Silver Ounce 2012 Animal Skins - Blue Iguana, Coin from Niue - detailed information

Niue, a sovereign state in free association with New Zealand, uses two official legal tender currencies. The New Zealand Dollar is the circulation currency for daily transactions, while the government also authorises legal tender coins in the Niue Dollar currency for collector's purposes.

A number of mints issue a large variety of commemorative, bullion and collector coins under the authority of Niue. These coins are dedicated to historical or general popular culture themes not related to Niue itself. Many of them are in standard bullion sizes - typically, one ounce of silver (abbreviated as 1 oz Ag, where "Ag" comes from the Latin word for silver, Argentum). Many of these feature various animals.

This coin is the first release in the Animal Skins series and depicts the Blue Iguana.

The Blue Iguana (Cyclura lewisi) is a critically endangered species of lizard of the genus Cyclura.Previously listed as a subspecies of the Cuban Iguana, it was reclassified as a separate species in 2004 because of genetic differences discovered four years earlier. The Blue Iguana is one of the longest-living species of lizard (possibly up to 69 years).

The Blue Iguana prefers dwelling in rocky, sunlit, open areas in dry forests or near the shore, as the females must dig holes in the sand to lay eggs in June and July. A possible second clutch is laid in September. The Blue Iguana’s vegetarian diet includes plants, fruits, and flowers.

Its coloration is tan to grey with a bluish cast that is more pronounced during the breeding season and more so in males. It is large and heavy-bodied with a dorsal crest of short spines running from the base of the neck to the end of the tail.

The fossil record indicates that the Blue Iguana was abundant before European colonisation; but fewer than 15 animals remained in the wild by 2003, and this wild population was predicted to become extinct within the first decade of the 21st century. These iguanas, when happy, exhibit a beautiful turquoise blue colour. When they are cold or stressed, they are green. The irises of their eyes tend to be a deep reddish-brown, and they generally have black skin surrounding the scales on their bodies, heads, tails and dewlaps.
