An iguana has been named a ''tiny adorable Godzilla'' for his likeness to the fictional Japanese monster.

The herbivorous lizard was filmed underwater eating algae off the bedrock and looked scarily similar to the Japanese fiend who crashed through Honolulu and San Francisco in the 2014 science fiction blockbuster of the same name.

People online are shocked by the marine iguana's likeness to Godzilla, who is no less than 50 metres tall in the film.

Steve Winkworth originally captured the footage at Cabo Marshall in the Pacific Ocean's Galapagos Islands but a recent Reddit thread has made the ''tiny Godzilla'' famous.

One wrote: ''From behind the safety of my computer screen, its surely adorable. If i were in the water though, nope nope nope nope (sic)''.

Another commented beneath the video: ''A tiny adorable Godzilla.''
