Copper Skink

About the Copper Skink

The copper skink (Oligosoma aeneum) is a skink of the family Scincidae that is endemic to the North Island of New Zealand. The number of skink species endemic to New Zealand is not yet known, as advancing molecular studies indicate genetic divergence amongst many groups previously considered a single species. At present, there is estimated to be between 50 and 60 species, all of the family Scincidae. Following a taxonomic revision of the species complex in 2008, the copper skink was assigned the scientific name of Cyclodina aenea, and found to be both genetically and morphologically diverged from two other skink species that were previously considered synonymic.

The initial arrival of the copper skink (and indeed any other skink species) to New Zealand is somewhat uncertain, and is a topic of considerable debate. The level of genetic diversity between the copper skink and other indigenous species suggests strongly that they and their ancestors have been a part of New Zealand's fauna for millions of years, allowing time for many early species to diverge and become distinct from each other.
