Iguana with open mouth

.

This lizard  in the Negev Zoo near Beer Sheva is an Iguana iguana or Green iguana, native to South America.
Enlarge the photos a few times to see his amazing textures.
He has impressive spines and dewlap.

Suddenly he opened his mouth wide.
Wonder what he was saying to the female.
