On March 30, 2015, I was at home when suddenly my wife came to tell me about an unexpected visitor in our garden. To my surprise it was a beautiful specimen of the Green Iguana (Iguana iguana). It stayed still while I took some nice up close portraits. Iguana iguana is native to Central and South America, and was introduced into Puerto Rico in the 1970s as a result of pet trade. This reptile has spread throughout Puerto Rico, where its negative effects may threaten local biodiversity.
