The Tokay gecko is the second largest gecko in the world. Tokay Gecko males can reach 12-14" in total length. Female Tokay geckos are slightly smaller averaging 8-10" long.
An adult tokay gecko averages 5-7 ounces in weight, but particularly large males may achieve weights closer to 11.5 ounces. Hatchling tokay geckos start life at 3.5"-4" and reach breeding age in 9-12 months, but it may take up to 2 years for a tokay gecko to reach is full adult size.
Male tokay geckos are a blue-grey body color with spotting that varies in color from redish-orange to whitish-yellow. Females tokays are a grey body color with the same spotting and generally not as brightly colored as the males. Both sexes have the ability to lighten and darken their skin to some degree to help them blend into their surroundings.
