How to identify Black iguana
The black iguana stands out with its striking, sturdy build and grey-brown to black base colour. The dark stripes across back, legs and tail are conspicuous and often show even stronger contrast in young animals. Its broad head and jaw area in particular make it unmistakable.
It reaches up to 1.3 metres in length, with roughly half of that taken up by the tail. The distinctive dorsal crest with pointed scales runs continuously as far as the base of the tail. Don’t confuse it with the green iguana species, which has smoother skin and less robust head scalation.
