The reptile was seen in Nakhon Ratchasima, northeastern Thailand, on January 6 by visitor Thananan Ruannak and his wife.

Footage shows the iguana confidently strolling through the territory belonging to the primates without a second thought for the hosts.

Thanana said the iguana appeared to be comfortable in the home of different species. He said: "The iguana showed no fear being in another enclosure and made itself at home."
