Natural History:
This
critically endangered lizard is called the most endangered iguana on earth
by researchers. Recent surveys put wild populations at 15-30 individuals,
though captive propagation efforts have been successful in keeping total
numbers much higher. Causes of extermination include habitat destruction
and predation by feral animals, notably introduced rats and cats.
The
success in breeding these animals no doubt is partly related to their
beautiful blue coloring, making them highly desirable species with which
to work. They are also considerably slimmer in aspect than other Cyclura,
arguably making them the most striking of the rhinoceros iguanas.
These
are huge lizards, growing to some five feet in length and weighing in
excess of 18 pounds as adults. The head is notably more elongate and
depressed in shape than all other species of Cyclura except C.
nubila. Blue iguanas are naturally residents of dry scrub where they
are primarily terrestrial. Young iguanas, and to a lesser extent adults,
may climb when in search of foods, including fruits, soft leaves, and
flowers.
