Iguana

Found at Palo Verde Biological Station, inside Palo Verde National Park. Guanacaste Province, Costa Rica.

 

Presumably Black Spiny-tailed Iguana - Ctenosaura similis. Confirmation/correction welcomed.

 

Several of these were resident around the station. Some were marked for a recent study with colorful beads behind the head.

 

Single exposure, uncropped, handheld, in situ. Canon MT-24EX flash unit, Ian McConnachie diffuser.
