. This sighting represents a new area previously not thought to be in the range of Cyclura cornata. The rhinoceros iguanas caught on Limbe Island are eaten by the local population. It had been caught by a group of fishermen from Bas-Limbe, Bord de Mer village.
An individual was photographed on on the Limbe Island in Northern Haiti. In general, the iguanas are found most abundantly in, although not restricted to, scrub woodland, dry forests characterized by xeric, rocky habitats of eroded limestone in coastal terraces and lowlands of the mainland and several offshore islands and small cays in a variety of subtropical life zones and habitat types. Populations in Haiti are even more endangered due to the deforestation and human clearing practices. There are moderately dense populations in the southeastern region of Haiti and its offshore islands including the saltwater lake of Etang Saumatre. Ranging throughout Hispaniola, Haiti and the Dominican Republic rhinoceros iguana populations are stable only on Isla Beata and the extreme of the Barahona Peninsula inside Parque Nacional Jaragua. This species, like other species of Cyclura, is sexually dimorphic males are larger than females, and have more prominent dorsal crests and "horns" in addition to large femoral pores on their thighs, which are used to release pheromones. Males possess an adipose pad in the form of a helmet on the occipital region of the head, and a large dewlap. Their colour is a uniform gray to brown drab. A crest of pointed horned scales extends from the nape of their neck to the tip of their tail. Thomas Wiewandt, who spent an extended period on Mona Island studying Cyclura cornuta stejnegeri, suggested that the horns, along with lateral spines and prominent parietal bulges, function as protective armor against sharp rocks or as defensive tools to facilitate the escape of males from the grasp of one another. The rhinoceros iguana, like other members of the genus Cyclura, is a large-bodied, heavy-headed lizard with strong legs and a vertically flattened tail. These iguanas are characterized by the growth of bony prominent tubercles on their snouts which resemble horns. Conservation of the herpetofauna of the Dominican Republic.

Rhinoceros iguanas are primarily terrestrial and rarely climb.Īs an ectotherm they must bask in the sun to generate body heat. Sexual maturity is reached between 2 and 3 years old. After hatching the eggs are independent with no further parental care provided. Hispaniola is the only Caribbean Island with two species of Rock Iguanas, genus Cyclura. The geologic history and resulting complex topography of the island has led to significant differentiation across various taxonomic groups. Females remain with their nests for the first few weeks of the incubation period to ward off predators.įemales will dig a burrow of up to 1.5m (5ft) long in the sand where the eggs are laid. Hispaniola is the second largest island in the Caribbean and harbors an extensive amount of biodiversity. This occurs 40 days after mating takes place. These displays include a range of body movements such as head-bobing and gyrating along with raising up the spines on their back.įollowing a successful mating the female will dig a nest hole in to which she deposits up to 20 eggs. Males will perform displays which both attract a mate and help to ward off rival males. During breeding season the male will become highly territorial.
