The coloring of the Lesser Antillean iguana (Iguana delicatissima) is variable and therefore does not constitute a characteristic nor a distinctive element of the species. In the juvenile stage, all individuals are apple green, with lighter markings on the lower jaw, the shoulders, and the flanks. As they grow, their tail becomes more and more brown starting from its tip, and the lighter body markings are less pronounced. In adulthood, the coloration of males varies from light gray to dark gray-brown. That of females is very different from one population to another depending on the habitat. In a humid environment, their coloring can be entirely green or include darker areas. In a dry environment, on the other hand, it approaches the gray-brown of males, however retaining isolated green spots or scales, especially on the belly.
