We need to protect these animals because we are running out of time before they disappear forever. The massive head of the male is topped by 3 horn-like tubercles and a thick adipose fat pad.
Top Rhinoceros iguana threats The main threat facing this species is habitat loss as a result of logging for hardwoods, exploitation for charcoal production and fuel wood, livestock grazing, agriculture and mining of limestone.
The interior population is believed to have been attracted to agricultural clearings and fruit farms which provide thermoregulatory opportunities, herbaceous browse, fallen fruit, and nesting soil, but this brought the blue iguana into contact with humans and feral animals.

All are island endemics Cuba, Jamaica, Caymans, Bahamas and critically endangered. We all recognize this huge animal in the zoos or in pictures. It is as if we are going back years.
They emphasized its overall bright blue coloration, and noted that further study could reveal it to be a distinct species. East End people say that since the "guanas"[sic] have become so scarce that it is no longer worth their while to hunt them.
This is the reason they are endangered; people like to collect their horns because they are made of keratin.
Land clearance within remnant habitat is occurring for agriculture, road construction, and real estate development and speculation. Over half of their habitat in the Dominican Republic is gone, and the remainder is severely degraded; the situation appears far worse in Haiti.
At the same time, they have cells called " double cones " which give them sharp color vision and enable them to see ultraviolet wavelengths. Mating occurs in May and June. When we think about this animal, we usually visualize his big horn.The horns of the rhino are the exact same substance as fingernails (keratin).
