You'd think the divers in the following video would be swimming to safety in the presence of the marine iguana that comes swimming through.
Seriously. The thing looks like Godzilla. That's even it's nickname.
Check it out.
Steve Winkworth, at Cabo Marshall, a dive site off the north coast of Isabela in the Galapagos Islands, took the remarkable, almost scary, video.
At six feet long, the marine iguana would be a frightening sight anywhere and the Godzilla-like creatures can dive almost 30-feet deep. The video had its own soundtrack, but if you listen carefully, you can hear the strains of Blue Oyster Cult.
Fortunately, the marine iguana, like the one in the video, are vegetarians.
