Spiny-tailed Iguana (ctenosaura oedirhina). Local folk call it "Wish A Willa" or just "Black Iguana".
It is endemic to Honduras and the island of Roatan, for which it is named.
It is often seen on the tropical beaches around the iron coral sunbathing!
This photo was taken on the iron shore by the black rock at West Bay Beach.
This photo is dedicated to Debbi Rogers for her love of lizards
