"Blue Iguana," Wikipedia, the free encyclopedia. The adult blue iguana is typically dark gray matching the karst rock of its landscape. The animal changes its color to blue when it is in the presence of other iguanas to signal and establish territory. The blue color is more pronounced in males of the species. Their distinctive black feet stand in contrast to their lighter overall body color. Blue iguanas are sexually dimorphic; males are larger and have more prominent dorsal crests as well as larger femoral pores on their thighs, which are used to release pheromones. The blue iguana's eyes have a golden iris and red sclera.
